A computer network is a collection of computers and devices connected by communication channels. A computer network is a group of computer that are connected to each other for the purpose of communication.

Networks allows authorized user to share data and information stored on other computers of the network.

Computers connected to a network can share equipment like printers, modems etc. They also can share software. This helps to avoid high duplication costs.

Networks can share a single Internet connection. This facilitates communication. People can communicate efficiently and easily via , instant messages, chat rooms, and videoconferencing.

A computer network that physically links two or more computers within a geographic limited area such as a building. The linked computers are called workstations

A Metropolitan Area Network (MAN) covers larger geographic areas, such as cities.

Wide Area Networks (WANs) connect larger geographic areas, such as countries.
