| Mind map of World Wide Web |
The World Wide Web is a system of Internet
servers that support specially formatted documents. The documents are formatted
in a markup language called HTML (Hyper Text Markup Language) that supports
links to other documents, as WELL as graphics, audio, and video files. This
means you can jump from one document to another simply by clicking on hot
spots. Not all Internet servers are part of the World Wide Web.
Individual document pages on the World Wide
Web are called web pages and are accessed with a SOFTWARE APPLICATION running
on the user's computer, commonly called a web browser.
Tim Berners-Lee, a British computer scientist
and former CERN employee is the inventor of the Web. He was knighted in 2004 by
Queen Elizabeth II for "services to the global development of the Internet.
The terms Internet and World Wide Web are
often used without much distinction. However, the two things are not the same.
The Internet is a global system of interconnected computer networks. In
contrast, the World Wide Web is one of the services transferred over these
networks. It is a collection of text documents and other resources, linked by
hyperlinks and URLs, usually accessed by web browsers, from web servers.
The primary function of a web server is to
deliver web pages in response to client requests. This means delivery of HTML
documents and any additional content that may be included by a document, such
as images, style sheets and scripts. And the primary purpose of a web browser
is to bring information resources to the user ("retrieval" or
"fetching"), allowing them to view the information
("display", "rendering"), and then access other information
("navigation", "following links").
World Wide Web is a World Wide Market. It
is a new way of selling. More and more customers expect to find news on the
web. It exactly can become a symbol of social today, the advantages it brings
to people are always going up.
