A router is a hardware device that connects two or more networks. It acts as a gateway between networks. It is a dedicated intelligent network device that reads the address in each data packet and then decides how to transmit it. Routers can be divided into backbone routers (core routers), enterprise-level routers, and access-level routers.   Generally, backbone routers have multiple optical ...
