What is a network?
A computer network is a set of computers connected together. In order to be considered a network, at least two or more computers must be connected together, and they must be sharing resources. A computer network is also commonly referred to as a data network.
The network may be connected via cables, telephone lines, radio waves, satellites, or infrared light beams. Its primary function is to facilitate the transfer of data, including transmitting, receiving and exchanging data, voice and video traffic.
The two most common types of networks are Local Area Network (LAN) and Wide Area Network (WAN).
