Ideal Mechanical Advantage ( IMA ) is the mechanical advantage of a machine that has no friction. This means that the work's output force is less than the work of the the input force
There are no machine that have zero friction. some has a small amount of friction so that the Ideal mechanical advantage is very close to mechanical advantage.
Note: Hammer or a screw driver does not have a sliding part so therefore it has almost no friction at all.

Friction:
Friction is the force that opposes the relatice motion of an object or you could say it like the resistance that one surface or object encounters when its rubbing the surface over another. A incline plain will have lots of friction because the the object is rubbing against the suface of the incline plain the whole time.
