The "Web", short for "World Wide Web" (which gives us the acronym www), is the name for one of the ways that the Internet lets people browse documents connected by hypertext links.
The concept of the Web was perfected at CERN in 1991 by a group of researchers which included Tim-Berners Lee, the creator of the hyperlink, who is today considered the father of the Web.
The principle of the Web is based on using hyperlinks to navigate between documents (called "web pages") with a program called a browser. A web page is a simple text file written in a markup language (called HTML) that encodes the layout of the document, graphical elements, and links to other documents, all with the help of tags.
Besides the links which connect formatted documents to one another, the web uses the HTTP protocol to link documents hosted on distant computers (called web servers, as opposed to the client represented by the browser). On the Internet, documents are identified with a unique address, called a URL, which can be used to locate any resource on the Internet, no matter which server may be hosting it.
