World Wide Web - The information Universe

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.
