Definition
Switch means "open and close" is a network device used for the transmission of electrical (optical) signals. It can provide an exclusive electrical signal path for any two network nodes of the access switch. The most common type of switch is an Ethernet switch. Other common telephone voice switches, Fibre Channel switches and so on.
A Router is a hardware device that connects two or more networks and acts as a gateway between networks. It is a dedicated 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 a local area network, 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, and translate the addresses of non-TCP /IP networks into TCP/IP addresses, or vice versa. Then, according to the selected routing algorithm, each packet is sent to the specified location according to the best route. So routers can connect non-TCP /IP networks to the Internet.
