Fixed Pulley:
A fixed pulley’s wheel and axle stay in one place. A good example of a fixed pulley is a flag pole: When you pull down on the rope, the direction of force is redirected by the pulley, and you raise the flag.
Movable Pulley:
A movable pulley is a pulley that is free to move up and down, and is attached to a ceiling or other object by two lengths of the same rope. Examples of movable pulleys include construction cranes, modern elevators, and some types of weight lifting machines at the gym.

Answer and Explanation:
Fixed Pulley Systems : The pulley in such a type of system cannot change its place when the motion of rope or string takes place like in the case of the flagpole where the pulley cannot be moved up and down.
Movable Pulley Systems : In this type of systems the pulley can be repositioned and move along the rope systems.
