Introduction

Receiving Web pages from the Internet and their display is a fairly difficult task. For this purpose, we use special programs for viewing Web pages. Such programs are called browsers. Browsers appeared almost simultaneously with the World Wide Web concept and have passed a big way of development.

Browsers (Internet viewers) and are discussed in this work.

1. MICRSOFT Internet Explorer program

Currently, Netscape Navigator and Microsoft Internet Explorer browsers are most popular, although there are other programs designed for this purpose. The Internet Explorer browser appeared later than Netscape Navigator, but gradually conquers increasing popularity, although this does not indicate that this product is better. It is not only here as, but also that Microsoft has included Internet Explorer 4.0 to the Windows 98 operating system as a standard WEB viewer. Starting with this version, the program is no longer a browser, but a Web Observer. The main purpose of the browser is to download Web pages from the Internet and displaying it on the screen. Web page location is determined by the URL address. This is a special form of recording the address of the document used on the Internet, it allows you to unambiguously specify the desired document, on which network server it is. The priority of the program is to view the Web pages that are displayed in the workspace: its windows. However, the Internet is not reduced only to Web pages. Full-scale network work requires the use and other possibilities of the browser. It allows you to download arbitrary files from the Internet: programs, archives, reference information without resorting to the help of additional software. The FTP service is engaged in transmitting files over the Internet, and the browser is able to work with this service on its protocol. Some Internet services (for example, mail, teleconference) are not available directly from the Internet Explorer program, but in such cases the program provides funds for rapid access to them using auxiliary programs. Real work on the Internet can be started only after establishing an Internet connection. In this case, after starting the Internet Explorer program, the main page is loaded and displayed to which the browser is configured. One document is displayed in the browser window. Typically, the Internet web pages are viewed in series, in order to find those that contain the necessary information. As a rule, Web Pages are complex combined documents containing both text information and built-in objects. Currently, most Web pages are richly illustrated. As illustrations, both images and sounds, videos and other objects belonging to multimedia are used. A variety of embedded objects is constantly increasing. Web pages are formatted electronic documents, in many respects reminiscent of documents created by the text processor. However, they have important features. In the text processor, documents are preparing, about which is known in advance, in what form they will be played (for example, printed on a sheet of paper of a certain size). Web documents are more versatile: they must be read easily regardless of what size and resolution has a reader's screen, and on how many colors it reproduces its equipment. The most high-quality Web pages are so universal that you can even work with them with the simplest non-grief browser. The modern variety of Web pages and the constant appearance of new types of objects included in their composition leads to the fact that the tools of viewing Web pages can not always play the objects encountered in the Web documents. First browsers were able to play only text (with hyperlinks). Modern viewers can work with many types of objects, but still not with everyone. The problem of playback on web pages of various types of objects is solved either by connecting additional applications, or by expanding the possibilities of the browser. Accordingly, programs intended to display embedded objects are used as auxiliary or as built-in applications. Auxiliary application is the usual application from the number installed on a computer that can be used to display the Web page element. If necessary, such an application is automatically started by the browser. This opens a separate window. The integrity of the Web page is somewhat violated, but the entire information available on it is displayed. The built-in application is a special kind of application that works only under the control of the browser. Built-in applications are used to display objects within the Web pages without opening a separate window. These applications start automatically when the browser faces the corresponding object. Currently there are hundreds of built-in applications. With their help, you can play any objects encountered on Web pages. The worldwide network servers store multiple files of mass interest. These are programs, archives, reference documents. These files can be stored both on conventional Web nodes containing web pages and on special nodes containing only files. And in that and in another case, hyperlinks use hyperlinks from the Internet. Such hyperlinks indicate not on the Web page, but to the file stored on the Web node or in the FTP archive. This may be a file of any type, although archives are considered to be generally accepted in format.zip or self-extracting archives (EXE). Loading and saving files is somewhat different from downloading Web pages, since in this case another data transfer protocol is used. In particular, before downloading the file, you must inform the program for more information.

2. Automatic receipt of data from the Internet

So far, we are talking about the Internet as a passive source of information. If you need to get data, the browser indicates the desired address and it makes a request to the network. In such a scheme, the Web nodes on which the Web pages are published do not take any action before receiving the request. Thus, for information, active actions are needed by the user. In such cases, it is said that the connection is carried out at the initiative of the user. Internet Explorer browser is not subject to such restrictions - it is able to receive information from the Internet without active user actions. For this, the program implements two mechanisms - subscription and channels. Thanks to the subscription, you can configure the browser so that the information from the necessary Web nodes will be automatically updated on the computer on a specified schedule. You can proceed easier and instruct a Web site to send only a notification that the data on the page of interest has been changed, but you can order and automatically transmit all updated pages.

Special form of subscriptions are channels. These are special Web nodes that automatically update information on a specified schedule. In this case, the initiator of the connection is not a user, but a Web node. Of course, if the user's computer will not be connected to the network in the clock, the communication session will not take place. If the contents of the channel must only be viewed, the subscription is not required for it. When using the channel, a non-simply web page is displayed, but a full-scale card of the entire Web site that provides quick access to the desired data. The list of most channels operating on the Internet can be found on the MICROSOFT Web site. This list is updated regularly. A list of multiple channels (including Russian) is supplied with the browser as part of the Windows operating system. Additional channels can be installed on a computer.

Automatic reception of web-pages from the Internet to convenient (for example, in a night or non-working) time means that it is possible to view them without connecting to the network. View adopted information without connecting to the network is called autonomous viewing. Such a mode of operation is useful, for example, if at working time it is undesirable to occupy a telephone line. Downloading Web Pages To view offline is carried out in advance using subscriptions or channels. Automatic data receipt is implemented not only in Internet Explorer. For example, in the application-application viewer Pixgrabber pictures, a metapoisk is implemented using the 7 most popular online search engines specialized to search for pictures. The program also allows you to collect pictures from the Internet without the need to visit sites - you just need to specify the URL from which it will start the download and the depth of the pages' nesting level from which the pictures should be downloaded. Pixgrabber collects pictures from visited Web pages in manual and automatic modes. In automatic mode, pictures are recorded in the database on the background, without user participation. Entered the archive pictures can be tied to the heading (rubrics), to accompany the rating and its own comments. The intelligent algorithm for recognition of duplicate pictures not only allows you to quickly find a duplicate pictures in the archive, but also allows you to recognize them already at the stage of enhancing pictures to the database. PIXGrabber is also a full-featured bookmark manager and allows you to add comments from the Internet Explorer browser to add comments to the page being viewed. Pixgrabber allows you to mark the previously visited links (by default in the form of crossed text), so that you can avoid re-opening the web page already viewed.

Conclusion

The Internet Explorer Writer's program is essentially an extension of a program-oriented conductor program not only with the file system of this computer, but also with web documents of the Internet. If you consider local folders and files, too, as part of the Internet, then any document available for this computer can be addressed to using one program.

This means that Web pages posted on remote servers can be viewed as regular documents.

3.2.5. Web page View Application Programs

The essence of the WORLD WIDE WEB system (WWW) is to use a hypertext model to information resources distributed in the global network. WWW is one of the types of service. WWW provides the ability to work with documents that combine text, graphic images, sounds, animation, which greatly facilitates the perception of information. Hypertext documents (Web Pages) are created using the Special HTML Hypertext Marking Language (Hyper Text Markup Language).

The WWW system works on the client-server principle. The client is an HTML interpreter, a special viewing program, called WWW-browser (WWW-Browser). The WWW browser is an application program that interacts with the WWW system receives the requested documents, interprets the data and displays the content of the documents on the screen. The Client Program provides access to almost all Internet information resources that are stored on servers.

To work with the WWW system, you must install one of the web pages view programs, such as Internet Explorer, Mozilla Firefox, Myie Web Browser, Opera, etc. Most browsers provide access to other Internet servers: to FTP servers, Gopher servers and USENET teleconferencing servers.

Internet Explorer Explorer

Internet Explorer is installed together with Windows installation and the Internet Explorer browser icon appears on the desktop. This icon can be used to run the Internet Explorer program. After starting the Internet Explorer web pages, the browser window appears on the screen.

Fig. one.

The Internet Explorer viewer or browser window contains:

menu bar;
three toolbar: regular buttons, address string, links;
status bar.

Panel The usual buttons contains all the main browser control buttons. Panels Address and links are used to specify the address of the downloadable Web page.

The status bar located at the bottom of the window contains the status messages of the Web page. The process indicator on the right side of the status string reflects the file loading process. The status bar also contains an indicator showing the installed security level of downloadable Web pages.

To go to the web pages you can use:

hyperlinks contained in the open page;
the address panel on which the address of the required Web page is entered;
links and favorites panels.

Use hyperlink

Each Web page contains links to other pages. The easiest way to go from one web page to another is the transition using a mouse manipulator. To go to other pages, you can use the navigation menu, text hyperlinks, graphic hyperlinks.

Usually text hyperlinks are emphasized, so they can be easily found. Text links to those pages that you have already visited, changes its color. It is more difficult to determine graphic hyperlinks. If when installing a cursor to the image, it takes a palm view with pointing finger, then this is a hyperlink.

The drawing can be saved as a separate file. To do this, from the context menu of the picture, run the "Save Image As" command. When saving the pattern, you can select the type of file that matches the pattern type, or save the drawing in BMP format.

Windows Internet Explorer is a series of browsers developed by Microsoft since 1995. Included in the Windows Operating Systems of the Windows family. Internet Explorer is the most widely used web browser since 1999, in 2002-2003, reaching its maximum mark of 95% according to this indicator. However, recently, its share is rapidly declining, giving way to such browsers as Mozilla Firefox, Google Chrome, Safari, Opera, and others. To date, the last stable version of the browser is Internet Explorer 9. Additional browser modifications for other operating systems were also released. , such as Internet Explorer Mobile (for Windows CE and Windows Mobile), Internet Explorer for Mac and Internet Explorer for UNIX.

Internet Explorer can be downloaded for free, and it will work even being installed on the illegal copy of Microsoft Windows, however, the license agreement allows you to install Internet Explorer only if there is a legal license for the Windows family system.

Mozilla Firefox is a freely distributed browser, which is included in the Mozilla Application Suite program, the development and distribution of which Mozilla Corporation is engaged. The browser present an interface with many tabs, checking spelling, search as dialing, "live bookmarks", download manager, field for accessing systems. New features can be added using extensions.

Firefox is officially produced for Microsoft Windows, Mac OS X and Linux. Informal builds for FreeBSD, BEOS, and many other UNIX-like operating systems are available. The browser code is open and distributed under the triple license GPL / LGPL / MPL.

Initially, the browser was called "Phoenix" ("Phoenix"). After some time, the browser was renamed "Firebird" ("Firebird") due to the conflict of trademarks, but this name later was changed to "Firefox" for a similar reason. However, "Firefox" turned out to be a trademark of The Charlton Company in the UK, which was reflected in the "On Program" dialogue for English-speaking builds.

Some browser properties:

blocking pop-up windows (eng. Pop-Up);

tabs support (eng. Tabbed Browsing) (multiple pages in one window);

built-in search engines and dictionaries panel;

so-called "live bookmarks" (eng. Live Bookmarks) - RSS-flow integration mechanism;

almost unlimited possibilities for configuring behavior and appearance, including due to the use of extensions, topics and styles;

support for multiple extensions - for Firefox they are created multiple times more than any other browser;

built-in web developer tools;

automatic update both the browser itself and its extensions (from version 1.5);

Displaying content immediately (allows you to comfortably continue the surfing even with incomplete loading of the page, which is especially noticeable with a slow connection and a large number of objects embedded);

Secure password storage for sites and certificates Thanks to the ability to set a "master password", which encrypts all other passwords (using the 3-DES symmetric encryption algorithm and protects access to user certificates. Thus, the theft (extraction) of the saved passwords is difficult even with physically accessing the attacker to the computer. When you first enter the master password displays its design quality (difficulty hacking).

Opera - web browser and software package for work on the Internet produced by Opera Software. Developed in 1994 by a group of researchers from the Norwegian company Telenor. Since 1995, the product of Opera Software, formed by the authors of the first version of the browser. The total market share of Opera and Opera Mobile in June 2011 was 2.98%. In addition, the proportion of Opera Mini was 1.25%. In Russia, the percentage of browser users is much higher than the average. By June 2011 Opera, along with MINI opera, ranks first in popularity in Russia with 37.4% of users.

The browser is written in C ++ programming language, has a high speed of work and compatible with basic web technologies. Distinctive features of Opera for a long time were a multi-page interface (the system of tabs in the program window) and the ability to scale the displaced documents entirely, along with graphics; Subsequently, these functions appeared in other browsers. Opera enhanced functionality of the use of the mouse: In addition to standard navigation methods, the so-called "mouse gestures" are provided. The browser security system includes: built-in phishing protection; Additional information flow encoding when working with pages containing confidential information requests; The ability to delete http-cookies, cleaning the history of the visits by one mouse click, as well as the starting panel "Speed \u200b\u200bDial".

In addition to the main features of the browser, in the time the package has passed since the appearance of the package, the Opera Mail mail / news client, the address book, the Customer of the BitTorrent Pirot Network, the RSS Aggregator, the IRC client, download manager, WAP browser, Opera Link, As well as widgets - graphic modules based on HTML technology and working outside the browser window.

Opera browser is ported for a variety of operating systems (including Microsoft Windows, Mac OS X, Linux, FreeBSD, Solaris, as well as for mobile platforms based on Symbian, Meego, Meego Wetab, Java, Android, Windows Mobile, Windows 7, Apple iOS.

Opera is also the only browser for Nintendo DS and Wii game systems. Some computer telecases also use Opera.

Opera for PC and Opera Mini are distributed free since 2005, Opera Mobile - from 2010.
