A fixed pulley is a pulley that is attached to a structure and does not move;changes the direction of the effort force used to life a load by a person or a spring scale and if you use a spring scale then you will need a person to pull the spring scale done to see how far she/he pull it
A moveable pulley is a pulley that supports the load and is not fixed in place;reduces the amount of effort force needed to pull to lift the load when she/he pulls the spring scale then it will tell she/he pulls it.
Fixed pulleys have their center point fixed. i.e. they can only have rotary motion and no linear movement. Movable pulleys do not have their center point fixed, and are free to have translatory as well as rotary motion
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.
A moving pulley is a wheel on an axle designed to support movement without a center point being fixed. A fixed position pulley does not change positions and rotates only in one direction.

A compound pulley
A fixed pulley is the only pulley that when used individually, uses more effort than the load to lift the load from the ground. The fixed pulley when attached to an unmovable object e.g. a ceiling or wall, acts as a first class lever with the fulcrum being located at the axis but with a minor change, the bar becomes a rope. The advantage of the fixed pulley is that you do not have to pull or push the pulley up and down. The disadvantage is that you have to apply more effort than the load
A compound machine that consists of both fixed and movable pulleys is a fixed pulley. This machine changes the direction of the force on a rope or belt that moves along its circumference.
The 4 moveable joints are called the Ball-and-socket, Hinge, Pivot, and Gliding joints.
A healthy knee is a highly moveable joint. It has the capacity to move forward some, back a lot, and also side to side.

Yes. The IMA of a movable pulley is 2.
That is not always true. Sometimes a fixed pulley is more useful.
There are fixed, moveable, and compound pulleys.
