Need for Networking
                 As we have learned, computer networking is mainly used for resource sharing and transferring information. Let us learn
                 about some of the needs for computer networking.

                 Share Resources
                 We can share hardware and software resources by connecting computers through networking. Peripherals such as
                 printers and scanners, the CPU, and RAM are some examples of hardware. Software resources may include system
                 software and application software.






















                 Communication

                 The  exchange  of  information  between  nodes  in  a  network  is  simplified  by  connecting
                 computers through a network. A network requires a variety of network devices, including
                 modems, routers, switches, and bridges, each of which serves a distinct purpose in the network.

                 Access to remote databases
                 Today, every person can easily access databases from remote locations, such as when booking tickets, paying bills,
                 checking results, etc., because of networking. When we book a train ticket, we indirectly interact with the database of
                 the railways. Networking plays a vital role in accessing remote databases. The computer on which the databases stored
                 is known as database server.

                 Requirements of a Network

                 Let us now look at what are the requirements of a network. Any network includes:
                 Ð ÐComputer: Minimum two computers, one for server and other for client workstation, are required to form a network.
