                 The  process of connecting  computers  and  peripheral  devices so they  can  exchange  data  is
                 called computer networking. Various hardware devices, protocols, and software are required for
                 networking. In this chapter, you are going to 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.

                 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 may be linked

                 through a cable, hub, switch, NIC (Network Interface Card), modem, or router.
