Introducing a particular address in the search bar of your browser, almost no one thinks about the value of www and http strange abbreviations.
They are considered an inherent part of the same website address, as well as an indication of the blast zone, but in the modern world, these abbreviations are probably atavism.
The inventor of WWW and HTTP is a British scientist Tim Berners-Lee, suggested the use of the Internet to facilitate the handling of documents in an organization where he worked.
To understand the meaning of the www and http in the addresssite and find out why they are needed, it is necessary to look into the history of the World Wide Web. The Internet was invented in 1989 as a means of data storage and transmission in hypertext format. Under the hypertext here means a way of organizing information by building relationships and links. In a general sense hypertext is any text that incorporates links to other texts, such as Encyclopedia. Web site also is a set of hypertext documents.
What is the WWW?
Tim Berners-Lee also became the author of the world's first site on which were collected guidance on the creation of servers and browsers use.
Technology in the early 90-ies of the last centuryonly evolved, so the different needs of different servers used. For example, there were separate server for file transfer (ftp), to send an e-mail (mail) and for access to hypertext documents (www). Reducing WWW formed from the World Wide Web, which translates as the World Wide Web. It is often confused with the World Wide Web internet, although in fact the Internet - it's just a set of computers connected to the general network and the WWW - one of the means of communication. Since it is the World Wide Web is the most popular way of using the Internet, the www prefix in the address of the site is often omitted, since by default means that the user is interested in hypertext.
As for HTTP, then this abbreviation alsoformed by reducing the notion of HyperText Transfer Protocol, ie, "Hypertext Transfer Protocol". There is a view of a certain standard of coding and processing of data, allowing users to browse the web in the form of hypertext documents. Http protocol works as follows: the client generates a request and address of the server that handles the request and sends the client the result. Over time, http began to be applied not only to the hypertext, but also for other types of data, so modern browsers automatically use his name, unless specifically indicated otherwise, for example, ftp file transfer protocol.
