A distinctive feature of the web document is. Test on the discipline "Information technologies"

A distinctive feature of the WORLD WIDE WEB environment is the presence of a transition tools from one document to another, thematically associated with it, without explicitly specifying the address. Communication between documents is carried out using hypertext links (or just hyperlink). The hyperlink is a dedicated fragment of the document (text or illustration), with which the address of another Web document is associated. When using a hyperlink (usually it is necessary to bring the mouse pointer to it and click on it) there is a hyperskalk - opening a web page to which the link indicates. The hyperlink mechanism allows you to organize the World Wide Web travel thematic journey without using (and even knowledge) addresses of specific pages.

Addressing documents.

To record addresses of Internet documents (Web pages), a form called URL address is used. The URL address contains instructions on an application protocol, a computer address, and a document search path on this computer. The address of the computer consists of several parts separated by points, such as www.amik.ru. Parts of the address located on the right, define the network affiliation of the computer, and the left elements indicate a specific computer of this network. Converting the URL address to the digital form of the IP address manufactures the domain name service (DNS). A slash symbol is always used as a separator on the way of searching for the Internet document.

WEB viewing tools.

Internet documents are designed to display in electronic form, and the author of the document does not know what the ability of the computer on which the document will be displayed. Therefore, the HTML language provides not so much formatting the document, how much is the description of its logical structure. Formatting and displaying a document on a specific computer is made by a special program - browser (from the Browser's English word).

Basic functions of browsers:

establishing a connection with the Web server on which the document is stored, and load all components of the combined document;

interpretation of HTML tags, formatting and displaying a Web page in accordance with the capabilities of the computer on which the browser works;

provision of means to display multimedia and other objects that are part of the Web pages, as well as an extension mechanism that allows you to configure a program to work with new types of objects;

ensuring the automation of the search for Web pages and simplify access to web pages that have previously visited;

providing access to embedded or autonomous means to work with other Internet services.

Search engines.

The Internet is growing in a very rapid pace, and find the necessary information among tens of millions of documents (web pages, files, etc.) is becoming more complicated. Special search servers are used to search for information, which contain more or less complete, but constantly updated information about Web pages, files and other documents stored on tens of millions of Internet servers.

Various search servers can use various search engines (Search Engine) search, storing and providing information to the user. However, the general is that by the time of the user request, all information about Internet documents in a compact form is stored in the database of the search server.

Existing search engines It is possible to divide into three groups ::

Directories (thematic directories) Internet.

Search systems for general purpose (index).

Specialized search engines.

Internet directoryit is an analogue of the thematic pointer in the library: it allows you to find the most significant WWW documents on a given topic. An example of such systems is the search server Yahoo:

http://www.yahoo.com.

General Purpose Systems Allowed to find documents in WWW by keywords. The principle on which most of these systems is based is that special robots programs automatically bypass WWW servers read and index all the documents that meet keywordsrelated to k. this document, and remember them along with the URL of this document in the database. Most search engines also allow the author of the new Web page to make information to the database itself.

Turning to such a search engine, we display one or more keywords, which, in our opinion, could bring us on the information you are interested in, and send a request with one click on the on-screen button, usually called the search (submit). After a few seconds, the search engine will return the list of URLs in which the keywords specified by us were found. An example of such a search engine is Rambler:

http://www.rambler.ru.

Specialized search engines Allow us to find information, on specific sciences, specializations, according to the areas you are interested in. An example of such a search engine is http://www.avatarsearch.com/. The search engine Avatarsearch is designed for people who are interested in issues of occultism and mysticism. Links to pages whose authors have particularly succeeded in illumination of this topic, receive a special sign of distinction from the creators of this site.

Fig.1 InterfaceRambler.

Since the information on the Internet is constantly changing (new documents are created, old, etc.) are deleted.) Search robots do not always have time to track all these changes. The information stored in the database of the search server may differ from the real state of the Internet, and therefore sometimes the user can get a reference to an already existing or displaced document.

The search server interface is usually approximately the same, and

Fig.2 Search results

therefore, we consider it on the example of the Russian search server Rambler ( http://www.rambler.ru.).

The search engine start page contains a list of sections specifying the search area, and the search field. In the search field, the user can enter keywords to search for a document, that is, words that, according to the user, will allow you to identify the document.

We will put the task of finding information about textbooks on computer science. However, before entering keywords in the search field, it is advisable to narrow the search area by selecting a category of education from the list of sections.

You choose the words as keywords: informatics, tutorial, directory - and introduce them in the search field. As a result, we obtain explicitly redundant information, a list of almost 90 thousand documents, since the word informatics is contained in 519249 documents, the word textbook - in 885564 documents and the word catalog - in 12622835.
