A switch is the core component of a network - the device that all the computers in a network connect to. Compared to a hub, a switch is significantly faster, as it addresses data to ensure that it is sent only to the correct computers. The switch is designed to handle both 10 Mb/s and 100 Mb/s in the same network.
