Routers operate at the Network Layer (layer 3) of the OSI model and forward packets across computer networks based on the information in their routing tables. Bridges operate at the Data Link Layer (layer 2) and forward frames between network segments, switches also operate at the Data Link Layer (layer 2) and forward frames to their destination port, and hubs simply forward all network traffic to all connected devices.
