Sorry, morphine, but you got it wrong.
Switches are intelligent hubs:
Hubs receive a signal from one device on the network and broadcast the signal to every other connected device, it goes back and forth like that, with a bunch of collisions, since only one packet pases through at a time.
Switches, however, get the MAC and IP addresses of each connected device, so that when one device sends a packet, it is sent specifically to the destination device.
If you look on the specs of an 8-port 100Mbps switch, it will say that the max throughput is 400Mbps, because if it so happens that four of the computers send packets to the other four connected devices, each connection will be a dedicated 100 Mbps.
Hope this alleviates the confusion
