What is Gateway (telecommunications)?
In computer networking and telecommunications, a '''gateway''' is a component that is part of two networks, which use different [[protocol]]s. The gateway will translate one protocol into the other. A [[router]] is a special case of a gateway. Gateways, also called protocol converters, can operate at any network layer. The activities of a gateway are more complex than that of the router or switch as it communicates using more than one protocol. Both the computers of [[internet]] users that serve pages to users are ''host nodes''. The nodes that connect the networks in between are ''gateways''. These are gateway nodes: *the computers that control traffic between company networks *the computers used by [[internet service provider]]s (ISPs) to connect users to the internet gateway must be implied on larger networks to interconnect them. {{tech-stub}} [[Category:Computer networking]]
