Entering an address in the browser's search bar, almost no one thinks about the meaning of the strange abbreviations www and http.
They are considered as an integral attribute of the site address, as well as the indication of the domain zone, but in the modern world these abbreviations are more of an atavism.
The inventor of WWW and HTTP is British scientist Tim Berners-Lee, who offered to use the Internet to facilitate work with documents in the organization where he worked.
To understand what www and http mean in the addressSite, and also to understand, what for they are necessary, it is necessary to glance in history of a world network. The Internet was invented in 1989 as a means of storing and transmitting data in hypertext format. Hypertext refers to the way information is organized by building links and links. In general, hypertext is any text that includes links to other texts, for example, an encyclopedia. The Internet site is also a set of hypertext documents.
What is WWW?
Tim Berners-Lee also became the author of the world's first site, which was collected guidelines for the creation of servers and the use of browsers.
Technology in the early 90-ies of the last centuryOnly evolved, so for different needs, different servers were used. For example, there were separate servers for transferring files (ftp), for sending e-mail (mail) and for accessing hypertext documents (www). The reduction of the WWW is formed from the World Wide Web, which translates to the World Wide Web. Very often, the World Wide Web is confused with the Internet, although in reality the Internet is just a set of computers connected to a common network, and the WWW is one of the means of data transmission. Since the World Wide Web is the most popular way of using the Internet, the www prefix in the site address is often omitted, because by default it is implied that the user is interested in hypertext.
As for HTTP, this abbreviation tooIs formed by reducing the concept of HyperText Transfer Protocol, that is, the "hypertext transfer protocol". There is a certain standard for encoding and processing data, allowing users to view web pages in the form of hypertext documents. The http protocol works as follows: the client forms a request and sends it to the server that processes this request and sends the result to the client. Over time, http was used not only for hypertext, but for other types of data, so modern browsers automatically use it, unless otherwise specified, for example, the ftp file transfer protocol.
