ROUTER network device that forwards packets from one network to another. Based on internal routing tables, routers read each incoming packet and decide how to forward it. Routers work at the network layer (layer 3) of the protocol GATEWAY device that converts one protocol or format to another. A network gateway converts packets from one protocol to another.the gateway functions as an entry/exit point to the network.An earlier name for router. GATEWAY work at the network layer (layer 4) of the protocol.
