          We  have  learned  that  a  computer  is  capable  of  storing
          large  amounts  of  information  and  retrieving  it  as  and
          when required. But a single computer cannot hold all the

          information that one needs. In such a scenario, the user
          may need to look for information from some other source.
          Just like humans share news and information with each
          other,  computers  can  also  share  information.  To  share

          information, computers need to be connected together. A group of two or more
          computers connected together that enables sharing of information between them
          is called a Computer Network or simply a Network.


                                                       WHAT IS INTERNET?
                                                       Internet  stands  for  International  Network.  It  is
                                                       the network of computers that connects millions

                                                       of  computers  together,  spawning  the  entire
                                                       world. It is the global storehouse of information
                                                       which enables a user to access information and
                                                       communicate with others easily and quickly.


          HISTORY OF INTERNET

          The concept of computer networks was born in 1969. The Department of Defense,
          USA, set up the first network of computers called ARPANET (Advanced Research
          Projects Agency Network). It was developed to share information about research
          and development in areas of science and technology among scientists all over the

          USA. Initially, it was only used by government officials and scientists. Later on, it
          was granted access to the common public and educational institutions. Over time,


                                                                                                              99
