Undoubtedly, the emergence of the world wide web was a serious and cardinal leap that supplemented, and in some cases replaced the existing picture of the world. After all, every day a global network with billions of invisible threads involves and connects more and more new users around the world.
The official birth year of the world wide web is considered 1989, when the world hypertext project was proposed by Tim Berners-Lee. The essence of this project was the publication of 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 cannot be imagined. And hypertext documents are those very numerous sites. The world's first web site 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 instructions for installing servers.
The World Wide Web includes millions of web servers located around the world, denoted by the familiar acronym WWW (World Wide Web). A web server is a computer program designed to transfer data using the HTTP protocol. This program runs on a computer connected to the network.
The principle of the web server is as follows: after receiving an http request, the program finds the requested resource on the local hard disk and sends it to the computer of the requesting user. He can view the information received using a special program of a web browser, the main function of which is to display hypertext.
How the World Wide Web Works
Hypertext documents are nothing more than 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 placement, storage, access to these resources, the HTML language is used, without which it is simply impossible to imagine modern site 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 storage location on the server and the domain name required to find and identify a specific site on the world wide web.
Reflection of information
There are two ways to reflect information on the web: active and passive. Passive display allows the user only to read information, while active display means the ability to add and edit data. Active display includes: guest books, forums, chats, blogs, wiki projects, social networks, content management systems.
