6. A router is a hardware device that connects two or more networks and acts as a gateway between networks. It is a special intelligent network device that reads the address in each packet and then decides how to transmit it. It can understand different protocols, such as the Ethernet protocol used by the LAN and the TCP/IP protocol used by the Internet. In this way, the router can analyze the destination addresses of packets from different types of networks, translate the addresses of non-TCP/IP networks into TCP/IP addresses, and vice versa, and then, according to the routing algorithm selected, send each packet to a specified location according to the best route. Routers can connect non-TCP/IP networks to the Internet.
