COMPARATIVE ANALYSIS OF WEB-BROWSERS

Nowadays there are many browsers, but also between the Internet users there is a question, "Which browser is best?". There are several aspects of this issue. For example, "What does a more reliable while maintaining information about the session?" or "Which browser is faster? ", etc.. Thus, under this scheme will be built and our work, which was titled “Comparative analysis WEB - browsers." To do this, we need to talk about some of the browsers that are currently most used by users.

There are the following types of browser software:

- Browser command line mode. This is the earliest browser. It doesn’t allow to view graphics, text, but support moving using IP- addresses. This type includes the earliest browsers. They do not provide the ability to view text and graphics. These browsers support the movement only with the introduction of digital addresses (IP).

- Full-screen browser. Text does not support multimedia, but it you can view the text and links.

 - Browser with support for multimedia. It is the most common browsers in the world. We use them in everyday life. It allows you to use all of the content and use of the modern Internet, such as images, sound, video and games.

 - Additional to the browser. These are the same extension settings are functional browsers. They are almost always set, as with them, you can track the work of some sites , use the API, to work with FTP, SSH, Telnet and the like.

We can also select offline browsers. These include programs, which download information from the Internet and stored in computer memory. Such information can be used without an Internet connection.

Internet Explorer. First browser faced by users of Windows. The most important advantage - it is in the operating system . Unfortunately, it is the same and the only thing: the browser is the same high performance and well-protected . Early versions (below 9) generally use dangerous because of security holes that are not saving any firewall or anti-virus software. Despite the fact that the possibilities of Internet Explorer can be extended by plugins , the main problems it does not eliminate (eg not supported WebGL). Mediocre performance , the complexity , infrequent updates - these are the main observations. However, with Flash- animations and HTML5 Microsoft product handles a little better than other browsers, but in fact that it is an interface to a common standard for Windows, facilitates the work of novice Web surfers.

Opera - the main competitor of Internet Explorer. Opera was written from scratch in C + + and uses code based on NCSA Mosaic. Sufficiently rapidly and actively spreading, many users are using it. Opera is much faster than other browsers load pages from the Internet by specific methods for processing traffic. It immediately loaded test and basic design elements and then the media data, and layout. 

You can also consider them an additional feature Opera Turbo, which helps to work with slow Internet and a relatively small amount of traffic admissible. Supplement caches the page and then it loads the server and not from the local store. However, work is not always stable. And for pages was written in AJAX, definitely not suitable. 

Size distribution Opera several times less than the same set of other browsers. Size Opera - about 3-4 Mb (not Java-based applications), while a built-in email client. 

Mozilla Firefox. A distinctive feature of this browser, which can be attributed safely to its advantages - the ability to continually expand and debugging functionality for almost any need by the incredible number of extensions. A normal user can be difficult to navigate in the ocean of additional modules and plug-ins, respectively the probability of finding the desired critically reduced. And using this browser without add-ons are not always convenient. In addition, not all extensions are written correctly - it leads to malfunction of the browser. All of the above makes the Mozilla browser - the designer who prefers only a certain category of users. Incidentally this is probably the only browser that can be obtained from the support of virtually all sites and technologies available only through extensions.

Google Chrome Pros and indeed essential : quick launch browser ( almost no noticeable difference with clean FireFox), and processing speed of opening web pages steepest among its competitors (page loaded much faster ), support for web technologies and standards for height , security holes browser with frequent updates constantly patch and finalized security system in-general . Simple and clear your browser options, your task manager , each tab in a separate process (solves the problem with hanging the entire browser) , as well as browser can work well on low-end PCs . 

And now the cons Chrome: does consume decent RAM (less than Opera , but more than Firefox ) , with a large number of tabs significantly (visually understandable) slows down the browser and a pretty big load on the processor , also portrayed rumors that Chrome sends many data on your main server and this consumes a serious ( for GPRS / EDGE connections ) the amount of traffic .

Conclusion. For today there isn’t a statement like "best browser". We can say that for each task we want to use one or the other browser.

Consider the fact that for high-speed access to the site without the use of various supplements may Opera. For easy operation Web-programmers use Google Chrome. Also it can be used to open Stock video pages and surfing. For a variety of entertainment is offered to use Mozilla Firefox or Google Chrome, and install a lot of extras. Browsers production mail.ru and Yandex, as they are distributed as viruses, by a parallel installation of various programs, like AIMP, Yandex Drive, SaveFrom.  

As can be seen from the material discussed above, many manufacturers do have something to offer, and what the user chooses, it's up to him.
