                                      Protocol



                 The process of connecting computers and peripheral devices with each other, so that they can
                 exchange data is called computer networking. Various hardware devices, protocols and software
                 are  required for networking. In this chapter  you are  going learn  about  networking  and the
                 concepts related to computer networking.

                     COMPUTER NETWORK

                 A computer  network  is a  group  of interconnected  computer  systems  and  other  computing
                 devices.
























                                                           Computer Network
                 The computers on the network can communicate with each other as well as work independently.
                 Each computer in a network is called a node. The computers in the network maybe linked through
                 a cable, hub, switch, NIC (Network Interface Card), modem or router.
