A router is a hardware device that connects two or more networks and serves as a gateway between them. It is a specialized intelligent network device that can read the address in each data packet and decide how to transmit it. Routers can support different protocols, such as Ethernet for local area networks and TCP/IP protocols for the Internet. Therefore, it can analyze the destination addresses of data packets from various types of networks, convert non TCP/IP network addresses into TCP/IP addresses, and vice versa. Then, according to the selected routing algorithm, the router transmits the data packet along the optimal route to the designated destination. This allows routers to connect non TCP/IP networks to the Internet.
