I'm coming in at the end of this thread so I apologize if I'm stating something that someone else already covered. I wanted to nitpick a little, perhaps because I need more coffee, as usual,
A hub is a layer one technology since it's simply a multiport physical repeater. It is truly shared. As Mike mentions, what one device sees all others will see. A bridge is a layer two technology that limits the traffic seen on each port. A bridge--or switch--will forward broadcast/multicast traffic out all ports. It will also forward unicast traffic destined for unknown destinations. Once it has populated its bridge table, an endstation on a given port will only see broadcast/multicast traffic and traffic that is destined for it specifically. It will not see unicast traffic destined for hosts on other ports.
