After launching a site, its owners should thoroughly check the security of it, in order to prevent possible problems and increase the user satisfaction, this process is actually like site updates that need to be done on a regular basis, which needs to be checked regularly to prevent cyber attacks.

What is website security?
It is a set of measures that are generally taken to ensure the site has the highest possible level of security to be protected from possible cyber attacks, simply put, website security is a process that should be done to prevent a site from being hacked.

What makes website security important?
Website security is of particular importance it’s better to say that not having a site is better than having a hacked site with a large number  of dissatisfied users, even if website owners follow all the principles of site optimization and attract many users to their websites, but they do not care about the security of them, a cyberattack may occur, as a result their user numbers will decrease, and even when they find the cause of the problem and fix it, users will not be satisfied because they lost their trust in those websites, so they will get a negative ranking on the Google search results page, therefore you should always pay attention to the phrase ‘Prevention is better than cure’ to avoid possible threats, in fact, another factor that makes site security particularly important is hidden in this phrase, in a way that if you have not checked your site in terms of security and all the ways that hackers may use it to access your website, your website will be attacked by hackers, so you have to spend more time and energy to be able to return your site to its normal state, in general, the security of the site is of special importance, so in order to prevent your site from being hacked, we suggest you to read this article and pay attention to the following strategies.

Steps to take to secure your website:
1. Take the security of web servers seriously:
In fact, the web server has the task of storing the existing content and sending it to the client who requested it, the content that the web server should store and send may be in the form of text, photos, videos, and so on, the most common type of client that requests content from a web server are browsers, there are many points about web servers that if you pay attention to them, they will help you secure web servers, also, if you have data that does not need to be on the web server, you have to delete it, and don’t make them publicly available.

2. Choosing a suitable and quality host:
Another step that can be taken to ensure the security of the site is a correct and principled choice of host, there are many factors to consider while choosing a suitable host, the reason of its importance is due to the fact that most of the attacks on the site are done through the hosting platform, while choosing the right host, you should not only pay attention to its price, and you must do a lot of research as well as paying attention to the opinions of other users who have used these hosts to make sure that you have chosen the best company to buy the host, you should also pay attention to the security that the company has provided.

3. Use reputable software:
Using reputable software can greatly help the security of the site , if you prefer similar versions of the software to the original versions of it, you may certainly provide some ways for hackers to access your website which is harmful for the security of it.

4. Be careful in choosing your password:
Hacking a site is a complex issue that can be prevented by doing a number of things, one of the steps that can be taken to prevent the site from being attacked by hackers is to be careful in choosing the passwords, there are some principles for choosing the right password that must be properly observed to ensure the security of the site, the password that you choose should be more than eight characters and also a combination of numbers, letters and characters, etc., so that by choosing the right password, you can create a secure site that users prefer to use because of its safety.

5. Check the site regularly:
Automatic updates can seriously damage the structure of the site, for example, imagine that your site automatically replaces unsupported and unreliable software, in which case your site security will be compromised, but if you check the site regularly, you can easily and quickly realize the changes that occurs on the site and try to improve the quality of it.

6. Examine the platforms provided for user interaction:
One of the ways that can help increase the site's ranking is to interact with users, therefore site owners dedicate a platform on their site for this interaction, on the other hand it may make your website more accessible to hackers, so it will comprise the security of the site, therefore these platforms should be limited as much as possible.

7. Back up your data:
If your website is hacked, you may not be able to retrieve the information you lose, for solving this problem, you should use tools that back up your data constantly, therefore you are not worry about losing your information.

8. Use reputable content management systems:
Content management systems play a big role in securing a site, and if you do not use a proper content management system for your site, it may end up with serious security damages, in addition to the actions mentioned, there are other actions that paying attention to each of them and having enough control over them will make a safe site available to users.

9. SSL certificate:
Today, search engines only validate sites that have obtained an SSL certificate , otherwise they will be labeled as insecure sites, in fact, all information entered on the site by the user, such as the user's email, credit card number, etc., is protected by this certificate, so that hackers cannot abuse it.

10. Web application firewall:
Web application firewall stops attacks that are automatically made on the site, these attacks are carried out by bots and usually affect small sites.

11. Kali Linux:
Kali Linux has many applications for penetration testing and identification of weak points of various computer systems, in fact, Kali Linux operating system includes hundreds of different tools for performing security and penetration tests, each of which are able to help websites, Kali Linux has many tools, such as Kismet, Wireshark, John the Ripper, etc., all of which help the site to increase its security.

A site and its users may be affected by the following attacks:
- Defacement:
After this kind of attack, the content of the site which attacked you, replaces the content of your site and ultimately causes great damage to your site.

- Denial-of-service attack:
As a result of this attack, parts of the site are made inaccessible to its users, so that they cannot reach the desired results from your website which causes a decrease in the number of users.

- Malware:
These types of software are made to cause serious damage to the site, which have a wide range that you should be familiar with them to prevent their penetration into your site.

- Blacklisting:
Your site is likely to be removed from the search results page as a result of cyber attacks, which will greatly affect the number of website users.

-Stolen data:
Because of cyber attacks, the information of users who visit your site may be stolen, so that users will gain a negative user experience from your site.

- SEO Spam:
The task that may be done in this part is to replace malicious links and comments in order to confuse the users, so that when users enter your site, they will consider it as a low quality one as a result of these kinds of links and comments.

Last word:
In general, site security is an issue that is very important these days, users around the world prefer a site that has high security, as a result, they can trust them and enter their information safely, security is also one of the important factors that site owners pay attention to and do their best to protect their site from cyber attacks , the importance of this subject made us to provide you with this article, which includes important points about site security.

Many efforts are being made to provide security for sites and their development, nowadays, security issue is one of the obstacles that prevent the widespread development of sites , so we must be able to maintain website security along with the development of them, sometimes programmers make mistakes that cause the site to be easily exploited by hackers, as a result, strategies should be considered while developing sites, the security of a site is so important, because cyber attacks may be carried out by hackers and the information that users have entered to the site may be abused, which has led all website owners to try to ensure the security of their site, one of the solutions is that you can use some kind of programming languages which are being less penetrated by hackers, and you should pay attention to the fact that in most cases, small mistakes in programming lead to irreparable damage to the site.

The following strategies can be effective in increasing site security:
1. Installing security software:
You must be sure to use security software While programming and designing the site, which we will mention some of the best security software available in the following.

- ESET Endpoint Protection Standard:
This software is very suitable for small sites owners who want to increase the security of their websites and are not able to spend a lot of money because it is a budget friendly security software, and it allows the site to be managed remotely by its users.

- Symantec Endpoint Protection Cloud:
This software is very easy to use and can increase the security of the site , but it also has weaknesses, one of which is the inability of this software to report.

- Trend Micro Worry-Free Business Security Services:
This software protects the site from most of the threats posed by the use of malware on the site and keeps it safe.

- Avast Business Antivirus Pro Plus:
This software can be used easily and also provides many features to increase the security of the site, but the point that you should know about this software is that it has a weak point in supporting sites through mobile devices.

- McAfee Endpoint Protection Essential for SMB:
It is one of the best options for protecting small sites which has great reporting capabilities and causes more users to attract to this software in order to increase the security of their site.

- Kaspersky Small Office Security:
One of the important features of this software is having a pre-configured system for maximum protection of the site, which can significantly increase the security of it and is one of the recommended software programs to make your site as secure as possible.

2. Remove the admin page from public access:
If the admin page is hacked, the site will face serious problems, if you want to prevent such things from happening, the best thing to do is to get help from coding, which you need to pay attention to some points and follow some tips to do it correctly, so that hackers cannot easily attack the page.

3. SLL in site design:
SLL in site design can help a lot to increase site security, in fact, this protocol is used to secure the insecure protocols, in other words, when the site information is passing through an insecure communication channel such as the Internet, a series of encryption algorithm are placed on the site information via SLL to prevent the information from being hacked while transferring, it is also important to note that users choose sites that use SLL in their design to get their desired results and the answers of their questions, but you may be wondering how we can tell if a site has used SLL or not, for recognizing it, you must pay attention to the site address, which “HTTPS” must be written instead of “HTTP”, where “s” at the end of HTTP indicates the phrase “secure”, also in this case a lock symbol is seen in the browser through which you can understand that the site is secure.

4. Use high security content management systems in site design:
Content management system is actually a software system containing tools for managing websites, most web users can also use these content management systems to design and launch their site even without programming knowledge, various features should be considered while choosing these systems, one of the most important features that the selected system should have is security. WordPress , Joomla, Drupal, etc., are content management systems that can be used according to the purpose you have in designing the site and also the level of security you need for your website.

5. Choose the right language for programming:
There are many languages for site programming that you should choose the best possible programming language according to your goal in creating the site , which we will introduce a number of programming languages to you in the following.

- python:
This programming language is one of the top ten programming languages in the world, which has many advantages that make people use it, but it should be noted that one of the disadvantages of this language is the slower execution of codes than other programming languages.

- Ruby:
Ruby is a specialized programming language that is a bit difficult to work with, and if you are newly starting, it is better to think of other options.

In general, it is not possible to say which programming language provides more security for your site, and it is necessary to choose the best possible language according to the goal you have in designing the site .

6. Install antivirus on your PC:
While programming and designing a site , you should pay attention to your personal computer and make sure that it is safe, because there may be malicious files on your computer that can cause all the information on your computer to be in danger, as a result you can get help from existing antiviruses, the best ones can be mentioned as follows.

- Sophos home:
This antivirus is for free, like the previous one, and offers many features to the user.

7. Do not save the password:
For better development of the site, you should constantly check it and log in through the site management panel, where some people save their password by the browser for easier and faster access, which is dangerous and affects the security of the site , because when you give your computer to someone else, he/she can easily access all parts of your site and make changes that may destroy your site.

8. Check all the information entered by the user:
There may be illegal characters in the data sent by the user, which causes damage to the site as well as its security, so all the information that users enter the site should be examined.

9. Check the security bugs of the site:
Even if you observe all the applicable points to increase the security level of the site in programming, site design, etc., you may still be notified of bugs by users or by checking your site, the best solution is to fix all the bugs quickly to increase the security of it and provide users with a good user experience, not paying attention to this point can cause the sites to gradually gain low security and be attacked by many hackers.

Last word:

Physical security is an important part of security that must be done properly in order to keep all information secure, as you know, network, information and software security are important, but they can be proceeded when you are sure of physical security and there is no disruption in this field.

What is physical security?
Physical security is the protection of hardware and software components , networks, and data from physical conditions and events that may cause serious harm to an organization, in other words, physical security includes all tasks that is done to protect information, hardware, and software from possible problems like stealing, etc., to achieve this security, it is necessary to take steps that we will mention them in the following.

Physical security can be created in a variety of ways, the choice of which depends on the information that you want to protect, as well as the problems that are to be prevented from occurring.

Physical Threats:
- Treats that may occur naturally which will damage the information that is to be protected, including floods, storms, tsunamis, volcanoes, earthquakes, etc.

- Disruption of natural conditions, for example, a sudden rise in temperature or high humidity, which you should be able to provide physical security for existing information in some way in this situation, there are other conditions that may happen, such as lightning, heavy rain, and so on.

- People may want to destroy existing information on purpose, through destruction, theft, fire, etc., all of which is necessary to deal with before they occur, so even if they happen, there are no worries in this field, because the solutions were thought before, as a result they cannot do much damage to the available information, sometimes a person may cause some events inadvertently which may be the reason of irreparable damage, for example, imagine that someone is working on his/her system and suddenly spills the coffee on it, which there are some tasks to do in a way that by implementing them you can protect your information from such incidents, as we have mentioned above, the importance of information also affects the steps that are taken to protect them, in the following, we will mention each of these events and the actions that can be done in order to prevent the loss of information when they occur.

What steps can be taken in general to build physical security?
1. Pay attention to the importance of a safe building:
Imagine that you have information that is so valuable, and you need to keep this information safe from any unexpected event, for achieving your goal you must do the following steps to make a building safe .

- A safe building must have a high level of safety against fire or any other kind of incident, for this purpose, you must use some special equipment for the building which includes some properties like being fireproof because of its ability to minimize damage in this case.

- Entrances and exits should be limited to make the process of controlling easier, as a result, they can be easily protected by security personnel, another important point that should be considered is controlling windows, which should be blocked.

- If you feel any small changes in the entrances to the building or room that contains important information, you should change the locks and even the people who protect them.

- A safe building should have an alarm, so that, it informs you in case of any abnormality, as a result you can create more physical security.

- A safe building should have an automatic fire extinguishing system to be able to extinguish the fire which may be intentionally caused by people, or due to incorrect electrification, and as you know, water can cause more damage to the computer system and destroy all of the information, so alternative methods should be used instead of water to provide the best possible physical security.

- In order for events to happen as little as possible, such as pouring coffee and the things like that, you should make it into a law that people are not allowed to drink, eat, smoke, etc., after entering such buildings and rooms, so that you should make every effort to maintain physical security and protect information and systems.

 2. Separate public systems from the ones that contain more important information:
- You should separate the systems depending on the importance of each, and apply different physical security to keep them safe.

- The location of the systems should be chosen based on the available information, for example, systems that contain sensitive and important information should be located in a place where it is protected, so that no one can reach it or try to abuse it due to the fact that there are lots of people who are trying to protect the information as much as possible.

- Keep all important information about the equipment in a safe place, for instance the equipment code, so that you can look for the equipment when you need it or if an accident happens.

- If you need to repair the systems, you may need someone who is specialized in this field, who should be chosen according to the information you have in the system, and you have to remind him to follow all the necessary rules.

3. Steps to be taken to create physical security against theft:
- Equipment that contains information should be marked in such a way that you can easily identify it, as a result, when the thief decides to sell the equipment, he/she cannot sell the available equipment at a high price.

- In addition to the specific markings you make on the system, you should also place some marks inside the system secretly, so that you can prove that the system belongs to you through the presence of such markings in the system.

- Limit the access to the system by people as much as you can, and never allow people to access the system easily and try to have a control over everything that occurs around the system.

- Place the system in the safest possible place and if people are allowed to use the device at your discretion, monitor their activity and do not allow them to be alone with the system for a long time.

- If all your important information is stored in small devices such as laptops, you should be more careful, because they can be easily carried, so you should try to do your best to be able to create as much physical security as possible.

4. Control power supplies:
- The power supplies that systems need them must be properly distributed, so that all systems can receive the electricity they need without disrupting the performance of the resources.

- You should always consider a resource as a backup, so that it can be a good alternative to the current source, and you can use it in a case when an unexpected event happens to the main source.

- Secure existing power supplies against accidents that are likely to occur.

5. Prevent the dissemination of information in the system:
- As mentioned in the safe building section, you have to place the system where there are lots of people who have the duty of monitoring it.

- Monitor devices such as scanners, copiers, etc., so that no one can abuse them in order to have a negative effect on physical security .

- Do not put the confidential information that you intend to delete in the regular trash, because it is not safe, so that you should intend to destroy it completely as soon as possible.

6. Get help from CCTV cameras:
- All the information you have as well as your systems can be controlled by placing CCTV cameras, nowadays, it is also possible to check all your systems through your mobile phone, and you can be notified in a case when any other user tries to log into your system, by a mesغير مجاز مي باشدe which will be sent to you to take the necessary security measures, as a result you will take control of the system again and protect your information in the best possible way.

Last word:
In general, physical security is an issue that is of a great importance these days, you must try different ways to secure the information according to the kind of information that you intend to protect it, in this article, we have mentioned a number of ways to establish physical security that each one needs more attention, and note that if your information is too important, you should be sure to get help from experts in this field to provide the physical security of the site in order to protect your information in the best possible way.

Xbox Series X or PlayStation 5?
This is a question that any person may face while entering the ninth-generation. In this article, we will have a look at the advantages and disadvantages of both consoles so that you can choose the best one. Unlike the 8th generation, Microsoft was cautious about its console and instead of making major changes, tried to evolve the Xbox so that all the Xbox One accessories could be used on the series X/S and tried to make up previous generation mistakes, the Xbox One's hardware weakness and lack of exclusive games . Now they have built the most powerful console of history and bought major first-party studios. On the other hand, Sony wants to continue the path of the previous generation with its successful exclusive games in the last generation so that it can stay at the top of the sales chart.

Designs
Contrary to some of the similarities in Xbox One and PS4 designs , Microsoft and Sony have followed two completely different ways of designing for new consoles. the Xbox has a simpler appearance and a smaller size, but the PS5 is more creatively designed but it’s larger and almost reminds of PS3 fat model designs. While some gamers have complained about the PS4 overheating while playing games like Red Dead Redemption 2 and The Last of Us Part II, the air conditioning works well in PS5 . Unlike the first Xbox One model, there is no power brick beside the Xbox Series X, and the device is still cool and quiet while processing 4K and 120HZ games. You can also use both consoles horizontally and vertically. The PlayStation 5, with its customizable plates, gamers can change the way of how their console look, but the Xbox Series X gives your gaming setup a special grandeur with its integrated black look.

Exclusive games
Sony's exclusive games success over Microsoft in the 8th generation is not denied. Releasing games such as God of war and The Last of Us Part II boosted PS4 sales and even forced Microsoft to buy First Party Studios. The cancellation of some Xbox games, such as Scale Bound and Fable, as well as the run-of-the-mill performance of other exclusives, unlike the seventh-generation, caused Microsoft failure. It can be said that Microsoft's best chance is the backward capability that unlike the PlayStation , runs completely flawless and supports even the Sixth-generation games. Now with the addition of EA Play, a large archive of world premier games is available to Game Pass Users at a low غير مجاز مي باشدt. They also buy more studios after signing one of the most expensive contracts in the history of the video game industry with Bethesda, according to Phil Spencer, head of Microsoft's Xbox.

Looking at Xbox exclusive games, you will find that if you are into racing, shooter, or online games, you can choose this console. But if you are looking for action-adventure games and deeper stories, PlayStation could be your best choice. With the Bethesda contract, we can expect massive RPGs in Game Pass. Also, Sony has announced PS Plus Collection for PS5 which allows you to have access to many PS4 exclusive and multi-platform games like God of War, Battlefield 1, etc.,

Controller
One of the most important strengths of the PS5 is the Dual Sense, which has been released with its adaptive trigger and haptic feedback features. Dual Sense has a cool design and With Astro's playroom, Sony has shown its feature, but we must see if using this feature is easy for other developers or not.

Dual Sense Built-in microphone can be really useful for online players, so you can have a voice chat while playing on TV speakers. Dual Sense Haptic Feedback is a more advanced form of impulse triggers technology used in the Xbox One controller . With this feature, gamers get a real sense of the levels and collisions of the game and find themselves fully in the game environment with 3D sound. adaptive triggers can be added to what we have said. The use of different rifles such as shotguns and bows and arrows will be different in the ninth-generation games of the Sony console, and by adjusting the trigger, you will feel even harder arrows and bows due to the stretch, as well as more difficult to shoot with shotguns. Motivation.

On the other hand, Microsoft has tried to keep its design with minor improvements over the Xbox One controller. They have added a new “share” with redesigned D-pad with more comfortable bumpers. Dual Sense includes problems with the adapter trigger after a while. Also, the use of batteries in the Xbox Series X controller is unpleasant for some gamers.

Hardware
The two ninth-generation consoles are equipped with AMD processors and ZEN 2 architecture with eight similar cores, but there are differences in the GPU. The Xbox series X GPU with 12.5 teraflops of processing power is up against 10.28 teraflops of PlayStation with more numbers of CUs, but both have a custom AMD RDNA 2 architecture. Both consoles have 16GB of GDDR6 RAM, but the maximum amount of PlayStation’s bandwidth is more than the Xbox Series X.

Thanks to the high-speed SSD of PS5 and Xbox Series X, the ninth generation has no longer a boring loading and almost all games load in a few seconds, but due to this generation huge games, 670 GB of PlayStation accessible memory may not be enough and According to Sony, it is not possible to add external memory at the moment, but when this problem is solved with the updates, it’s not too easy. However, you can buy an external SSD for your Xbox Series X right now and use it as easily as old memory cards. PS5’s storage speed has surpassed the Xbox in loading games with a little difference. At gaming tests, these two consoles have been able to cope well with Ray Tracing and HDR, as well as running some games at 120 frames per second. In terms of repairing, both consoles appear to be at the same level, but using liquid metal in the PlayStation makes it a bit difficult to repair.

UI and software
To show off the Xbox power, Microsoft has added a quick resume feature that lets you open up to 6 games at the same time and switch between them whenever you want, but unlike Sony's simple and light user interface, The Xbox is a bit confusing, and this problem remains unresolved after two generations. Xbox has added a dynamic theme to Series X while Sony had a large variety of themes since PS3.

These Two new consoles support Backward compatibility in different ways. Thanks to the Integrated architecture of Xbox consoles , you can Run 4 generation games on Xbox Series X. On the other hand, PS5’s compatibility is limited to PS4. Microsoft engineers have done another miracle besides Backward compatibility. They have been able to greatly increase the refresh rate of eighth-generation games using FPS Mode. Now some previous generation games have even reached 120 frames per second which are wonderful.

Microsoft and Sony are focusing on cloud services with developing project xCloud and PS Now. With xCloud you can play Xbox games on your phone or Personal Computer on the same saved data. PS Now also recommends a good archive that you can play some PS4 and PS3 games on your PlayStation 5.

Price and availability
It can be said that both companies have suffered losses to launch their consoles at a reasonable price, but this loss will be compensated by selling games and subscriptions. You must know that new games in the 9th generation will غير مجاز مي باشدt 10 more dollars which is 70$. We must remind that with the rising غير مجاز مي باشدt of making games, this is not much after years of price stability. Also, a while ago Microsoft decided to increase Game Pass Ultimate and Gold subscription price which was criticized by many gamers. Not only they did not increase the price but also eliminated the need for free games for Gold subscription. Note that Sony did not require PS plus for free games for ages.

Due to the coronavirus pandemic and its limits, the inventory of both consoles was limited, especially in the pre-order and first days of release, and this led to staggering prices on eBay and Both manufacturers have promised to stock up on stores. Both consoles have 499$ price tag, which of course may be unfair that the Xbox presents more power and memory, at least on paper.

Conclusion
However, we are at the beginning of the new generation and multi-platform games that can show the true power of both consoles have not been released yet and we can’t make an accurate graphical comparison between the two consoles and it can be said that the ninth-generation changes are not significant but impressive. Many factors are influencing your decision to buy and choose one of these consoles. You may be impressed by the next God of War and Dual Sense features, or choose the Game Pass and upcoming Xbox exclusives such as Fable and Halo infinite.

The height of Xbox Series X is seven centimeters shorter. Another point that needs to be mentioned is that both of these consoles are ranked among the heaviest available consoles due to date.

Design and dimensions of PS5 and Xbox Series X
Based on official information at Sony.com, the ninth generation of PS5 is six centimeters taller than its foe. The new console of Sony is much higher than the new Xbox. It reaches 37.8 centimeters. The height of Xbox Series X is seven centimeters shorter. Another point that needs to be mentioned is that both of these consoles are ranked among the heaviest available consoles due to date. The optical version of PS5 is almost 4.5 kilograms, and the digital version that is cheaper and doesn’t have any optical drive is nearly 3.9 kilograms. The new Xbox's weight is almost the same as its competitor, but Xbox Series S is way lighter than the digital version of PlayStation , its 1.93 kilograms.

Microsoft did a fair job designing the new Xbox, and It has a cubic shape, and thanks to its black color, you can match it with many of the things in your room. On the other hand, the new PlayStation has a rectangle shape. It has a modern look, but it’s a little bit difficult to match with the room, but possible because of its white color.

Well, by its looks, Xbox Series X has more processing power than the PlayStation 5, but we have to make sure of this in action.

The processing power of PlayStation 5 and Xbox Series X     
At the very own core of Xbox Series X, we have a powerful AMD chip customized exclusively for this console. Microsoft and AMD, despite their last generation differences, did a great collaboration on this. Eight 7nm Zen 2 processing cores are included in this chip, and we have SMT capability to run sixteen threads in parallel.

Xbox Series X has 16GB of GDDR6 memory with a 320-bit interface. If we look at the console's storage part, we see a one terabyte NVMe SSD with a transfer rate of 2400 MB per second. You can also attach other SSDs to the device by the ports in the back of the console.

Again, in PS5 , we also have eight 7nm Zen 2 processing cores, but they are slightly weaker than Xbox because they clock at 3.5 GHz and Xbox clock at 3.8 GHz. PlayStation 5 also has 16GB of GDDR6 RAM and a 256-bit interface. The thing is that PlayStation is more successful in real action, although on the paper it seems a little weaker, but it can run 4K resolution, Ray Tracing On games with higher frame rates and more graphic details. Kudos to Sony for this console.

 PlayStation 5 and Xbox Series X controllers
Xbox Series X controllers did not change drastically compared to the last generation, but it’s an acceptable upgrade. The new controllers seem a lot like the Xbox Elite controllers on the market. The circular pad of the controller has an ergonomic design which is really better than the last generation. You can also use this controller on Windows 10 devices without any problem. Also, keep in mind that you can use the previous generation controllers on the Xbox Series X, but some customers reported that it doesn’t function well, and sometimes it disconnects. Microsoft declined these accusations, but they released an update a few months ago, and now it seems like that it’s solved. If you want a new experience, I suggest you use the new controllers.

On the other hand, PlayStation controllers changed entirely in terms of design, and now instead of DualShock, we have DualSense, which is really cool.

DualSense enhances user experience, and the new PlayStation Controllers are very much similar than before to the Xbox. We have adaptive triggers on the L2 and R2 buttons, and they function and vibrate better than before. Haptic touch is another feature of the DualSense and replaced the old school DC vibration. Xbox had this feature before, but now we get to experience it on the PS5.

Conclusion
Xbox consoles are cheaper than PlayStation, but Microsoft, contrary to Sony, has not yet announced tempting exclusives for its console, and they are buying many new studios. Probably we see some of the great exclusives in the middle of the generation, but for now, Sony is one more step ahead because it has introduced more tempting exclusives and have a much clearer path for their fans, compared to Microsoft that we don’t know many things from its progress in making new exclusives

Finally, I have to say that maybe buying the PlayStation is a better option because of Sony's exclusive games and better support of buyers, and a lovely controller. Although some time has passed since the beginning of the generation, Microsoft has not yet shown much of its original exclusives. Of course, do not forget the Game Pass, you can use Game Pass to get access to many games for only ten dollars a month, and Sony has not yet provided such a service for gamers . But I have to say that buying a console is a personal choice, and some people may prefer the new Xbox to the PlayStation. It's totally up to you.

Servers help users get the answers to their questions in a short while, in fact, when you make a request in a browser, the browser receives and sends information about the answer to your request from the server, information security is very important and all people who deal with the Internet and computer systems are constantly trying to increase the security of their system by taking measures to prevent hackers from infiltrating their systems, it should be noted that hackers are trying to be able to add to their science and knowledge and their power day by day in the field of computers and hacking given that users are trying to increase the security of their systems, so that hackers try to improve their acknowledgement in order not to be stopped by any obstacles, in this article, we are going to discuss how servers are being hacked, but before that, you need to know a little more about the definition of a server.

What is a server?
Simply put, servers are computers that share information with other computers, the servers have a software section as well as hardware, and hackers target the software section more, and by entering this section, they finally gain a lot of information, which we will discuss in more detail later, of course, ethical hackers are constantly trying to find security holes in web servers, and they use exactly the same methods that malicious hackers use for the server, with the difference that the purpose of these hackers is different and if a white hat hacker can hack the server through a path, they will report quickly, so that all security holes will be closed and the way for malicious hackers to enter will be blocked as well.

How can servers get hacked?
Initially, hacking needs gathering information about the goal they intend to achieve, in order to collect information, it is necessary for hackers to gather complete knowledge about the relevant server, its hardware and software parts, configuration, address, etc., gathering information is actually an important part of hacking a server, and if this step is not done properly, taking other steps are somehow impossible and hackers will not be able to reach their goal, the next step is to find the vulnerabilities of the server, so that hackers can access the server through these points, in order to do this, hackers usually use tools to scan for server vulnerabilities, in fact, these tools can check all the security issues on the server and let the hacker know the weaknesses, for example, if the server has a weakness in choosing a password which can be easily obtained, they will let the hackers know about this weak point, other vulnerabilities of a server that may be found by these tools may include incorrect configuration of software on the server, non-updated software on it, and so on.

Hackers may use the following tools to scan servers:
1- Nessus:
Nessus can provide a lot of information to hackers, it can find and report vulnerabilities on a server, using this tool requires payment, but hackers can regain the money which they have spent quickly.

2- Nmap:
Nmap is one of the most popular tools that can be used to identify vulnerabilities in a server.

3- Nikto:
Nikto works like Nessus, but the thing about this tool is that if an intrusion detection tool is used, the hacker who have used this tool can be easily detected.

4- OpenVAS:
This tool is also used to identify server vulnerabilities.

5- Metasploit:
How to work with this tool is very simple and even a novice hacker can easily use it in order to access vulnerabilities in a server.

6- HTTrack:
This tool allows a complete analysis of a server.

7- Maltego:
These tools are very suitable for analyzing servers and can provide other possibilities for hackers.

8- Netsparker:
All programs and services on the server can be scanned by this tool.

9- ScanMyServer:
This tool can be used for free in order to find out the security holes.

-The main stage is hacking, in which after collecting data and finding vulnerabilities in a server, the hacker begins to implement the things that must be done in this step, hackers take advantage of the weaknesses which they have identified through existing tools and use them in order to hack, there are different kinds of attacks that hackers use, which we will mention some of them below.

Types of hacker attacks on servers:
- injection attacks:
One of the attacks that hackers use is injection attacks , in which hackers use malicious code that causes damage to the server.

- DOS attack:
Denial-of-service attack is a type of attack that affects the services provided by the server and causes errors in it, which is one of the attacks that hackers use a lot and affect the servers.

- Website defacement:
Through these attacks, hackers modify the server and replace the sites on the server with one of their own servers, and by using this attack, they try to achieve their goal.

- Phishing Attack:
It is a type of cyber-attack in which hackers send a fake mesغير مجاز مي باشدe, endangering all user data.

Through these attacks, hackers can easily access people's information as well as online accounts and cause malicious damage to the system, and hackers may gain a lot of money through the information which they have obtained about the user's credit card, or make the most of other important information they have obtained related to a particular subject, which is the main reason that all users should be fully aware of phishing, so that they can take care of themselves and ensure the security of their information . Phishing attacks have different types, including phishing email, deceptive phishing, spear phishing, vishing, pharming attacks, each of which has lots of details and hackers use them to hack various things such as servers, etc.

In general, hackers can eventually edit the information and content on the server through the items we have mentioned, and by changing the valuable contents in it into malicious contents, cause a decrease in the reputation of sites on the server, it is also possible that hackers put malicious links in the content while editing, which also reduces the value of existing content as well as the credibility of the site, another step that may be taken by hackers to hack servers is that if a user visits a site that has been manipulated by hackers, malware is installed on their system and the hacker can access a lot of personal and important information of users through it.

When sites lose their credibility, their owners try to find out the reason which is causing their sites to lose their credibility, and they will eventually find out that the problem is with the server and hackers have been able to hack the system through the server, at this time site owners can complain about the server that hosted their site, all of which finally will cause a lot of damage to the owners of sites and servers, as a result, the security of all items must be observed properly, and before security is affected by black hat hackers, etc., the owners of the servers can get help from white and red hat hackers in order to protect their information and check the security of the server, so that if there are security holes, they can quickly check and fix them properly.

Last word:
Servers have a great impact on the speed of loading the site, etc., nowadays, time is of great value to all users, as a result, sites that have a high speed on the search engine results page, can achieve a high ranking and ultimately attract organic traffic to their sites, eventually sites use servers to increase their speed, and if these servers are noticed by hackers, and they have many weaknesses after scanning, it can cause a lot of problems for users, so it is necessary to remember all the points related to server hacking and try to choose a secure server for your site with complete mastery of these issues in order to protect your important information from being stolen.

In order for local applications to have access to the web, special settings must be made in their design so that they can finally access the web. This article teaches you how to create a class and access the web through the created classes. If you want to know how to create classes in the application and access the web through classes, it is recommended to follow this tutorial.

In this section you will learn:
- How to use NuGet Package Manager to add Newtonsoft.Json to Xamarin.Forms projects.

- How to create classes that also have access to the web.

- How to use the classes created to access the web?

The requirements for doing this training are as follows:
- Install the latest version of Visual Studio 2019 on the system

-  Install the latest version of Mobile development with .NET on the system

Learn how to add Newtonsoft.Json to Xamarin.Forms projects with NuGet Package Manager using Visual Studio
1- Open Visual Studio.

2- After opening Visual Studio , you need to create a new black Xamarin.Forms app.

3- Choose a name to create. The name chosen in this article is WebServiceTutorial.

4- It is better to be careful in choosing names for the projects and classes created.

Note:
The name chosen for the project must be the same as the name chosen for the solution, so choose the solution name WebServiceTutorial.

5- After naming, you must make sure that the system and application support the .NET Standard mechanism for shared code.

This mechanism is used to share code written in Xamarin.Forms with the C # programming language. If your system and app do not support this mechanism, it cannot have multiple outputs on multiple platforms at once. Therefore, in order to be able to have multiple outputs on several different platforms at the same time, you must be sure that your app and system support this mechanism.

6- Right-click in the Solution Explorer section of the WebServiceTutorial project.

7- Select Manage NuGetPackeges.

8- In the NuGet Packages Manager section, select the Brows tab.

9- Search for Newtonsoft.Json, then install it and add it to the project.

10- Build a Solution to ensure there are no errors.

Learn how to create classes in Xamarin.Forms that also have access to the web using Visual Studio
1. In the Solution Explorer section of the WebServiceTutorial project, create a new class called Constants and add it to the project.

2. Replace all the code listed below with the code in the Constants.cs section.

namespace WebServiceTutorial
{
public static class Constants
{
public const string OpenWeatherMapEndpoint = "Error! Hyperlink reference not valid.";
public const string OpenWeatherMapAPIKey = "INSERT_API_KEY_HERE";
}
}

By entering the above code, you define two constants. OpenWeatherMapEndpoint is an endpoint versus web request, and OpenWeatherMapAPIKey displays your personal API key for OpenWeatherMap.

3. In the Solution Explorer section of the WebServiceTutorial project, create a new class and name it WeatherData and add it to the project.

4.  Replace all the codes listed below with the codes in the WeatherData.cs section.

using Newtonsoft.Json;

namespace WebServiceTutorial
{
public class WeatherData
{
[JsonProperty ("name")]
public string Title {get; set;}

[JsonProperty ("weather")]
public Weather [] Weather {get; set;}

[JsonProperty ("main")]
public Main {get; set;}

[JsonProperty ("visibility")]
public long Visibility {get; set;}

[JsonProperty ("wind")]
public Wind {get; set;}
}

public class Main
{
[JsonProperty ("temp")]
public double Temperature {get; set;}

[JsonProperty ("humidity")]
public long Humidity {get; set;}
}

public class Weather
{
[JsonProperty ("main")]
public string Visibility {get; set;}
}

public class Wind
{
[JsonProperty ("speed")]
public double Speed {get; set;}
}
}

By entering this code, you define four classes that are used to model the recovery of JSON data.

5. In the Solution Explorer section of the WebServiceTutorial project, create a new class called RestService and add it to the project.

6.  Replace all the codes listed below with the codes in the RestService.cs section.

using System;
using System.Diagnostics;
using System.Net.Http;
using System.Threading. Tasks;
using Newtonsoft.Json;

namespace WebServiceTutorial
{
public class RestService
{
HttpClient _client;

public RestService ()
{
_client = new HttpClient ();
}

public async Task GetWeatherDataAsync (string uri) {
WeatherData = null;
try
{
HttpResponseMesغير مجاز مي باشدe response = await _client. GetAsync (uri);
if (response. IsSuccessStatusCode)
{
string content = await response. Content.ReadAsStringAsync ();
weatherData = JsonConvert.DeserializeObject (content);
}
}
catch (Exception ex)
{
Debug.WriteLine (" tERROR {0}", ex. Mesغير مجاز مي باشدe);
}

return weatherData;
}
}
}

By entering this code, you define the GetWeatherDataaAsync method. This method uses the HttpClient.GetAsync method to send a GET request to the web API. The web API sends a response that is stored in the HttpResponseMesغير مجاز مي باشدe object. The response contains the HTTP status code, which is used to determine if the HTTP request was sent successfully.

If the request is successful, the web API will respond with HTTP status code 200 (OK) and JSON response.

7. Build a Solution to ensure that there are no errors.

{
if (! string. IsNullOrWhiteSpace (cityEntry.Text))
{
WeatherData = await _restService.GetWeatherDataAsync (GenerateRequestUri (Constants.OpenWeatherMapEndpoint));
BindingContext = weatherData;
}
}

string GenerateRequestUri (string endpoint)
{
string requestUri = endpoint;
requestUri + = $ "? q = {cityEntry.Text}";
requestUri + = "& units = imperial"; // or units = metric
requestUri + = $ "& APPID = {Constants. OpenWeatherMapAPIKey}";
return requestUri;
}
}
}

The OnButtonClicked method is executed when the Button is hit.

5- Press the start button or the Ctrl + F5 key combination to see the result of the applied changes.

The requirements for doing this training are as follows:
- Install the latest version of Visual Studio for Mac on the system

- Install the latest version of support platform for Android and iOS on the system

- Install the latest version of Xcode on the system

Site security is of a great importance and if all the points that are necessary in order to keep a site safe are not followed properly, the information that you have in your system and also your site can be easily stolen by a hacker, there are many of them who are looking for insecure sites, so that they can easily penetrate it through the security holes exist on the website and reach their desired goal, interestingly, the number of these people is increasing day by day, and therefore users' have a huge concern which refers to the security of their site that this feeling of insecurity is the increase of number of hackers, and the question of which is constantly raised in users minds is that who is responsible for security of the site? What are the duties of this person? And lots of other questions that these people are looking for the answers of them on the Internet in order to get desired results, on the other hand, there are people who do not take the security of the site seriously at all, and constantly think that if they have not been hacked so far, then their site has a high security, but this is not a true opinion, and they should take the possibility of not being noticed by hackers into consideration, so it can be a good reason for not being hacked until today, and if a hacker decides to hack their site, he/she can easily implement malicious actions on them, and cause many problems for this people, before giving the answer of the popular question that who is responsible for site security? It is necessary to have an overview of site security.

What is site security?
In simple terms, site security means any action taken to protect a site from being attacked by hackers and cyber attacks, the measures taken to increase the security of the site are different, and due to the important information available on the site as well as the budget, different types of methods should be used in this direction.

Who is responsible for website security?
The security of your site is your own responsibility, people may suggest that you can increase the security of your site with a limited budget, but this is definitely impossible, and if you want to increase the security of your site as good as possible, you need to spend a lot of time and energy in order to a reach your goal.

You can even entrust the security of your site to companies that have specialized people in this field, and you have to pay a lot of money to them, but a disadvantage is that these companies are responsible for the security of many sites, as a result, the security of your site is not the main goal of such companies, so your site may not be much secured.

If you want to know more about the person who is responsible for site security, you need to answer the question of who gives more importance to your site and makes profit out of the success of your site, which the answer of all these questions is you, because you are the one who can definitely help increase the security of your website by learning tips to secure your website, which we will mention in more detail below.

Tips regarding site security:
- Back up your website:
One of the ways you can increase the security of your site is to make a backup of the information of site, to do this, you need to make several backup copies of your site and ensure the security of all those backups, so you need to be able to use them and not lose your site at once due to hacking attacks.

The reason we emphasize that you should not make a single backup and the importance of making several backups, is that if your site is attacked by hackers, it may be through malware and if a copy replaced the backup, it will be attacked again simply, eventually you need to make more backups and keep them in a safe place, so that people who want to damage your site will not be able to access those backups.

- Monitor your website closely and regularly:
Maintaining the security of a site requires regular monitoring to realize the things that happens on the site, and if you feel something suspicious that has happened on your site, you should quickly check everything, so that it will not be damaged seriously, and you can increase your website security and prevent hackers from achieving their goals.

- Install a powerful antivirus on your system:
If your system is infected with a virus, it means that hackers can infect your site with just one move, so you need to install a strong antivirus and update it regularly in order to keep your site secure.

- Use the website firewall:
The firewall specifies that who can access the site, and who cannot access it, using a firewall can help you maintain your site security and block hacker’s way from entering your site, in addition to the things we have mentioned so far, you need to follow other tips in order to be able to compromise the security of your site, but how can hackers endanger the security of your site? Let us give you a brief explanation in this regard.

What do hackers do to endanger the security of the site?
- Malware:
One of the ways that hackers use to compromise the security of your site is through malware, there have been many reports of hackers using malware, in which case hackers create malicious software that endangers the security of your site if it is used by site owners, as a result, you should be aware of not choosing any kind of software for your system and only provide the one you need from reputable sources on the Internet.

- DDoS attacks:
These attacks are also very common among hackers which target and disrupt site traffic, even in some cases, the site owners ask for money to fix the site traffic disruption and return it to its original state.

- Spam emails:
Surely you have encountered a person who has received spam emails, so you know the results, our suggestion to you is not to open suspicious emails at all, so that hackers cannot access the system as well as the site, there are many ways that hackers can use to infiltrate your site, 3 of which will be mentioned briefly in order to make you realize the dangers threaten your site and take your site security more seriously.

Why should you take action to secure your site?
- If your site is hacked, your site’s credibility will be significantly reduced:
Imagine that people want to use your site services and eventually find out that your site has already been hacked, so do you think that it is possible for them to trust your site? Do they enter their personal information on your site?

The answer to this question is definitely no, and people will never choose your site in order to meet their needs.

- In case of a cyber-attack, the غير مجاز مي باشدt of troubleshooting problems of the site is very high:
You may think that you should not spend your time on the security of your site and if hackers attack your site, then you will take the necessary action, but this is a wrong idea, because the غير مجاز مي باشدts that are required in order to increase the security of a site , are certainly much lower than the غير مجاز مي باشدts that are required to solve the problems that arose after the hacking attack.

- Cybercriminals target small businesses:
The smaller a site is, the easier it is to hack, and hackers are constantly looking for easier ways in order to achieve their goal, so try to increase the security of your website and improve your acknowledgement about site security in order to take the necessary steps with more awareness.

Last word:
The security of your site is your responsibility and in this way you can get help from companies that specialize in this field, but never forget that you need to monitor everything yourself and never leave everything to others and only get help from them in this way.

The security of computer systems has become an important issue today and users are looking for the best ways to protect the site against malicious programs as well as hackers, in this way, they may use various methods such as using safe passwords, constantly updating the system, using antivirus, not clicking on spam emails or other things that one of the most effective things they can do is to use a firewall.

In the following, we will discuss how effective the use of firewalls is, and we will also examine whether hackers are able to pass the firewalls or not.

What is a firewall?
In fact, firewalls are network security systems which control traffic flow between the Internet and the private network, it also protects a system from illegal access and provides high network security for the system, there are three basic types of firewalls, each of which are going to be briefly described below.

A number of different types of firewalls:
- غير مجاز مي باشد Server Firewalls:
This type of firewall is a network security system that can protect network resources well and provide high security in the connection between internal servers and the existing servers on the Internet.

- Stateful Inspection:
These types of firewalls can also provide high security in the network and use the smartest methods to block unauthorized traffic and ultimately provide high security for the system.

- Packet Filters:
These types of firewalls, compared to other types, have less ability to provide security for the network and analyze all the data that enters or exits the system, and in case of a suspicious act, the data is not allowed to enter the system.

In fact, these types of firewalls are suitable for small networks and do not have a high ability to increase network security for large companies.

The things that firewalls protect the system and information from:
There are different types of firewalls, and each of them protects the computer system against different factors, firewalls detect unauthorized traffic and prevent any further damage quickly.

- They allow the internal attacks to be minimized.

- Firewalls are one of the most suitable tools that can prevent the entry of malware and protect the system against such malware, in addition to the things mentioned above, firewalls have other capabilities, and we are going to mention some of the best firewalls in 2021 below.

The Best firewall of 2021:
- Bitdefender Total Security:
Bitdefender Total Security is one of the strongest security that protects the system against viruses as well as malware, through this firewall, a wide range of items that are necessary for system security can be achieved, by providing one of these firewalls, you can protect information on five devices, for example, you can use the same type of firewall that you have provided for both your personal computer and your mobile device.

Many users use Bitdefender Total Security because of the reasonable price of this firewall and also the fact that it can provide a wide range of security protections .

- Webroot AntiVirus:
This firewall, occupies only a small amount of space, after being installed on the system, and due to its low volume, it takes only a few seconds to install, all users who use this type of firewall give Webroot AntiVirus an acceptable and good score, which has attracted many users to it.

- ZoneAlarm:
ZoneAlarm is one of the best firewalls that requires payment and has many features to use, it should be noted that it also has a Pro version, which has more capabilities compared to the free version of this firewall.

It protects your system against unauthorized incoming and outgoing traffic to the system, in addition to the features which we have mentioned about this firewall, it also has other capabilities, all of which have made it one of the best firewalls available.

- GlassWire:
Among the available firewalls we can mention GlassWire , which is free and also provides many features for users’ data protection, if an unknown device is connected to your system, it will be detected by this firewall and will be reported to you in order to make you aware of this process, so you can disconnect it, if necessary.

In general, if you use this firewall, you can access a wide range of features and keep your information safe from hackers.

- Comodo Firewall:
This firewall, like the previous two, is for free and can control all incoming and outgoing traffic, as a result when a harmful software enters your system, it will quickly block its connection to your system and also alerts you in a case that malware enters your system.

- TinyWall:
This firewall is able to protect the system well against malware and prevent malicious programs from changing Windows firewall settings, using this firewall makes it easier for you to reach your goal while using the Internet without opening pop-up windows and protect your information from hackers, so it prevents your personal and important information from being stolen.

Can the firewall be hacked?
So far we have mentioned a lot of points about firewalls, but you may be thinking about the common question which is whether profiteers can hack firewalls or not, the answer to this question is yes, hackers can bypass the firewall through various ways and gain access to the information, as a result, you can do the following to protect your information more and more.

- Enable multi-factor authentication:
As a result, you can keep your information safe if hackers bypass your security tool , if you use multi-factor authentication, you will make it more difficult for hackers, you should also be very careful in choosing a strong and safe password which is hard to guess in order to make the process as hard as possible.

- Perform penetration test:
By performing a penetration test, you are able to identify the security holes that exist in your system or in the firewall that you use, as a result you can finally choose the appropriate solutions to repair the security holes, and as you know hackers use the same security holes to infiltrate various systems, which you can prevent further malicious events by performing a penetration test.

- Get help from several firewalls at different levels simultaneously:
As we mentioned in this article, each firewall has different capabilities, therefore, if they are being used in combination, can greatly increase system security , each firewall is not strong enough to withstand all attacks which are being occurred by hackers, so several firewalls must be used at the same time in order to achieve the desired results.

In fact, it is possible for each firewall to have security holes, and using another firewall at the same time will eliminate the existing security hole.

- Stay on the top of Security patches:
One of the ways to help you greatly increase the security of your system is to use this method which after using it, you can realize how much security of your system has increased and hackers cannot access the information in your system easily in order to achieve their desired results, despite these tips, firewalls can still protect the information in the system against phishing attacks, DDoS attacks, direct physical access and so on, as a result, you should get help from other available features to increase the security of your system.

Last word:
In general, despite all the points we have mentioned in this article, using firewalls can provide a very high level of security for the system , which you should follow the tips in using firewalls to increase security, so that you can reach your goal with more guarantee and prevent any attack by profiteers, in order to fill the security holes you have to implement all the steps mentioned above, in addition to other steps that you have to take for having a secure system, as a result you shouldn’t provide any security holes due to the fact that hackers are always looking for a way even a small hole to enter your system in order to abuse your information and make the most of them in an illegal way which can cause a huge problem for you.

after sending the user request to launch the application , it refers to the resources available on the operating system so that they can launch and launch the application. Applications have user interface layouts that exist in XML files.

Applications available on the Android OS have resources that we will teach you in this tutorial.

Basics of application resources in Xamarin.Android
When an application is created for the Android operating system, the resources related to that application are set by the default Xamarin.Android template.

The files that create the default resources are as follows:
icon:
This file has the default Icon.png for the application icon created.

Main.axml:
This file has the default user interface layout for the created application .

Note:
Android supports the xml format while Xamarin.Android uses the axml format.

Strings.xml:
Creates a string table that is used to help localize Word applications.

AboutResources.txt:
This file is not necessary and you can even delete this file because it does nothing special, it just provides an overview of the level of Resources files.

Resource.designer.cs:
This file, unlike the AboutResources.txt file, is very important and is produced by Xamarin.Android . This file has a unique ID's for each source. In fact, this file was created automatically by Xamarin.Android and will be restored from time to time if needed.

How to create resources and access them?
Creating application resources is a very simple and easy task. Add Strings.xml to the file and project. Once added, Build Action is automatically set to AndroidResource. AndroidResource setting is done by Xamarin.Android tool. Doing so will allow you to properly compile the Xamarin.Android tool and embed the resources into the APK file.

Note:
If Build Action is not set up properly on Android Resource, all existing file in the APK will be removed and no attempt to set or upload files will be effective. In this case, you will encounter a runtime error and eventually the application will crash.

Unlike Android, Xamarin.Android is not strict and supports all lowercase and uppercase characters. And you can easily use uppercase or lowercase letters when naming them because Xamarin.Android does not give any error for using uppercase and lowercase letters.

Note:
When naming sources to separate if you use dashes or spaces are not supported and processed. You can use the underline to separate them.

How to access resources added to the file?
There are two ways to use the resources added to the file:
- Use XML files
- Coding to access resources

Access to added resources through coding
To access the available resources by programming method , we must assign a valid and unique identifier for each resource. The unique identifier assigned to each resource is an integer that will be defined within the Resource class.

The code inside the Resource.designer.cs file gives access to the resources, the code inside the Resource.designer.cs file must be as follows to be able to access the added resources:

public partial class Resource
{
public partial class Attribute
{
}
public partial class Drawable {
public const int Icon = 0x7f020000;
}
public partial class Id
{
public const int Textview = 0x7f050000;
}
public partial class Layout
{
public const int Main = 0x7f030000;
}
public partial class String
{
public const int App_Name = 0x7f040001;
public const int Hello = 0x7f040000;
}
}

By entering this code, you are actually assigning a valid identifier to each resource, although the identifiers assigned to the resource are related to the type of resource. For example, when Icon.png was added to the project, the Resource class was updated by Xamarin.Android.

Resource should not be changed manually, as all changes made to it will be replaced by Xamarin. Android .

To access the resources created using the coding method, you can also use the code below:
@ [.] Resource. .

PackageName:
A package whose job is to provide a resource.

ResourceType:
A type of resource that is distributed as described within the Resource class.

Resource Name:
is the name of the source that the source name must be without extension.

Access added resources via XML file

The resources inside the XML file are as follows:
@ [:] / .

PackageName:
A package whose job is to provide a resource.

ResourceType:
A type of resource that is distributed as described within the Resource class.

Resource Name:
is the name of the source that the source name must be without extension.

The code inside the Main.axml file to access resources via the XML file is as follows:
Check if the contents of the Main.axml file are not the same as the code below, replace the code below with the contents of the Main.axml file.

android: orientation = "vertical"
android: layout_width = "fill_parent"
android: layout_height = "fill_parent">
android: layout_width = "wrap_content"
android: layout_height = "wrap_content"
android: src = "@ drawable / flag" />

In this code, ImageView sets the src property to @drawable / flag.

Learn how to set the default resources of applications in Xamarin.Android
Default resources are resources that are not specific to devices and applications , in fact there are specific resources for each application or device that will be selected by default if specific resources are not found by the Android operating system. Default resources exist from the beginning, and if device-specific resources do not run, default resources will run instead of specific resources.

The different types of sources are as follows:
Animator:
XML files are used to describe property animations. property animations for version 3.0 of Android was introduced and launched. property animations are flexible and are a powerful way to produce different types of animations that are used.

Anim:
XML files are used to describe tween animations. tween animations are actually a set of animation commands that are used to make changes to the contents of the View object. For example, rotating and moving images or resizing text in animation uses Tween animations to make changes inside View objects.

color:
XML files that are used to describe a list of colors. Consider an example of changing the color or using the colors in the list, changing the button mode and changing its color. A button can have active or inactive modes, or it can have compressed or non-compressed modes, in which case the color of the button will change as well.

Drawable resource:
In general, it can be said that drawable is a concept used for graphics. Anything related to graphics in the program can be drawable inside. The drawable can be easily compiled within the program, then called by the API or referenced using other XML resources. bitmaps (.png, .gif, .jpg), bitmaps are examples of drawable that can also be resized. Such as state lists and Nine-Patches ...

Layout:
XML files that are used to describe the interface layout, such as an activity or a row in a list.

menu:
XML files that are used to describe program menus such as Context Menu, Options Menu and submenus. Popup Menu Demo and Standard Controls are examples of in-app menus.

Raw:
These are files that are automatically saved in binary type in raw.

values:
are XML files that have simple values. An XML file in the values ​​directory does not define a single source, but several sources.

xml:
are XML files that function similarly to the .NET configuration.

Learn how to set up alternative sources for apps on Xamarin.Android
Alternate resources are resources that are used by the Android operating system in the absence of default resources. If Android is looking for a default source but finds a source that is more accurate than the default source, it will select and run a more accurate source. Of course, if Android does not find an alternative source that is more accurate than the default source, the same default source will be downloaded.

Alternative resources are placed within resource files, such as the default resources, as subcategories of the default resources:

-

Qualifier:
A name used to identify the device configuration. There may be more than one qualifier with one name, in which case the names are separated by a hyphen.

The rules that must be followed when adding Qualifiers to resources are as follows:
- There may be more than one qualifier with a name, each of which is separated by a dash.
- The qualifier may be specified only once.

The different types of qualifiers that are mentioned for resources are as follows:
MNC and MCC:
MCC is used to provide and configure the SIM card while MNC provides the device connected to the network. The values ​​in MNC and MCC are different for other countries and sources. For example, when assigning a qualifier to a country in Germany, the qualifier must be mcc262. When assigning a qualifier to the United States, the qualifier must be mcc310-mnc026. For information on country codes, you can visit http://mcclist.com/.

Smallest Width:
Used to specify the smallest width of the page intended to run the application.

Available Width:
The minimum width of the page that is intended to display the application and the value of this can be changed by rotating the device.

Available Height:
​​​​​​​The minimum height of the screen that is intended to display the application and the amount of this can be changed by rotating the device.

Screen Aspect:
This qualifier is based on the dimensions of the screen, not on the orientation, and does not change with the rotation of the device. The values ​​that can be included in this qualifier are notlong and long.

Screen Orientation:
This qualifier can be changed by rotating the device and the values ​​that are placed in it can be landscape or Portrait.

Dock Mode:
​​​​​​​ is a qualifier that can take car or desk values.

Night Mode:
​​​​​​​ This qualifier is used to determine whether the program is in use during the day or at night. The purpose of this qualifier is to give users the opportunity to use dark or light modes of user interfaces. The values ​​in this qualifier are: notnight and night.

Screen Pixel Density:
Used to specify the number of pixels at a point on the screen.

The values ​​in this qualifier are as follows:
ldpi:
Screen with low density and number of pixels

mdpi:
Screen with medium density and number of pixels

hdpi:
Screen with high density and number of pixels

xhdpi:
Screen with very high density and number of pixels

nodpi:
Resources that have no value

Touchscreen Type:
Used to determine the touch of the screen and the values ​​in this qualifier can be notouch, stylus and finger. The finger is used to specify the touch screen, the stylus is used to define the screen using the stylus, and the notouch is used to specify the non-touch screens.

Keyboard Availability:
Used to determine the type of keyboard used, and its values ​​may change by changing different types of keyboards. The values ​​that this qualifier can take are as follows:

Keys exposed:
In this case, the device has an available and active keyboard, and if there is no software keyboard, the hardware keyboard will be launched.

keyshidden:
In this case, the device has a hardware keyboard, but the hardware keyboard of this device is hidden and of course no software keyboard is active.

keyssoft:
In this case, the device has a software keyboard.

Primary Text Input Method:
This qualifier is used to specify what kind of hardware keys are used for input. The values ​​in this qualifier are as follows:

nokeys:
There are no hardware keys to log in to the app .

Qwerty:
There is a qwerty keyboard.

12key:
There is a hardware keyboard that has 12 hardware keys to enter.

Navigation Key Availability:
Activated when there are 5 directions and of course the values ​​in this qualifier are as follows:

nav exposed:
Navigation and directional keys are active for users to use.

Navhidden:
Navigation keys are disabled for use by users.

How does Android determine which source to use?
In the Android OS, the applications that are produced have a lot of resources and in order for the applications to be launched, they must be run on a source. The number of resources available in Android is high and the question is how the Android operating system determines which source to use.

Android determines the resources bases as follows:
Eliminate contradictory qualifiers:
In this case, if the device orientation is portrait, all directories in the landscape source will be rejected.

Ignore qualifiers not supported:
Not all qualifiers are available for all API levels. If the resource directory has a qualifier that is not supported by the device, that resource directory will be ignored.

 Identify the next highest priority qualifier:
Selects the highest qualifier priority based on the table. Qualifier priority is from top to bottom.

If the Android operating system is looking for specific resources and cannot find them, it will try to find other resources. In this case, the Android operating system may not use the default resources. For example, if the operating system is looking for low-density pixel resources and cannot find them, it chooses medium or high-density pixel resources.

Imagine an application whose resources are as follows:
rawable
drawable-en
drawable-fr-rCA
drawable-en-port
drawable-en-notouch-12key
drawable-en-port-ldpi
drawable-port-ldpi
drawable-port-notouch-12key

This application is run with these resources on a device with the following features and facilities:
Screen density: hdpi
Locale: en-GB
Primary keyboard input method: 12key
Orientation: port
Touchscreen type: notouch

Then, French sources that do not conform to en-GB are removed as follows:
drawable
drawable-en
drawable-en-port
drawable-en-notouch-12key
drawable-en-port-ldpi
drawable-port-ldpi
drawable-port-notouch-12key

All resources that do not comply with the en-GB language will be removed.

After deleting resources that do not comply with the en-GB language, the available resources are as follows:
drawable-en-port
drawable-en-notouch-12key
drawable-en-port-ldpi

Orientation is then performed and all directories that do not match the page orientation are removed:
drawable-en-port
drawable-en-port-ldpi
Then, directories that do not match the page density are removed:
drawable-en-port-ldpi

In this way, the Android operating system selects the appropriate source to use.
