When two or more computers are connected with each other, we call it a computer
                 network. Internet is a vast network of computers connected together, which makes

                 communication  between  them  possible.  The term  ‘Internet’  is  derived  from the
                 word internetworking. It connects millions of computers across the world by means
                 of cables, telephone wires or certain wireless media of communication.




























                          HISTORY OF INTERNET


                 The history of the Internet starts with the development of electronic computers in

                 the 1950s. In the 1960s, the first computer was developed, supported by the United
                 States Department of Defence. It was called ARPANET and it was meant to connect

                 only a few computers with each other.

                 ARPANET was developed  with the  aim  of sharing information  on research and
                 development and was used only by government officials and scientists. It was later
                 opened for the universities to spread education and share their resources.

                 The network rapidly grew bigger and by the 1990s, a modern version of the network,

                 the Internet, as we know it today, had evolved thinking about life without the use of
                 the Internet has become difficult.
