Each port on a switch corresponds to a device connected to the network, and data is transmitted through these ports to facilitate communication between devices. Switch ports typically use Ethernet cables (such as Cat5e or Cat6 cables) to transfer data. Switches have many ports, and when data arrives at any port, the. A network switch (also called switching hub, bridging hub, Ethernet switch, and—by the IEEE — MAC bridge) is networking hardware that connects devices on a computer network by using packet switching to receive and forward data to the destination device. A network switch is a multiport network. They connect multiple devices, such as computers, wireless access points, printers, and servers; on the same network within a building or campus. It operates at the data link layer (Layer 2) of the OSI model, though some advanced switches can operate at higher layers, such as Layer 3. A network switch receives data packets.
