Multizone vs. VAV?

Can someone clarify the difference between a multi-zone and VAV air system? It seems they achieve more or less the same effects--ability to heat or cool multiple zones simultaneously, both require relatively extensive ducting. Is the difference that in a VAV system the air is mixed and then sent to its destination and in a multizone system the air is mixed at the terminal? Or...???
