What is a Computer Network?

In general terms, a network is an interconnected group of people or objects capable of sharing information with one another. A computer network implies a group of computers (and other technology related devices such as printers, tablets and phone systems) that are connected together using physical media (wiring) or using various wireless protocols.

A computer network consists of nodes. Each node refers to a specific computer or device using the network. The network also consists of links – the physical connections that carry messages between various nodes.
