A pulley and belt is most likely referring to a pulley which is driven by a belt on a vehicles engine. There can be a variety of pulleys e.g. Power Steering pully on the power steering pump, alternator pulley, water pump pulley, etc. The belt is often called a serpentine belt or accessory belt and wraps around these pulley which run your accessories, if the belt breaks your vehicle will lose the accessories in which it powers. It should be noted that the accessory belt is diffent from the timing belt. The timing belt keeps the engine in time and will not go into details about how it does so as the above answer is sufficient enough for the question asked.
A common example of a pulley is a flagpole pulley system, where a rope is used to raise and lower a flag. The pulley helps to reduce the amount of force required to lift the flag by distributing the load.

No it is not. A belt, for example, goes around a pulley.
An example of a fixed pulley is a flagpole. The pulley is attached to the top of the pole, and the rope passes through it to help raise and lower the flag. The pulley remains stationary as the flag is moved up and down by pulling on the rope.
An example of a pulley in the bedroom could be a ceiling fan. The mechanism that controls the speed and direction of the fan is typically operated using a pulley system.

A pulley is used to move a heavy weight. You can use a pulley to lift something that you can't lift alone.
An example of a movable pulley is a flagpole. When you pull down on one end of the rope, the pulley at the top of the flagpole moves with the flag, making it easier to raise and lower the flag.

A fixed pulley is a wheel and axle attached to an anchor point that does not move. An example of this is in a single pulley system where the rope goes up to a hanging pulley, over the wheel of the pulley and back down to the ground again.
