World Wide Web WWW
In 1989, Tim Berners-Lee invented the World Wide Web. The
Web, as it is commonly called, was originally conceived and developed to meet
the demand for automatic information sharing between scientists working in
different universities and institutes all over the world.
The basic idea of WWW was to merge the technologies of
personal computers, computer networking and hypertext into a powerful and easy
to use global information system. Hypertext is text with links to further
information. With electronic documents, these cross-references can be followed
by a mouse-click, and with the World-Wide Web, they can be anywhere in the
world. There is no need to know where the information is stored, and no need to
know any detail on how it is formatted or organized.
A single document on www is called a web page. Collection of
Web pages, images, videos and other digital resources that is hosted on Web
server is called a website.
Wandering from one document (webpage) to another is called
browsing. Some people do this just for fun, following links just to see what's
there. This is usually called surfing the Web.
Core protocol of World Wide Web is Hypertext Transfer
Protocol which we have already learned, but it also supports several other
Internet protocols and that can be accessed using a single interface i.e.
browser. Almost all protocols available on the Internet are available on the
Web. This creates a convenient and user-friendly environment through which
email, FTP, Telnet, Usenet News etc. can be accessed. Because of this and also
because of the ability of the Web to work with multimedia and advanced programming
languages, the World Wide Web has been the fastest growing and the most
interesting part of the Internet.
