    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
                     words interconnection and networks. 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.
