What is WWW? This question torments many people who have recently gained access to the Internet. But if you think about it, then not every experienced computer user will be able to accurately and fully answer this. So what kind of three mystical letters are we typing in the address bar of the browser to gain access to any site?
What is the world wide web?
The World Wide Web or, as it is called in our country, the World Wide Web, is a detailed version of the abbreviation WWW. It is a single network of information resources, the connection between which is provided by telecommunications and is based on the hypertext representation of data.
It would seem that now an enlightened person should understand what WWW is, but for ordinary people the above sounds at least strange.
Internet as a distributed information system
The first question to understand in order to understand what WWW is is how the network of information resources opens up for us when we use the Internet. All the information that the World Wide Web can provide us is stored on a large number of special servers, which are computers connected to one network. A user who wants to receive this information accesses the server through a special program - a browser that allows you to view WWW documents. The interaction between the server and the browser occurs according to certain rules that are embedded in the HTTP protocol.
What is hypertext?
The second question that should be considered in order to fully understand the meaning of WWW is what is hypertext. The HTTP protocol allows you to work on the Internet only with that text information that is written in a special language - HTML. It, in turn, is a markup language. It is with the help of this document format that the data can be transmitted on the World Wide Web, because it not only transfers all the necessary information, but also displays it on the user's screen in the form in which the author wanted to transmit it.
In simple terms, what is the WWW - we can say that this is the Internet. This will not be a mistake, because this abbreviation translates as the World Wide Web. It appeared in 1989, when the scientist Tim Berners proposed to the world his innovative project. 15 years have passed since then, and now in almost every house every day someone enters three WWW magic letters into the address bar of a browser to get to their favorite resource.
