                                   Wireless Networking Technology               Protocol

            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 which
            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 maybe 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 share files and hardware devices such as printers, scanners,
               etc.
                Communication: It helps us 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.
