Developers do their best to be able to design sites and applications that different users can use in the best possible way and ultimately gain a positive user experience, for programming , there are various languages, including JavaScript, which is very popular among programmers and many of them use this language to do their work, for instance, with the help of it, you can enter a command in which all the first column is multiplied by the second column, and by entering this command only once, all tasks will be done, we are going to explain this part later, but before that we need to give a brief explanation of JavaScript.
What is JavaScript?
It is known as JS, and it is very popular among programmers which can be used for server-side programming, mobile applications , games and desktop applications, and allows users to have a better user experience while using any program which is written with this language, these days, almost all browsers support this language, but if they are disabled, the content or functionality of the web page may be limited or unavailable.In other words, if a website does not use this language despite the importance it has, users will not be willing to use that site in order to meet their daily needs, and it is necessary to use this language in order to create better interaction with users, so that you have to get help from it in order to create a dynamic page which is able to attract lots of users’ attention day by day.
JavaScript Function Definitions:
The function keyword is used to describe the various functions that exist in JS and can be called in different ways, which we are going to discuss below.
In general, functions in JavaScript have two main types, which are as follows:
- function declaration- function expression
Function declaration:
These functions are not executed immediately, in fact, they are stored for later use, so that you can use them whenever you want, as you know, in JavaScript, semicolons are used to separate executable expressions, here consider the following example:
<! DOCTYPE html>
<html>
<body>
<h2> JavaScript Functions </h2>
<p> This example calls a function which performs a calculation and returns the result: </p>
These days, online and offline games have become one of the main entertainment for users, and they spend a lot of time to earn different points in order to win in these games, due to the great difficulty of earning points and various rewards in games, especially online ones, a large number of users tend to be able to achieve many points faster and without much effort, so they choose cheating as a way to achieve their goals, which is considered as a bad choice in real life, but while playing various games , especially online ones, cheating becomes an attractive topic for players, in this article, we are going to discuss whether it is possible to hack them with a cheat engine or not.
What is an online game?
It has a lot of fans among different users due to the fact that these kinds of games run on Internet networks, they have the ability to run on a variety of platforms and operating systems, from Windows to game consoles and mobile phones, with the creation of online games , the world of games has changed entirely, and the ones who were the fan of computers, turned to such games and spent many hours throughout day and night playing them.Through these types of games, it is possible that the users compete with even more than one competitor, and obviously, the more possibilities that the game can provide for the user, the more attractive it will be, of course, hacking offline games is much easier than hacking online ones, due to the fact that they do not have much encryption in their information, which is the reason why it is easier to hack them, there are some programs which are created in order to hack games and provide players with a source of coins, points, etc., in the following, we are going to give a brief explanation about the cheat engine, then we can examine the issue of whether it is possible to hack online games in the Android operating system or not.
What is a cheat engine?
The cheat engine allows you to gain access to all the data stored in memory and make changes to them if you wish, in other words, the cheat engine is a tool for scanning memory, as a result, you can change information in games such as number of lives, energy, equipment, points, etc., with the help of it, for instance you can gain many points very quickly without much effort.
Can online games be hacked using a cheat engine?
Android operating system has lots of fans and there are many games in this operating system, each of which has its own fans, the question that may come to users’ mind is that whether they can gain points, equipment, etc., with the help of cheat engine or not, in fact, all game and player data is stored on online servers, and they are also called server-side games, so it is not possible to hack this type of game with the help of cheat engines, in fact, cheat engine is one of the most popular programs that various users use in order to cheat in offline games, with the help of this program, you can manipulate the internal resources of various games, and it allows users to change the apk file of any program.
Many users these days meet all their needs through different sites or there are many users who spend a lot of time playing different games, in all these cases there must be a feature that can attract them to those websites in order to choose them from many apps and sites out there, one of the things that has a great impact on attracting visitors is that users should be able to interact with the program as well as the web , this issue is very important, and you can see the impact of this issue on increasing the site ranking on the search engine results page which we have mentioned the importance of it in the SEO topics on our site, so that you can decide how much you should care about this topic if you want to create a site .There are several factors that can help in this regard which help you design a site that interacts well with visitors, one of these factors is the use of JavaScript programming language , this language is very popular among different programmers, which we are going to discuss later, as you know, you can create static pages in browsers and web pages with the help of HTML and CSS, but in order to turn them into a dynamic page and a page which the user can interact with, we must use JavaScript, in fact, any step that should be taken will be executable through it, in the following section, we are going to give a brief explanation of the mentioned factors.
What is HTML?
It stands for Hyper Text Markup Language , which is actually a language that is often used in the design of web pages , and in fact in this language all the code is converted to HTML and displayed by the browser.
What is CSS?
It stands for Cascading Style Sheets, in fact, it describes how HTML elements are displayed on various sites, simply put, if you consider HTML as the skeletons of a human body, CSS is actually its flesh and skin which ultimately make up a human appearance, it can be used to control the layout of multiple web pages at the same time, it actually makes the web page more attractive which encourages the users to use the website and introduce it to their friend due to the positive user experience they have gained.
What is JavaScript?
The abbreviation for this language is JS, it is a kind of language which allows you to use it in order to create dynamic content on the web , which ultimately help you create a high interaction with the user, also with the help of this language, very complex features can be easily implemented on the web.It should be also noted that any program which is written in JavaScript is known as a “script”, this language can be run on both browsers and servers, there are JavaScript engines in various browsers, which are actually embedded by its scripts and can be used to convert the script into a language that can be understood by different devices.Consider the following example:
This word is a general word which means that multiple views are used.Pane actually means multiple views. Of course, composite views that consist of several views are displayed according to the size and capacity of the screen. It should be noted that if there is not enough space to display multiple panels or composite views, only one view or one panel is displayed. In this part of the tutorial, we want to tell you about Fragments in the Android operating system , it is recommended that you follow this article.
What is a Fragment?
Fragments are independent components that can be used by any activity. It should be noted that fragments encapsulate all the necessary capabilities, so it is encapsulation that is easy to use in activity and layout.Although the fragments are inside the text of the activities, they also have a separate life-cycle and user interface. Of course, it is possible that Fragment Hubs are below the user interface and it is possible to define them without the user interface. Examples of fragments without a user interface include a headless fragment.
How to access Context
It should be noted that fragments are not below the Context class. Because fragments are not under the Context class, it is best to use the getActivity () method to access parent activities as well.
Advantages of using fragments
Using Fragment makes it possible to reuse components in layouts. In other words, fragments make it possible to reuse components in the layout. For example, you can define single-frame layouts for phones and multi-frame layouts for smartphones and tablets. Fragments on Android smartphones can be defined to support both landscape and portrait orientations.This is why fragments can be easily added or removed dynamically to the activity.An example for this section is that all the activity items in the tablet device are on one page, and in order to be able to access the activities, we can select the desired item from the same page. But in order to be able to access items on mobile smart devices , we must select the detail screen to make the page wider and be able to select the item we want.For example, suppose you have two fragments, one of which is main and the other is detail. Also consider that you have two activities, one of which is main and the other is detailed. It is noteworthy that in the tablet smartphone, the main activity consists of two fragments, while the smartphone devices have the main fragment in the activity.
How to support screens of different sizes using fragments?
To do this, you can define fragments of each activity inside the layout file, which is called static definition file definition. If we define them when they will be executed, they will be called dynamic definition.In order to be able to display different fragments inside the screens based on the available spaces, you must use the activity that displays two fragments on smartphones and tablets.
Server side games have a lot of fans and as you know, many users are interested in these kinds of games and have a great desire to play them with their friends even if it takes many hours, users are generally trying to score points faster in the game in order not to fall behind other competitors, as a result, it is possible that they feel the need of hacking some games, but hacking a number of them is so hard or even impossible.
What is a server side game?
This type of game is available to different users in different ways, and they can play it with their friends as a team on the web, in fact, in these games, information is transferred from the computer which the users are playing with, to the server, where it is processed and then the processing result will be sent back to it, thus it seems these types of games have high security and the server shows accurate information to the player.
Game server types:
Game servers have two different types, which we are going to discuss in the following.
1- Dedicated game server:
As the name implies, these game servers are dedicated, so you have to pay a lot of money in order to use them, the important point about these game servers is that if you use them, they will give you more bandwidth and better performance, additionally, these game servers are more suitable for group games, and they will provide you with round-the-clock support, so you can get help from them in any case.For multiplayer games, this game server is a good option, but if it is a simple game, you do not need to pay more money, and you can prefer to use a less expensive game server.
2- Listen Server:
These game servers are similar to dedicated game servers, but in fact you are playing on a public host and a shared framework, and your teammates will be chosen accidentally, and you cannot choose them by yourself, the features that this type of server provides to users are far less than the dedicated game server, for instance, users may encounter slowing down while playing game or other problems which all of them refers to the connection of many users to a game server at the same time, in the dedicated game server, as we mentioned before, more bandwidth is provided to the user, but in listen server, low bandwidth is provided, and it may be impossible for a large number of players to connect at the same time, so you cannot work as a group, as a result, you are not able to play with your friends.
Is hacking server sided games possible?
Users are very interested in server side games , and one of the most common questions in their minds is that whether they can quickly gain in-game rewards in order not to fall behind their competitors or not, it seems very difficult to hack server-side games, and in some cases it can be impossible to hack these types of games.In these games, there are two sides, one of them is the server and the other one is the client, the task of the server is to provide the content correctly, and the client also has the task of receiving the content from the server, and finally, the results will be shown to the users, and it is necessary to mention that in most cases, the client is a web.
There are various threats that can affect all systems as well as organizations, one of which is malware, there may be a security vulnerability in the browser or plug-in, and eventually the malware will get help from them in order to infect all parts of the system, this process can be done on a computer, Android operating system , iPhone and so on, die to the fact that there is no difference between them for malware because its purpose is to infect systems.As a result, it is necessary for you to be able to protect your device against the entry of this malware and prevent your entire system from being infected easily, using a VPN can increase the security of various systems against malware to some extent, but we will discuss this issue in more detail later, there are many anti-malware on the market that different users can use in order to make their system highly resistant to the entry of this malware, these anti-malware may be paid or free, obviously paid versions can provide more features for different users compared to free ones, and they are definitely of great value and have some special features that the user is willing to pay for it.In the following, we will introduce some of the best anti-malware available to you, so that you can use them in order to provide a lot of security against this malware for your system , but first it is necessary to give a brief explanation about malware and anti-malware.
What is malware?
In general, malware is considered as any malicious code that is placed on different systems which performs malicious operations, and in the end, they can cause a lot of damage to different systems and the information contained in them, these codes are actually written by programmers and can infect different user systems, they affect systems and harm the user in different ways, for example, they may send spam emails to other users after infecting the user's system, they may also steal various information, or they may gain access to different users’ accounts, and so on, all of which can cause very destructive results for the user.In fact, hackers may have different goals, so they will implement malicious acts according to their goal, for example, when your system is infected with malware, the purpose of the hacker in infecting your system may be using your system as a source to infect other systems , thus they will perform the destruction operation through your system, or the hackers may only intend to infect your system in order to gain access to important information in your system, to use the information which they have obtained in order to harm you as well as your system, there are different types of malware , which we will briefly mention below.
Types of malware:
- Virus:
Viruses in computers are very similar to biological viruses and spread rapidly all over the system, thus they spread the infection through the whole system.
- Trojan Horse:
This program is also a type of malware that at first, the users think that they can be useful for them, so they download and execute it in their system, but they don’t know that, in addition to performing the actions that the user intends, It can also perform malicious acts that are hidden from the user, in order to prevent this type of malware from entering your system , in addition to using anti-malware, you should also pay attention to the fact that you should never download the programs you want from unreliable sources, as this may cause damage to your whole system.
Adware is actually a type of malware that can have malicious effects on the target system and run without the user request, through this type of malware, hackers can corrupt the personal information of users who have been attacked.
Security is a topic that is so widespread and if users want to achieve a high level of security , it is necessary to raise their awareness as much as possible and consider its necessary points, so that they can protect their information with more knowledge, one of the important points about increasing security is the effect of using powerful antivirus software programs.McAfee and Norton are two antivirus programs that can withstand a lot of hacking threats, in addition, they have also pros and cons that need to be carefully considered as good as possible in order for you to be able to choose the best one according to your goal, both of these antivirus software programs are well known, but Norton seems to be a better antivirus than McAfee, each of which is going to be explained in more detail below.
McAfee Antivirus:
McAfee was founded in 1987 in Santa Clara, California, where it is still based, and employs more than 7,000 people, on the plus side, this antivirus has a high probability of recognizing possible threats that may infect your system, also, this program can be used with on-demand scanning, which makes it possible to use a schedule in order to check and control the specific points which you have selected, another positive feature of this antivirus is McAfee's Shredder, which in fact allows the user to delete a file forever, so that it is not available to profiteers, it should be noted that this antivirus has some features that make users prefer to use Norton Antivirus , which we are going to mention in the following.
Disadvantages of McAfee Antivirus:
- Lots of advertisements in free versions:
This antivirus software program allows users to use it for free for two months, and then they should make a purchase, it also wants a two-year commitment while purchasing which is a bit confusing, another downside of this antivirus is that when users are using it for free, they have to face with a large amount of advertisements that cannot be stopped from being displayed, which is why users do not like this antivirus despite its advantages.
- Having useless facilities:
As we mentioned before, this antivirus provides users with many features, one of which is McAfee Web Boost, which is a tool provided to various users with the aim of speeding up the browser, through which users can prevent videos from being played automatically, but this tool does not seem to be useful due to the fact that it can only be used if you are using Google Chrome browser for doing researches, other than that, you cannot get help from this features of the tool, as a result, it does not have much effect on the speed of the browser.
- McAfee’s QuickClean:
Hackers are always trying to get information about users' systems, this tool does the exact thing and provides some information for them, through which they can steal all users' information, McAfee's QuickClean provides a list of cookies and unwanted files, but it does not delete it automatically, and gives you the opportunity to examine the list and delete it by yourself which means that in the meantime, Hackers can access this list faster than you and ultimately use it in order to achieve their desires.
- The need for filling out long forms as well as weak consumer support:
Imagine that you have a problem while using this antivirus program , as a result, you try to get help from the consumer support section of the site in order to solve your problem, the important point which we have to mention is the hardness of this process because first, you need to fill out long forms which asks you a lot of personal information, then you should wait for the answer for a long time, but it may still not possible because the process has to be done over the cellphones which can make the process much harder, so this is one of the reasons for the low interest of users in using this antivirus.
