With a hub, all traffic coming into the hub is sent out to ALL ports at once.  A switch adds intelligence and it "learns" what addresses are on which port and only send packets to the one port that they are destined for.  The benefit is that this reduces traffic on the different ports of the hub and can extend the effective bandwidth of a network.  The drawback is that switches are significantly more expensive than hubs.
