                 The process of connecting computers and peripheral devices with each other, so that they can
                 exchange data is called computer networking. To do networking, various types of hardware
                 devices, protocols and software are required.

                     COMPUTER NETWORK
                 The computer network is a system of interconnected computers that
                 can communicate with each other. It allows us to share the resources

                 such as computers and peripherals.                                               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 may be linked through
                 the cable, hub, switch, NIC (Network Interface Card), modem or router. There are different kinds
                 of computer networks that work in different ways. Networks may be very small and simple as

                 in a room or they may be complex as a global network like the Internet. There may be wired or
                 wireless connection between computers on the network.
                     NEED FOR COMPUTER NETWORK

                 Computers and other devices connected on a network help in:
                    Resource Sharing: It help the users to share files and hardware devices such as printers,
                    scanners, etc.

                    Communication: It helps us to communicate with others through e-mail, video conference,
                    instant messaging, etc.
                     ADVANTAGES OF COMPUTER NETWORK

                 The advantages of computer network are:
                    The information can be easily shared by the people.
