What is 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 started in 1989 by the English physicist Sir Tim Berners-Lee, now the Director of the World Wide Web Consortium, and later by Robert Cailliau, a Belgian computer scientist, while both were working at CERN in Geneva, Switzerland. In 1990, they proposed building a “web of nodes” storing “hypertext pages” viewed by “browsers” on a network, and released that web in December. Connected by the existing Internet, other websites were created, around the world, adding international standards for domain names & the HTML language. Since then, Berners-Lee has played an active role in guiding the development of Web standards (such as the markup languages in which Web pages are composed), and in recent years has advocated his vision of a Semantic Web.

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.[3] Although the two terms are sometimes conflated in popular use, World Wide Web is not synonymous with Internet The Web is an application built on top of the Internet.

What is a website?

A website (also called an Internet site or a home page in the case of a personal site) is a group of HTML files that are stored on a hosting computer which is permanently connected to the Internet (a web server).

A website is normally built around a central page, called a “welcome page“, which offers links to a group of other pages hosted on the same server, and sometimes “external” links, which lead to pages hosted by another server.

A URL looks something like this:


Let’s take a closer look at this address:

  • http:// indicates that we want browse the web using the HTTP protocol, the default protocol for browsing the Web. There are other protocols for other uses of the Internet.
  • www.commentcamarche.net corresponds to the address of the server that hosts the web pages. By convention, web servers have a name that begins with www., to make it clear that they are dedicated web servers and to make memorising the address easier. This second part of the address is called the domain name. A website can be hosted on several servers, each belonging to the same name: www.commentcamarche.net www2.commentcamarche.net, intranet.commentcamarche.net, etc.
  • /www/www-intro.php3 indicates where the document is located on the machine. In this case, it is the file www-intro.php3 situĂ© located in the directory www.
