Switching is a general term for the technology that uses manual or automatic equipment to transmit information to the corresponding route that meets the requirements according to the needs of both ends of the communication. Switches can be divided into WAN switches and LAN switches based on different working locations. A wide area switch is a device that performs information exchange functions in a communication system. It is applied at the data link layer. The switch has multiple ports, each with bridging capabilities, that can connect to a local area network or a high-performance server or workstation. In fact, switches are sometimes called multiport bridges.

A network switch is a device that expands the network and can provide more connection ports in a subnetwork to connect more computers. With the development of the communications industry and the advancement of informatization of the national economy, the network switch market has shown a steady upward trend. It is cost-effective, highly flexible, relatively simple and easy to implement. Ethernet technology has become the most important LAN networking technology today, and network switches have become the most popular switches.
