Half-duplex means that only one side can be talking at a given time.
When both sides try talking at once, you get a collision. Both sides
then wait a (more or less) random period of time, then try talking
again. The wait interval increases (geometrically?) every time
there's another collision, until eventually only one side will be
talking at a particular time.
Full-duplex means that both sides can talk at once. There are no
collisions and no fallbacks.

If you're plugged into a hub, you are using half-duplex. It is not
possible to use full-duplex on a hub, by definition. If you're
plugged into a switch and your NIC supports full-duplex operation,
then your NIC should auto-negotiate to full-duplex (that is, it should
not require any configuration on your part unless something is
wrong). One thing to note: there's no reason all NICs on a switch
_have_ to use full-duplex mode.
