The web is structured in a concept of universal leadership; if there is information available, any authorized individual could be allowed to access it, from anywhere in the world. Theweb, more or less, runs on a client-server model. Client is the users terminal and the Server is theterminal (mainframe) that the user is connected to. Not only does a connection exist between theclient and the server, the connections are cross-wired in such a way that clients are connected to eachother and servers are connected to each other. No particular unit is the key focus of the wholesystem. If there is a technical difficulty affecting any server in the system, it does not affect thesystem as a whole. Since there is no one main system, no one can pinpoint a geographical location, forthe web. No matter where the user is located, a POT line can connect him or her to the globalnetwork. The Web has changed dramatically since its humble beginnings. In 1989, CERN (ConseilEuropeen pour la Recherche Nucleaire), a group of scientists in complex Physics, Engineering andInformation Handling fields, realized the need for a network for fast access of information. Since theyhad the financial resources for setting up such a system, within months, a network was established;using simple browsers, scientists were allowed access into the mainframe and its vast contents. Theywere also given the option of posting their own studies and adding to the material of the database. Inthe early years, hypertext was a crucial component. The browsers were completely text-based andhypertext (a text link) allowed the users to jump from one document to another. Tim Berners Lee ofCERN incorporated the ideas of Ted Nelson (inventor of hyperlink) and soon generated the idea ofThe World Wide Web. As soon as it was opened to the public at the dawn of this decade, the webreceived much acceptance and recognition and the response was tremendous. Since then, th...
