A web page viewer is a program. Browsers are programs for navigating and viewing Web pages. Introduction to global networks. Basic concepts and definitions

Second, what you need to have an idea about to start working on the Internet is browser(from English browse – view), i.e. a program designed to view web documents (sometimes these programs are called “navigators” or “viewers” ​​or “browsers”).

Currently, the most widely used browser is Internet Explorer, or IE for short, which is part of the Windows operating system. It is estimated that more than 85 percent of users use it to navigate the World Wide Web. Less common browsers are Netscape Navigator, Opera, Mozilla, and others.

All browsers have their advantages and disadvantages, which consist of speed, ability to open certain applications, compliance with security requirements when working on the Internet, etc.

All modern browsers are characterized by a simple interface combined with great opportunities that they provide to users. The programs are equipped with many service functions, such as the ability to bookmarks to important pages, automatically track your route across the Internet with the ability to return. With their help, the user can simultaneously work with several different sources at once, send the pages he likes by email, and save the files he likes on his computer.

So, a browser running in a Windows environment has a standard window interface (with a window title, controls, toolbars and menus, a status bar, and a window in which the document is displayed - see Fig. 1)

The main difference between a browser window and the window of another program, for example, MS Word, is that it has additional line for entering the ADDRESS of the requested server.

In order to load the main page of a web server, you need to launch Internet Explorer, then type the corresponding address in the address window and press ENTER, after which you can watch the page gradually load (at the bottom, in the status bar, information about the progress of this process is displayed ). In Fig. As an example, Figure 1 shows the main page of the Rossiyskaya Gazeta web server.

Note that now it is usually not necessary to type the http:// prefix before the address, indicating the exchange protocol - modern browsers can independently determine the type of resource and use the desired protocol.

Third an element that you need to be familiar with to start working on the Internet is HYPERLINK.

Hypertext inventor Vannevar Bush, a science adviser to President Roosevelt, proposed the idea back in 1945. In 1965, Ted Nelson coined the term "hypertext", defining it as "non-linear text", and implemented the main ideas - namely, the ability to view document pages in any order, and not just in the "previous-next" mode. As mentioned above, the use of hypertext on the Internet led to a revolution - instead of entering complex server addresses, it became enough to simply “click” on a hyperlink, and the desired document will be opened in the same (or new) program window.

Any web page contains many hyperlinks. You can distinguish a hyperlink by changing the appearance of the cursor - as soon as the mouse cursor is over the hyperlink, it takes on the appearance of a hand with an outstretched index finger, as if inviting you to move in the indicated direction.

Thus we met addressing virtual space of the Internet, with programs for web browsing, and finally with the concept hyperlinks. This information is enough to get started.

Basic Internet services

Services refer to individual capabilities or ways of using global networks. In practical work, most of them are harmoniously intertwined into a single whole, flowing from one to another. At the same time, a novice user sometimes does not even always notice such a transition. However, at the stage of initial familiarization with the Internet, these services should be considered separately.

E -mail- Email. The first and most used Internet service. Allows you to exchange text messages, which are easily attached to any type of file, including graphics, tables, sound and video files. It is the main means of personal communication on the Internet. The World Wide Web offers a large number of free email services, the use of which does not require special programs on the user’s computer.

Usenet- a generalized name for an Internet service that provides communication for an online community united by common interests. There are several names for this form of communication: conferences, teleconferences, discussion groups, news groups, news groups of special interests. The service is built on the principle of a bulletin board with the ability to respond to published messages. Each visitor, logging onto the server, sees a list of previously sent messages indicating the sender and the topic of the statement. Any visitor has the right to send his own message or reply to an existing one. This often sparks lively discussions, sometimes involving hundreds of people from different parts of the world.

Usenet was widely popular in the first half of the 1990s. Nowadays this service has lost its former recognition, being replaced forums on websites that, while performing the same functions, do not require dedicated servers and are much easier to use and manage.

Listserv or Mailing lists- mailing lists - an Internet service that also performs the function of communication on a specific issue. Technically, Listserv is designed differently: to gain access to a specific list, you must first subscribe to it. After this, all correspondence sent to the address of this list will automatically arrive in the email inbox of each subscriber.

ICQ(the so-called “ICQ”) is a service that serves for personal interactive communication in real time. Each participant has his own identification number, which is communicated to everyone with whom he wants to communicate. The dialogue is usually conducted between two or more users and its content is not accessible to unauthorized persons.

File Transfer Protocol (FTP)- File Transfer Protocol – a service used to transfer large files. Using FTP, you can either “download” a file from a remote computer or send your own file to a remote machine. In this case, the type of file being sent does not matter.

World Wide Web- currently a basic Internet service that provides access to a huge amount of information in all possible forms: text, graphics, animation, sound, video. The World Wide Web is based on hypertext technology. Invented in the early 1990s, the hypertext markup language - HTML (HyperText Markup Language) allows you to easily include a variety of types of objects in HTML documents, which basically make up the WWW, and make links to other files, regardless of where they are are located. The unit of hypertext is a web page - the minimum document that can be downloaded and read in one go. A collection of web pages makes up a website. Data transmission on the World Wide Web is carried out using the hypertext transmission protocol - HTTP (HyperText Transmission Protocol).

Features of displaying national (non-English) characters

For historical reasons, there is only one standard for encoding English characters. But the display of characters from national alphabets (including Russian) is encoded in several different ways. A well-written web page always contains a special directive that tells the browser what language encoding method was used to compose the page. Having detected this directive, the browser activates the appropriate font so that the page is displayed correctly.

Unfortunately, many page authors ignore this simple rule and do not indicate the encoding method for the Russian language. In this case, the browser cannot independently determine which font to use to display the page and substitutes the one that is used by default. If the default font does not match the encoding used when creating the page, the user sees textual “abracadabra” on the screen and cannot read anything.

In this case, the user can manually specify the encoding method. You have to do this (at least at first) at random, sequentially going through all possible Russian encodings. Fortunately, there are not many of them, and this operation does not take much time. Currently, two Russian encodings are mainly used: WIN1251 And KOI8-R. Using the IE menu command [View -> Encoding], you can switch the current encoding, achieving a “readable” view of the page.

1.3 Exercises for independent work on the topic “Practical techniques for working with the Internet”

UPR. 1. Introducing the first methods of navigation. Launch Internet Explorer browser. Enter WWW.RG.RU into the address bar (navigation by address). Once on the page, go to other pages (sites) using hyperlinks (link navigation).

UPR. 2. Using the “Forward”, “Back”, “Home”, “History” buttons to navigate through the pages.

Explanation: The processes of moving between documents and “downloading” can be controlled using the buttons on the toolbar: “ Forward", « Back", « Stop", « Update", « Home", « Story".

UPR. 3. Save the current web page to a floppy disk or disk. Please note that the graphics used on the page are stored as separate files in a separate folder. Adding a page to the Favorites folder.

Explanation: A document "downloaded to your computer" can be saved (on a floppy disk, or in a folder on your hard drive), after which it becomes available for later viewing. At the same time, at the time of viewing, the computer may no longer be connected to the Internet (in the case of a session connection). When you save a document, all the pictures it contains are automatically saved.

In addition to saving the document (page), it is possible to save a link to the page you like (its URL) in a folder Favorites, so that it would be easy to return to it later (i.e., make bookmark). When saving, you can make this page available for offline work, i.e. without network connection.

UPR. 4. Load the web page you are interested in. Try printing this page using the menu option File - Preview - Print.

EXECUTIVE 5. Search for the desired piece of text on the page (using the CTRL+F combination, a window for entering a keyword for search is called up).

EXERCISE 6. Change the font size on the page for more comfortable viewing (find the corresponding option in the “View” menu).

Explanation: you can use the found text as the basis for a new document, for which it is most convenient to use the ability to copy a selected (using the mouse) fragment of text to the clipboard, and then paste it from the clipboard into a Word document.

EXERCISE 8. Opening a new document (using a hyperlink) in a new window.

Explanation: It is often convenient to keep multiple web pages open at the same time. To do this, the following technique is usually used - if you press and hold the “SHIFT” key while “clicking” on a hyperlink, the web page corresponding to this hyperlink will be opened in a new window.

EXECUTIVE 9. Compiling a list of required addresses (URLs) in a Word document.

Explanation: Sometimes you need to print or mail a list of useful website addresses or web pages to a colleague. To do this, you can use the following technique - copying the hyperlink (or address) to a clipboard, then pasting it into a Word document with the necessary explanations. Explore this feature by selecting the desired link, pointing at it with the mouse cursor and right-clicking to bring up the context menu (with the options “Copy” and “Copy link”)

Programs for viewing web pages

Browsers are programs for viewing Web pages.

Lecture No. 6

One of the basic tasks of the Internet is to store and provide (on request) extremely important information to users. To find the necessary information on the Internet, it is extremely important to know the address of the Web page (site) on which this information is located, to have at least one of the Web browsing applications installed on your PC, and to have access to the global network.

A program for navigation (searching for information on the Internet) and viewing Web pages is usually called browser(browser). The word browser is derived from the English " Web browser"There are many browsers today.

The most popular are graphical browsers(two-dimensional):

Internet Explorer

Mozilla Firefox

· Flock (Firefox and Flock are based on Netscape code)

Netscape Navigator

· Google Chrome and others.

Internet Explorer browser page

The Safari browser for Windows is gaining popularity. The first graphical browser, Viola, appeared in 1992. Currently, three-dimensional browsers are being developed, for example the Clara browser

Popular text browsers(console browsers):

· Links (supports graphics).

Lynx and Links can be used on various platforms: Unix, Macintosh, Windows and other operating systems. These browsers are suitable for use on weak PCs and low-speed Internet connections.

At the same time, these browsers can be used for powerful PCs and high-speed lines for navigation or Internet surfing (for quick access to the required information on sites), and to view the required Web pages, it is advisable to use browsers with a graphical interface.

To work in DOS, you can use a graphical WWW browser Arachne is a graphical browser that supports the basic elements of modern Web design. To work in Linux, you can use the following browsers: Lynx, Links (Elinks, Links2, Links Hacked), Opera, Netscape, and so on.

Browsers are the client World Wide Web, that is, an application program that, upon request, receives documents from Web servers, interprets the data from Web pages and displays them on the screen.

Using a browser, you can easily search for the desired web page on the Internet by typing one or more words in the address bar (search bar) of the browser and pressing Enter to begin the search. Browsers provide access not only to Web servers, but also to other Internet servers (FTP servers, Gopher servers and UseNet teleconferencing servers).

One of the most popular browsers is Internet Explorer, since the Internet Explorer application is included in the Windows operating system.

    INTRODUCTION

    A web page is a document whose content is suitable for processing, manipulation and viewing via a web browser. Web pages can be located locally (on the user’s personal hardware device) or on network devices (servers) in local and global networks.

    A typical web page is an HTML text file that may contain links to files in other formats (text, graphics, video, audio, multimedia, applets, applications, databases, web services, etc.), as well as hyperlinks to quickly navigate to other web pages or access referenced files. Many modern browsers allow you to view the contents of referenced files directly on the web page containing the link to the file. Modern browsers also allow direct viewing of the contents of certain file formats, away from the web page that links to them.

    Website is a collection of several web pages united by a common design, a common theme or a common goal. That is, “Simply and Clearly” is a site that combines many pages with articles. The design is made in the same style, that is, everything is decorated similarly. Therefore, not only the commonality of the topic (learning to use a computer), but also the appearance itself indicates that the pages are related. But at the same time, the separately open main prosto-ponyatno.ru is a web page.

    There are also one-page sites, but most of them include several pages: main and internal, on which various information is located.

    Each site has Domain name, that is, your name on the Internet.

    A dynamic page is a web page generated programmatically, as opposed to a static page, which is simply a file on the server. The server generates the HTML code of the dynamic page for processing by the browser or other user agent.

    Dynamic pages typically process and display information from a database. The most popular technologies for generating dynamic pages at the moment:

    · PHP - For Apache and other servers running GNU/Linux, other UNIX-like, and other operating systems.

    · JSP and Java Servlet - For Apache, JBoss, Tomcat servers running various OS.

    · ASP.NET - For Microsoft Windows servers running IIS.


    WEB PAGE CREATION TOOLS

    HTML language

    Web pages can exist in any format, but the standard is Hyper Text Markup Language, a hypertext markup language designed to create rich text rich in images, sound, animation, video clips and hypertext links to other documents scattered throughout the Web. space, and located on the same server or being an integral part of the same Web project.

    You can work on the Web without knowing the HTML language, since HTML texts can be created by various special editors and converters. But writing directly in HTML is not difficult. It may even be easier than learning an HTML editor or converter, which are often limited in their capabilities, buggy, or produce poor HTML that doesn't work across platforms. The HTML language comes in several flavors and continues to evolve, but HTML constructs will likely continue to be used in the future. By learning about HTML and understanding it more deeply, creating a document at the beginning of learning HTML and expanding it as much as possible, we are able to create Web pages that can be viewed by many Web browsers, both now and in the future.

    This does not exclude the possibility of using other methods, such as the advanced method provided by Netscape Navigator, Internet Explorer, or some other programs. Working with HTML is a way to learn the ins and outs of creating documents in a standardized language, using extensions only when really necessary. HTML has been ratified by the World Wide Web Consortium. It is supported by several widely used browsers, and will probably form the basis of almost all software that has to do with the Web.

    Web browsing programs

    Simple pages will most likely look the same in all browsers. However, the more complex the page, the greater the differences in its perception by different viewing programs. When creating a web page, it's useful to view it in different browsers and adjust the code according to what you see. It can often happen that a page that looks very nice in one browser will simply be unreadable in another.

    Creating a complex page that looks almost the same in different browsers is not an easy task: Therefore, we would recommend focusing on one browser, and maintaining compatibility with others only at a minimum level. You can also create copies of pages for different browsers, but there is also a small problem here, which we will discuss below.

    The simplest solution: having created a page, write at the beginning of it something like: “Looks best in such and such a browser” and place a link next to it by clicking on which the user could download the desired viewer program. However, we must keep in mind that not all users will most likely want to do this, and not only because not all browsers are free. Firstly, not everyone has the opportunity) to download large amounts of data from the Internet, and secondly, many are already accustomed to using some kind of viewing program, and advice to urgently install another one will cause them, at best, bewilderment.

    Internet Explorer browser

    Today, the most popular web browsing program is Microsoft Internet Explorer, which is used by approximately half of all Internet users.

    Almost all the cardinal innovations have appeared in MS Internet Explorer since version 4. Some aspects, mainly related to the reaction to user actions and the interpretation of code written in JavaScript, have changed significantly in the fifth version. Therefore, do not be surprised if a page written for Internet Explorer version 5, when viewed in version 4, displays, for example, messages about a “script error.” By the way, the fifth version of Internet Explorer is capable of automatically correcting minor inaccuracies. Other browsers do not do this, and for them these inaccuracies will result in error messages.

    Internet Explorer supports JavaScript as a scripting language. The VBScript language introduced some interesting features that were missing in JavaScript 1.0, such as the function of automatically ignoring errors in a loop

    The third version uses a rather unique implementation of JavaScript, and some functions written for later versions or for Netscape browsers do not work quite correctly in Internet Explorer 3. The HTML 4.0 project was still in its infancy; Internet Explorer 3 lacks functions for responding to user actions, the ability to arbitrarily arrange design elements, etc. There is also no support for cascading style sheets. In some cases, there are problems with navigation between frames.

    1.4. Website builders

    A solid foreign project, quite possibly the best website builder today.

    2. CREATE A WEB PAGE
    USING HTML LANGUAGE

    As mentioned above, web pages are encoded in hypertext markup language - HTML. Generally speaking, to write an HTML file, it is enough to have any text editor, as long as it knows how not to add its own special characters to the text. The simplest option is the Notepad editor, which comes standard with Windows. Strictly speaking, this is exactly what you need - a simple program that saves the written text exactly in the form in which it was entered, and nothing extra.

    A web page is an electronic document in .htm or .html format that has hyperlinks to other documents. A web page is an electronic document created using a special hypertext markup language, HTML, possibly using scripts written in the JavaScript programming language or using the Perl, PHP programming languages.

    A tag is a set of characters that begins with the symbol< и заканчивается символом >(angle brackets between which the keyword is written):<………>

    HTML Document Structure

    The web page consists of three parts:

    1. HTML version information,

    2. The header of the web page, which contains technical information ( ),

    3. Body of the web page ( ).

    All HTML documents have a strictly defined structure, which is created using tags such as

    …- This pair of tags tells the browser that this is indeed an HTML document.

    …- The headers section, which contains information about the document as a whole, in particular it should contain the following tag:

    - A tag containing the title of the document, which will be displayed in the title bar of the browser window.

    …- The body of the document, i.e. The text itself, the contents of the document, will be located here.

    Internet Browser Review

    Browser(or browser) is something that no Internet user can do without. The word browser is derived from the English " Web browser".

    This word refers to software for processing and displaying various components of a web page and providing an interface between the website and its visitor.

    Almost all popular browsers are distributed free of charge or “bundled” with another application.

    The history of browsers dates back to 1990. It was then that the first mass web browser was created.

    The creator of the first browser was the developer of hypertext markup, the “father” of World Wide Web technology, Tim Berners-Lee. The browser was called WorldWideWeb.

    Later, in order not to confuse the “World Wide Web” with the name of the program, Berners-Lee renamed the browser Nexus.

    WorldWideWeb allowed you to view web pages, as well as edit and update them on sites.

    It was a text browser capable of displaying only letters and numbers. The first popular browser

    with a graphical interface was NCSA Mosaic.

    The source code of this browser was open source and several other browsers (Netscape Navigator and Internet Explorer) took it as a basis. This browser had its shortcomings, but almost all of them were eliminated in the Netscape Navigator browser (some Netscape employees were from the NSCA and participated in the development of Mosaic)..

    Netscape released Netscape Navigator for various operating systems (UNIX, Windows, Mac OS) and achieved notable success, including commercial success. This prompted Microsoft to release its

    Internet Explorer browser

    If we take the Russian-language part of the World Wide Web, the so-called Runet, then the browsers are located in a slightly different sequence: Internet Explorer - 51%, Firefox - 24%, Opera - 16%, Opera Mini - 4%, Safari and Chrome - 2%. The main difference with global trends is the greater popularity of the Opera web browser. Perhaps this is due to the fact that Opera presented itself to domestic users as the first real alternative to Internet Explorer..

    In any case, regardless of the language segment of the network, Internet Explorer is still

    the most popular web browsing program

    From the point of view of vulnerability, the most common browsers were considered - Firefox, Safari, Opera and Internet Explorer. The Google Chrome browser, by the way, is not mentioned in this report.

    According to Cenzic, 8% of all security problems on the world wide web are related to browsers. Based on the results of the first half of 2009, Mozilla Firefox turned out to be the most vulnerable - 44% of all threats found were detected in it.

    Internet Explorer 1.0 was released in August 1995, based on the Spyglass, Inc Mosaic browser.

    Microsoft licensed the browser for quarterly payments plus a percentage of sales. Internet Explorer developed gradually: from the first version 1.0 to the latest version 8.0, almost 13 years passed. During this time browser

    has become increasingly integrated with operating systems and support for various website builders.

    The appearance changed dynamically, features were gradually added: multimedia panel, integration with Windows Messenger, automatic image size correction, download manager, page tab system, search bar, blocking pop-up windows and banners, and so on. Some of the new features in the latest version of Internet Explorer 8:

    Mozilla Firefox 3.6

    Introducing Internet Explorer

    Go to web page

    To go to web pages you can use:

    · Panel Address, where you enter the address of the Web page you are interested in

    Using hyperlinks

    Almost every Web page contains links to other pages. The easiest way to move from one Web page to another is to find the hyperlink of interest on the page and click on it (text hyperlinks are underlined, the text of links to pages that have already been visited changes color). There are also graphical hyperlinks that are not clearly highlighted on the screen and one image can contain several links. For example, individual parts of a person's image may be used to link to sections of hats, clothing, and shoes. When you move the mouse cursor to a graphical link, the arrow takes the form of a palm with a pointing finger (in addition, the status bar displays the addresses of the Web page to which the selected hyperlink points).

    When using graphic links, Web page designers strive to make them stand out. To do this, the image with the link may contain explanatory text. Quite often, an explanation of this link is provided next to the image.

    When you click on a link, the Web page specified in it opens by default in the current browser window. It can also be opened in a new window. To do this, place the cursor on the link, right-click and select the command from the context menu that appears Open in new window.

    Using the Web Page Address

    The most universal way to navigate to a Web page is to use its address. The Web site address (URL - Universal Resource Locator) usually begins with the name of the protocol. This is followed by the domain name and the location of the file relative to the domain. If you specify only the domain name, the main page of the Web site will load. For example, the Encyclopedia of Cyril and Methodius has the following address: http://www. *****. Here http- the protocol that your Web program uses to communicate with a Web site and retrieve a Web page from it. The next part of the address, www, indicates that the site is a World Wide Web site. Suffix ru means that the node is located in Russia, and the address section indicated before it km clarifies whose node this is.

    Default panel Address located under the main browser toolbar. When you enter an address in the drop-down list in this panel and press the key or button Transition The browser opens the Web page whose address you specified. All the addresses that you previously entered into the panel Address, are in the drop down list and you can select them.

    https://pandia.ru/text/78/184/images/image019_16.jpg" width="468" height="87 src=">

    You don't have to enter the initial part of the address http://www, because the browser will add it itself. If you don't enter com, org, etc., the browser will begin searching for Web sites with all valid suffixes.

    Go to Web pages open in the current session

    To go to pages loaded in the current session, use the buttons Back and Forward. By clicking these buttons, you sequentially go to previously loaded pages. To go directly to the page, click the arrow next to the button Back or Forward. A list of pages will open. By selecting the required page from the list, you will immediately go to it.

    Navigating a Web Page

    If the Web page fits on the screen, then you don't need to navigate around it. But in most cases, a Web page is large enough that you can use your mouse and keyboard shortcuts to navigate it.

    As with any Windows window, you can use scroll bars to move around a Web page. It's common for Web page designers to place bookmarks on large navigation pages. Typically, in this case, at the beginning of the Web page there is its table of contents, each section of which has its own bookmark. When you click on a table of contents line, you go to the specified section located on that page.

    Internet Explorer stores all the Web pages you visit in temporary files on your hard drive. Internet Explorer typically loads each Web page once per session. For example, when you open a page for the first time in a session www. , Explorer saves it, including all page objects, in temporary files. If you then open other pages and then return to the previously selected page, Internet Explorer will load it from your hard drive rather than from the Internet.

    You can configure the mode for using temporary files. To do this, open the dialog box Internet Options and in the region Temporary Internet files tabs Are common click the button Options (Settings).

    Formation of search criteria

    In the examples above, only one keyword was used for the search. When specifying such a search criterion, it is very difficult to find the required data, since there may be too many Web pages containing it. Sequentially browsing not only Web pages, but even a list of them will take too much time. Therefore, to set a more precise criterion, it is advisable to use the capabilities of search services. Search guidelines may vary between services, but you can always find help information on the main page for each service. As an example, let's look at organizing a search using the Yandex search engine.

The search engine will select a list of Web pages that contain all of these words. At the beginning of the list will be the documents in which the query words occur the greatest number of times and are as close to each other as possible.
