A computer network is an electronically interconnected set of computers that are able to communicate and share resources amongst each other. Various devices such as hubs, switches and routers are used to interconnect different computers either wired or wirelessly. To enable intercommunication, a set of rules (communication protocols) are implemented, and these govern the exchange of information within the network. This technology plays a vital role to individuals and organizations but also has downsides, as with other forms of technology.

Different networks can differ in designs and transmission media used to transmit their signals and while some may use copper wires, others may use fiber cables or wireless communication.
