What is a communication network?



A network is a group of interconnected systems sharing services

and interacting by means of a shared communications link.

A network, therefore, requires two or more individual

systems with something to share (data).





Communication network is a system of computers linked together. Among these computers is possible to transfer information easily and fast. Information is possible to transfer between computers, which are not connected to the network on media such as floppy disc, magneto-optical tape and optical disc.
