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.
Internet
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.
