Quizplus · Accepted Answer

Routers are networking devices that operate at the internet layer (layer 3) of the OSI model. They are responsible for forwarding data packets between different networks, using different protocols. Routers may also be referred to as TCP/IP gateways, as they help to route traffic across different TCP/IP networks. Routers typically make forwarding decisions based on the destination IP address in the packet header.
