Entering any given address in a search string of the browser, almost nobody thinks of value of strange abbreviations www and http. They are considered as the same integral address attribute of the website, as well as the indication of a domain zone, but in the modern world these abbreviations are rather an atavism.
An inventor of WWW and HTTP is the British scientist Tim Berners-Li who suggested to use the Internet for simplification of work with documents in the organization where it worked.
To understand what is meant by www and http in the website address and also to understand why they are necessary, it is necessary to glance in the history of worldwide network. The Internet was invented in 1989 as means of storage and data transmission in a hypertext format. The hypertext is meant as a way of the organization of information by creation of communications and links here. In a general sense the hypertext is any text incorporating links to other texts, for example, the encyclopedia. The website represents a set of hypertext documents too.
What is WWW?
Tim Berners-Li also became the author of the first-ever website on which the guides to creation of servers and use of browsers were collected.
Technologies in the early nineties only developed of the last century therefore for different requirements different servers were used. For example, there were separate servers for file transfer (ftp), for sending e-mail (mail) and for access to hypertext documents (www). Reduction of WWW is formed from World Wide Web that is translated as the World wide web. Very often World wide web is confused with the Internet though actually the Internet is just a set of the computers united in the general network, and WWW – one of transmission media of data. As World wide web is the most popular way of use of the Internet, the www prefix in the website address is often lowered as by default it is meant that the user is interested in the hypertext.
Hypertext protocol
As for HTTP, this abbreviation is formed by reduction of the concept HyperText Transfer Protocol too, that is "hypertext transfer protocol". The certain coding standard and data processing allowing users to browse web pages in the form of hypertext documents means. The http protocol works according to the following scheme: the client forms request and addresses it to the server which processes this request and sends to the client result. Over time http began to be applied not only to the hypertext, but also to other data types therefore modern browsers automatically use it if other is specially not specified, for example, the file transfer protocol of ftp.
