Gateway
A gateway is an internetwork device which joins different network protocols together. It woods on all seven layers of OSI model. Gateways are also known as protocols converters. Gateway can accept a packet formatted for one protocols and convert the formatted packet into another protocols. Similarly a gateway can forward packets across different networks that may also use different protocols frequency. If network a is a token ring network using TCP/ IP and network B is a newel Netware network a gateway can relay frames between the two. This means that a gateway has the ability of translating between frame formats but also different protocols.
