Ethernet (10base5, or 10base2) is shared media (everyone gets everyone's
traffic). A hub (10baseT) does the same (it delivers everyone's traffic to
everyone). Therefore it runs at a single speed (10 or 100) and it is half
duplex (If I talk, you must be quiet). A switch delivers traffic only
(with some exceptions) to the port that needs to see it (based on MAC
address). It can also buffer the packets, so it can do both 10Mb and 100Mb
as well as full duplex.
