A single pulley system is simple. It's just when a pulley has
just one wheel and carries less of a load.
describe a single pulley system
A double pulley system is simple. Instead of one wheel like the single pulley system has, the double pulley system has two wheels and carries more heavier loads than the single pulley system can hold.
A single pulley system is used to change direction of the pulling force line.
A single fixed pulley is a simple machine that only changes the direction of the force applied, not the amount. An example is the pulley in window blinds.
When you pull up the flag you pull it up by the rope. The rope has a pulley on it. So the actual poll is not a pulley but it has a pulley system on it

Double pulley systems are different from the one pulley system because the weight is now attacked to a pulley instead of an anchor. Another pulley is used to take some of the weight. A two pulley system only requires half the effort as a single pulley system.

Single Pulley
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.
One single fixed pulley cannot give any mechanical advantage. It can only redirect the direction of the applied force.
