This section provides a quick introduction of WWW (World Wide Web) and the first Web server developed by Tim Berners-Lee in 1991.
What Is WWW (World Wide Web, the Web)? -
WWW is an information network where users can view multi-media information with hyper links to click and view additional information.
WWW was developed by Tim Berners-Lee at CERN (European Organization for Nuclear Research) in 1991.
Main elements of WWW are:
HTTP (HyperText Transfer Protocol) - A communication protocol to allow Web browsers to send requests and Web servers
to return responses with HTML documents and other types of data.
Web Server - A communication server program listening for incoming HTTP requests and returning HTML documents and other types of data.
Web Browser - A communication client and HTML display program sending HTTP requests to Web servers
and displaying received HTML documents to end users.
HTML (HyperText Markup Language) - A markup language that organize information and hyper links with embedded tags.
URL (Uniform Resource Locator, previously Universal Resource Locator) - An identification protocol to allow every document
on the Web to be uniquely identified by an address string.
Hyper Link - An anchor in Web document that links to the URL of another document on the Web.
When users click the anchor, the Web browser will automatically retrieve and display the other document.
The world's first Web page was published at this URL: http://nxoc01.cern.ch/hypertext/WWW/TheProject.html
by Tim Berners-Lee on August 6, 1991.
