Switch

12:55 AM in

Switch is a device used in the data link layer. Same with hubs, switches connecting multiple hosts to the network. But unlike a hub, a switch can immediately forward the message to the destination without the message to all hosts. When a host sends a message to another computer within the scope of the switch, the switch receives and translates the context of the message to read your
MAC address.

Switch is best to compare with the cube, because you can change configuration of VLAN in each port enables the data through the specific port.
and it is not easy to overlook the collusion bit attraction at its centre is the very high collusion, the price is more expensive, but good for the quality of your network.
