WORLD WIDE WEB (WWW)

World Wide Web -1989
 
"CERN is a meeting place for physicists from all over the world, who collaborate on complex physics, engineering and information handling projects. Thus, the need for the WWW system arose "from the geographical dispersion of large collaborations, and the fast turnover of fellows, students, and visiting scientists," who had to get "up to speed on projects and leave a lasting contribution before leaving."
CERN possessed both the financial and computing resources necessary to start the project. In the original proposal, Berners-Lee outlined two phases of the project:
First, CERN would "make use of existing software and hardware as well as implementing simple browsers for the user's workstations, based on an analysis of the requirements for information access needs by experiments."
Second, they would "extend the application area by also allowing the users to add new material."
Berners-Lee expected each phase to take three months "with the full manpower complement": he was asking for four software engineers and a programmer. The proposal talked about "a simple scheme to incorporate several different servers of machine-stored information already available at CERN."
Set off in 1989, the WWW quickly gained great popularity among Internet users. For instance, at 11:22 am of April 12, 1995, the WWW server at the SEAS of the University of Pennsylvania "responded to 128 requests in one minute. Between 10:00 and 11:00
 What is World Wide Web?
  • A huge resource of information
  • Logically unified, but physically distributed 
  • Logically unified:  Any one from any where can access the information using a very simple scheme consisting of links & URLs
  • Physically distributed:  The information is stored on Internet-connected computers that are spread all over the globe
Who is Allowed to access the Web?
  • Any one and every one with a computer and a connection to the Internet
  • No nationalistic, ideological, racial, or religious restrictions
  •  In Pakistan, Web is accessible from any city or town that has a phone available
     
The Web is unlike any previous human invention. Because it is a world-wide resource, important to all of the people in the world
How do I visit a Web page?
  1. Turn your computer on
  2. Connect to the internet through a modem or Local Area Network
  3. Launch the browser (which in most cases, will be the Internet Explorer)
  4. Type in the URL of the Web page that you want to visit
