A Basic Introduction To Routers

A router is a hardware device that connects two or more networks, acts as a gateway between networks, and is a dedicated intelligent network device that reads the address in each packet and then decides how to transmit. It can understand different protocols, such as the Ethernet protocol used by a local area network and the TCP/IP protocol used by the Internet. In this way, the router can analyze the destination address of packets coming from various types of networks, and convert the address of the non-TCP/IP network into a TCP/IP address, or vice versa; According to the selected routing algorithm, each packet is transmitted to the specified location according to the optimal route. So routers can connect non-TCP/IP networks to the Internet.
