                           COMPUTER NETWORK

                 A computer network is a collection of computers and their peripheral devices (the network’s

                 components)  connected by  communication  links (wired or wireless) through which data  is
                 transferred in the form of signals. In other words, a network is defined as a group of devices that
                 are linked together to share information, data and resources.

                 Note that a computer which is not connected to any network is known as a standalone computer
                 and a computer connected to a network is known as a node or workstation.



                           NEED OF COMPUTER NETWORKING


                 Networking is a way of getting all the devices
                 to  communicate  with each other and use
                 the same data  files and resources through
                 a physical  pathway  called the  transmission
                 medium. This connection between devices can
                 be either wired or wireless. Network serves the
                 following important purposes:

                   It allows information  or files  to  be  shared
                   among other computers in the network.
