A switch is a device in a computer network that connects devices together. Multiple data cables are plugged into a switch to enable communication between devices in the network. Switches manage the data across a network by transmitting a received network packet to one or more devices. Each networked device connected to a switch can be identified by its network address, allowing the switch to direct the flow of traffic maximising the security and efficiency of the network. TP-Links Switches range from simple desktop hubs to offer more wired connections, all the way through to enterprise level switches with Level 2 and Level 3 Management options.
