One thing I'd like to add to Jim's explaination is that a MOSFET is a
voltage controlled device and a BJT (bipolar junction transistor) 
(the "normal" type of transistors) are current controlled.  Normally
it takes about 10v to fully turn on a standard MOSFET.

I suggest you pick up any book that describes basic electronics for
additional information.
