World Wide Web
The World Wide Web (commonly abbreviated as "the Web") is a system of interlinked hypertext documents accessed via the Internet.
With a Web browser, one can view Web pages that may contain text, images, videos, and other multimedia and navigate between them using hyperlinks.
Using concepts from earlier hypertext systems, the World Wide Web was begun in 1992 by the English physicist Tim Berners-Lee, now the Director of the World Wide Web Consortium, and Robert Cailliau, a Belgian computer scientist, while both working at CERN in Geneva, Switzerland.
The World Wide Web enabled the spread of information over the Internet through an easy-to-use and flexible format. It thus played an important role in popularizing use of the Internet, to the extent that the World Wide Web has become a synonym for Internet, with the two being conflated in popular use
How it works
The terms Internet and World Wide Web are often used in every-day speech without much distinction. However, the Internet and the World Wide Web are not one and the same. The Internet is a global data communications system. It is a hardware and software infrastructure that provides connectivity between computers. In contrast, the Web is one of the services communicated via the Internet. It is a collection of interconnected documents and other resources, linked by hyperlinks and URLs.
Viewing a Web page on the World Wide Web normally begins either by typing the URL of the page into a Web browser, or by following a hyperlink to that page or resource. The Web browser then initiates a series of communication messages, behind the scenes, in order to fetch and display it.
First, the server-name portion of the URL is resolved into an IP address using the global, distributed Internet database known as the domain name system, or DNS. This IP address is necessary to contact and send data packets to the Web server.
History
This NeXT Computer used by Sir Tim Berners-Lee at CERN became the first Web server.A NeXT Computer was used by Berners-Lee as the world's first Web server and also to write the first Web browser, WorldWideWeb, in 1990. By Christmas 1990, Berners-Lee had built all the tools necessary for a working Web the first Web browser (which was a Web editor as well), the first Web server, and the first Web pages which described the project itself.
The first server outside Europe was set up at SLAC in December 1991.
The World Wide Web had a number of differences from other hypertext systems that were then available. The Web required only unidirectional links rather than bidirectional ones. This made it possible for someone to link to another resource without action by the owner of that resource..
On April 30, 1993, CERN announced that the World Wide Web would be free to anyone, with no fees due. Coming two months after the announcement that the Gopher protocol was no longer free to use, this produced a rapid shift away from Gopher and towards the Web. An early popular Web browser was ViolaWWW, which was based upon HyperCard.
