Write a short note on WWW

WWW: The World Wide Web (WWW or W3) is an information space where documents and other web resources are identified by URLs, interlinked by hypertext links, and can be accessed via the Internet. It was created by Timothy Berners Lee in 1989 at CERN in Geneva. 

WWW works on client- server approach. Following steps explain how the WWW works: 

1. User enters the URL (eg.: http://www.wikipedia.org) of the web page in the address bar of web browser. 

2. Then browser being a client, requests the Web Server for the Web Page corresponding to www.wikipedia.org . 

3. Then web server receives request using HTTP protocol and makes a search for the requested web page. If found it returns it back to the web browser. 

4. Now the web browser receives the web page, interprets it and displays the contents of web page.
