When two or more computers are connected with each other, we call it a computer
            network. The 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 the 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.



                      USES OF INTERNET


            The most extensive uses of Internet are:

            E-mail (Electronic mail): It is an online communication system.

            E-mail  enables  us to send and receive  messages  to  people
            anywhere around the world within a matter of seconds.
