If important data is corrupted, it can cause irreparable damage to individuals as well as institutions, so it is necessary to protect them from being damaged, in the field of data protection , in fact, there is a need to ensure that if data is lost, you can recover the data again. It is also necessary to provide security and privacy for all your data , in general, data protection is an essential issue, which is why we are going to discuss it in more detail and mention the important points.
What is data protection?
Data protection is the protection of privacy by regulating the processing of personal information, as well as identifying individuals to protect data by defining their duties and having control over their work.As we mentioned earlier, data availability in case of a data breach is one of the principles of data protection and another important issue in this field is data management.Data management itself has two fields including data lifecycle management and information lifecycle management, which we are going to discuss in more detail below.
- Data lifecycle management:
In this field of data management, all important data in a system is in the way of storing it online as well as offline.
- Information lifecycle management:
In this cycle, the information is protected against errors that may occur in the program, such as virus attacks, technical problems in the device, malware , etc., in order not to damage them, new tasks may be added to the management every day, and the ultimate goal is to protect the data in the best possible way.
Which methods were used to protect data in the past?
As you know, when the data is stored, some steps needs to be taken in order to protect it, the best ways for data storage are offline methods, in the past, many organizations, tried offline method in order to store their data through which they copied data to the tape cartridge machine, and they would eventually protect that tape.Storing data on another computer system is something that you have to be more worried about because your data is more endangered, due to the fact that protecting your data from hacking attack would be much harder, even though having access to the tapes may be a slow process, it is the best method and there won’t be any risk of attacking the network and losing data backup.

Gamers usually sit on the game chair for a long time. A professional gamer may sit in a chair for about 10 hours a day. Therefore, having a comfortable and standard chair in which the principles of ergonomics are well observed; it's too important. The chair should be adjustable so that the person can easily sit in a comfortable position relative to his computer.Characteristics of gaming chairs allow the gamer to fully enjoy the game.A chair has certain parts, each of which must have characteristics in order to be accepted as a good chair.
Comparing a play chair with an office chair:
a gaming chair , the back of the chair is long and extends to the head. In addition, the back and seat of the chair are serrated and keep the body firm and stable. There is no holding position in a normal chair and it can be said that it is difficult to sit properly on it for a long time.Another difference between game chairs and office chairs is in their design and color. Game seat designers try to use colorful designs to make these seats look like a sports car. This chair may be pink or bright red. Of course, these chairs have a good variety of colors and game enthusiasts can easily match it with their play space. While in other chairs, designs usually do not fall out of the category of public furniture.Also, in game chairs, unlike ordinary chairs, a more durable metal frame is used so that heavy users can use it for a long time without worry. In general, these chairs are wider than ordinary chairs.
In the following articles, the expected features of each part of the seat suitable for the game will be stated.
Seat back:
One of the characteristics of gaming chairs is the long back of it. Seat back is of particular importance. Because it can help keep the back in a straight and upright position and prevent back pain.The back of the chair should be at a suitable height that can support your pelvis, spine and back well. Also, its slope should be adjustable. Having lumbar cushions and head cushions are useful for optimizing the backrest and helping to sit better. Leaning the head back makes the weight of the head split on the neck, making it easier to look at the monitor while lying down.

7 layers of security:
- Information security policies:
Information security policies is one of the main layers of security and if the points related to this layer are followed by the owners of sites, web servers, etc., users will come to the conclusion that you care about the security of their information as well as the security of their system, as a result they will gain a positive user experience.In this layer every effort should be made in order to be able to effectively protect the available information, this layer of security has 3 main types, organizational (or Master) policy, system-specific policy and issue-specific policy.
With the increasing development of science and technology in today's world, the ways of communication and data transfer have changed and technology is evolving day by day, as a result of which security and privacy are becoming more and more important, each of the terms, security and privacy has a huge world as well as many details, in this article we are going to discuss security and privacy in ICT .
What is information and communication technology (ICT)?

As you know, there are many programming languages that can be used in order to implement various features in a web or application, among all the languages, one of the most popular is JavaScript, many programmers use it because it can eventually be used to make the user interact with the content better which is one of the most important factors in attracting users to your websites , there are several features in this language that you can learn by mastering each of them in the best possible way, which we are going to examine variables and data types in JS.
What is JavaScript?
The abbreviation for this language is JS, which allows you to use it to create dynamic content on the web, which has a very high interaction with the user, also with the help of this language, even very complex features can be easily implemented on the web, and the point that should be mentioned here is that any program written in JavaScript is known as a “script”.JS can be run on both browsers and servers, there are JavaScript engines in various browsers, which are actually embedded by JS scripts and can be used to convert the script into a language that can be recognized by various devices.
JavaScript Variables:
In order to be able to store different amounts of data, you need to get help from it, which in order to master this, we suggest you pay attention to the following example.
<! DOCTYPE html>
<html>
<body>
<h2> JavaScript Variables </h2>
<p> In this example, x, y, and z are variables. </p>
<p id = "demo"> </p>
<script>
var x = 7;
var y = 8;
var z = x + y;
document.getElementById ("demo"). innerHTML =
"The value of z is:" + z;
</script>
</body>
</html>
Let and const:
The case which we have mentioned at the beginning was the only way that have been used in order to store data values until 2015, but now other ways are being used instead, including let and const.
The variety of websites is increasing day by day and different users have the right to choose one of them, one of the factors that affect the choice of users is the layout of a site due to the fact that when the site layout is attractive , it causes the users to choose it among others, there are various elements which are effective in creating a page, and in addition to the existence, their arrangement is of a great importance, and you must choose where each element should be placed very carefully, in the following, we are going to pay more attention to this issue.

This is another type of link that, as the name implies, includes links that different users have visited.
- a: hover:
In this type, the users hit the link with their mouse, but they do not click on it.
- a: active:
It refers to the exact time when the user clicks on the link.It should be noted that if you wanted to use multiple link modes in CSS at the same time, a: visited must be followed by a: link or a: active must be followed by a : link, a: visited and a: hover.
There are several sites that users can use on a regular basis in order to get the answers to their questions, each of which has different appearances, which is what makes them attractive to different users, such as the virtual world where the user chooses a store, out of hundreds shops, due to the attractiveness of the shop design , as a site owner, in order to create an attractive design for your site , you need to increase your level of knowledge about CSS and learn the ways of choosing an attractive background for different pages, or you can use a readable and appropriate font in order to increase your site traffic , but before that we need to give you a brief and general explanation about CSS itself.

This method should be used when a page has its own unique style, so that you cannot make a big change to it, in this case you can easily apply the desired changes through this method.
Play designing has a very important role in technology and entertainment today. In this article, we want to talk to you about the tools and game courses and tell you how you can increase your knowledge in game development by using the various courses that exist in this field. Note that in general there are many steps and actions in the field of designing a game . At the elementary level, you should try to master the skills of programming, getting acquainted with Photoshop software, having a lot of motivation and energy, and passing the game programming course, game design course, and game art course so that you can finally, design and produce a game. Note that there are different courses and stages for game making that you can use according to your taste from any of these courses that are available in various levels and sites to be able to develop your skills in making and producing games. These skills are held in many different types and different courses for those who are interested, and you can find the institute or site you want by researching in this field and spend your courses in them.
Steps to game development
After you have chosen your course and enrolled in the institute of your choice to take gaming courses, it is better to know some tips about the game programming process so that you can increase your knowledge in this field. In the following, we intend to fully name the stages of designing a game for you to more familiar with this stage.
First, raise your information
In the first step in designing game , you should be familiar with some of the terms that exist in this field so that you can have a better understanding of the purpose of game development. You need to have answers to these questions such as why we play, how many games there are, what the style of computer games is, what hardware is needed to run the game, and who the game maker is, when you can answer these questions, you can grow higher in the field of game coding and its goals. Note that games today are not just entertainment, and the gaming industry has the potential to become one of the largest and most lucrative industries in the world, so you should try to get all the information you need about gaming so you can have a comprehensive and complete view of the world of games and designing the game so that you can be more successful in this field and can produce appropriate games.
The second step is to introduce the resources
Before you start making games , try to get comprehensive and complete information about playing methods. Try to participate in different workshops for gaming so that you can see the training required for gaming. One of the different and appropriate resources to get help in gaming is the Internet. You can learn anything you want on the internet. When playing games, if you have a problem, try to search all your questions on the Internet so that you cannot only add to your knowledge but also solve your problems. Note that not everything that is said on the Internet is true, so try to use the highest quality sites and make sure that the information you receive is correct so that, God forbid, there are no special problems for you in this area and you can build your own game without any problems. There are also various articles in this field that you can play according to these items.
The third step is to introduce the steps and tools of game designing
After you have mastered the basics of gaming, the third step you should have a complete view of the game you are designing . For example, you need to specify your goal of producing the game , the required and available budget and time, form your team and document, choose the game engine, and test the market. So, after you get the comprehensive information about the designing game, in the third step you have to figure out all these issues for yourself to understand what you are going to do. You need to define your purpose for making the game, for example, some games are made for material, educational, experimental, etc. purposes so you must always have comprehensive information about the game you are making. Once you have defined your goal, you need to know how much budget and time you have to produce, and then you need to determine your team and get help from people who specialize in these areas, and by choosing the right game engine , build yourself a game with the highest quality.
It should be noted that the search process can be different in different sections. In this case, the search results can be displayed to the user from the server, application , system, device, etc. Therefore, the user can easily perform the search operation according to his needs and then receive the related results. In this part of the tutorial, we want to talk about searchview android and search operations.
searchview android is another widget that exists in Android and the user can use it to search for one or more phrases and view the results there. searchview android is actually a bar that is used to perform the search process, in which the user searches for the words or phrases he wants there and sees the results.1- I create a project in Android Studio and name it SearchView as desired.2- The type of activity used in this training is Empty Activity.3- It should be noted that the language required for this project is Java.4- In the activity layout, we add a ListView and SearchView.5- The codes that should be in the activity_main.xml section are as follows:
