Click on the Related Link below and scroll down the page. There are photos of the front of a motor. The belt is a long, thin, black rubberized band -- it's one long loop. The pulleys are round. The belt is placed on top over the pulleys. One pulley can be moved a little so that the belt can be made tighter or loser.

Why all that stuff? When the motor runs it turns one of the pulleys, and that makes the belt move (cause its tight on the pulley) and the belt moving causes all the other pulleys to turn. So the fan turns to cool the radiator.. So the alternator turns and makes electiricity to charge the battery. Etc. Etc.

A pulley is a wheel with a groove and a the belt is what runs through those grooves which spins the pulley. The pulley spins which turns a pump in a Power Steering pump or coil in a alternator.
