Switching is a general term for technologies that, based on the needs of both ends of a communication network, route information to the appropriate routing, either manually or automatically. Switches can be categorized as wide area network (WAN) switches or local area network (LAN) switches, depending on their location. A WAN switch is a device that performs information exchange within a communication system, operating at the data link layer. A switch has multiple ports, each with bridging capabilities, connecting a LAN or a high-performance server or workstation. Switches are sometimes referred to as multi-port bridges.
A network switch is a device that expands a network, providing more connection ports within a subnetwork to connect more computers. With the development of the communications industry and the advancement of informatization in the national economy, the market for network switches has steadily grown. They offer high cost-effectiveness, high flexibility, relative simplicity, and ease of implementation. Ethernet technology has become the most important LAN networking technology today, making network switches the most popular type of switch.
Switch is the English name for a switch. This product is an upgrade from the original hub and appears similar in appearance to a hub. Since both ends of the communication need to transmit information, the technology used to send the information to be transmitted to the corresponding router that meets the required standards is switch technology. In a broad sense, the device that realizes the information exchange function in the communication system is a switch.
