What is the difference between a windqw A/C and a split A/c/

what is the difference between a windqw A/C and a split A/c/
I'm searching 4 answer myself.

Window units go in your window and vet to the outside. Mini split systems hang on the wall and Have there own outdoor unit.

In my area a split system is a system that has a coil inside the home that works with an air handler that blows air through the coil. The coil has two lines running to a unit on the outside of the home that pumps the freon into the coil on the inside.

This is a very simple example.

Are they asking about regular ac units? Or sayno, chigo mr slim units?
