The entrance and exit to a communications network or system; a device or set of functions that facilitate electronic access by users to remote services or systems and vice versa. In data networks, gateways are typically a network node that connects otherwise incompatible networks. Gateways are commonly used to connect computers on one network, say a token-ring network, with those on a long-distance network. A gateway may be used to interface between two incompatible electronic mail systems or for transferring files from one system to another.
