What is a Computer Network?

A computer network is a set of connected computers. Computers on a network are called nodes. The connection between computers can be done via cabling, most commonly the Ethernet cable, or fiber optic cable. Connections can also be wireless; you’ll hear the term wi-fi to describe information sent via radio waves.

Connected computers can share resources like access to the Internet, printers, file servers, and others. A network is a multipurpose connection, which allows a single computer to do more than it could without any connection (what could you really do without an Internet connection?)
