a directional advantage
Single fixed pulley
A pulley can either change the direction or the force, but not both. Since a single fixed pulley makes an object go up when pulled down, it has changed direction. So it can't also change force.
It allows you to pull from a convenient position. For instance you can raise your washing line or flag whilst standing on the ground instead of having to climb the support pole.

Thew pulley changes the direction of the effort force.
Nothing, really. A slight loss due to friction. If the pulley is fixed to the load, then there is a 2:1 advantage.
single fixed pulley, single movable pulley and single fixed and movable pulley. :-)
Mechanical advantage of a fixed pulley
One single fixed pulley cannot give any mechanical advantage. It can only redirect the direction of the applied force.
A single pulley alters the direction of the input but confers no mechanical advantage.
