An Ethernet switch is a device that connects a plurality of stations in a network. In an Ethernet network (star topology), a switch is a distributor for the data packages. The function is similar to the Hub, with the difference that a switch a direct connections between the devices created, if he is aware of the Port of the data receiver. If not, the "broadcast" Mode is used , the switch sends the data packets to all ports. When the reply packets come back from the receivers, the switch learns the MAC addresses of the data packets and the corresponding port, now it sends the individual data only to the matched receiver. A hub limits the bandwidth of the network by the "broadcast" mode, the switch connect the two stations with the full speed as the end-to-end network connection can support.
