What is the World Wide Web?


The official birth year of the world wide web is 1989, when the world hypertext project was proposed by Tim Berners-Lee. The essence of this project was to publish hypertext documents linked by hyperlinks in order to facilitate the search for documents by CERN scientists, where Tim worked at that time. He developed URIs, the HTTP protocol and the HTML language — everything without which the modern Internet is already impossible to imagine. And hypertext documents are the most numerous sites. The world's first website was hosted by Tim Berners-Lee on August 6, 1991 on the first web server. He explained the very concept of the world wide web and the instructions for installing servers.


The World Wide Web includes millions of web servers located throughout the world, denoted by the familiar abbreviation WWW (World Wide Web). A web server is a computer program designed to transmit data using the HTTP protocol. This program runs on a computer connected to the network.
The principle of the web server is as follows: upon receiving an http request, the program finds the requested resource on the hard local disk and sends it to the computer of the requesting user. He can view the received information with the help of a special web browser program, the main function of which is to display hypertext.

The principle of the world wide web

Hypertext documents are nothing but web pages. And such a familiar concept today as a website is several web pages united by a common theme, hyperlinks and stored, as a rule, on one server. For the convenience of placing, storing, accessing these resources, the language of HTML is used, without which it is simply impossible to imagine modern website building. Users can navigate between sites and documents of one site using hyperlinks.
But the prescribed HTML file itself is not a site until it is posted on the Internet. For the existence of each site it needs hosting, i.e. the place where data is stored on the server and the domain name necessary to find and identify a specific site on the world wide web.

Information Reflection

There are two ways to reflect information in the web: active and passive. Passive mapping allows the user to only read the information, the active implies the ability to add and edit data. Active display includes guest books, forums, chats, blogs, wiki projects, social networks, content management systems.
