A '''network card''' (also called '''network adapter''', '''network interface card''', '''NIC''', etc.) is a piece of [[computer hardware]] designed to provide for [[computer communication]] over a [[computer network]].
The card implements the electronic circuitry required to communicate using a specific [[physical layer]] and [[data link layer]] standard such as [[ethernet]] or [[token ring]]. This provides a base for a full network [[protocol stack]], allowing communication among small groups of computers on the same [[LAN]] and large-scale network communications through routable protocols, such as [[Internet Protocol|IP]].
