What is World Wide Web

The World Wide Web  
 The  World  Wide  Web (called  WWW or  W3 in short)  is the most popular  and promising   method  of accessing  the Internet.  Main reason for its popularity  is use of a concept  called hypertext.  Hypertext  is a new way of information storage   and  retrieval   that   enables   authors   to  structure  information   in  novel   ways.   An  effectively   designed hypertext  document  can help   locate desired  type of information  rapidly from vast amount  of information  on the Internet. Hypertext   documents  enable  this  by using  a series  of  links.  A  link  is shown  on screen  in multiple ways such as a labeled  button,  highlighted  text, or different  color text than  normal  text  if your computer  has color display,  or author-defined   graphic  symbols.  A link  is a special  type  of item  in a hypertext  document  connecting the document  to another  document  that provides  more  information  about the linked  item. The latter document  can be anywhere  on the Internet (in the same document  in which the linked  item is, on the same computer  in which the former  document   is, or on another  computer  at the other  end of the world).  By “connect”,   we  mean  that  a user simply  selects  the  linked  item (using  a mouse  or key command)  and the  user sees the other  document  on his/her computer  terminal  almost  immediately.The  WWW  uses client server model     and  an  Internet  Protocol  called  HyperText   Transport  Protocol   (HTTP  in short)  for interaction  between computers   on the Internet.Any computer  on the Internet  using the  HTTP protocol, is called a Web Server,  and any computer  accessing  that  server  is called  a Web Client.  Use of client-server   model and the HTTP allows different  kinds of computers  on the Internet  to interact with each other.  For example.  a Unix workstation  mav be a web server  and a Windows  PC may be a web client,  if both of them  use the HTTP  protocol for transmitting  and receiving  information.
