A computer network is a series of computers, called hosts, and software connected by means of a telecommunications system that allow groups of individuals to share data, printers, communications systems, electronic mail, and other resources.
A computer network is
|“||a set of connected devices and communication facilities, including more than one computer, with the capability to transmit computer data among them through such communication facilities.||”|
The host computers may be personal computers, commonly used in homes and businesses, or they may be larger. With connections between hosts ranging from local area networks to satellite-mediated, long-haul networks, data in the form of text, voice, and video, can be stored, modified, and exchanged by anyone anywhere on the planet.
