How does a static discharge differs from a electric discharge?

Static discharge involves the movement of ions as well as electrons.

I believe this answer that each of these two are powered by different things.

It doesn't differ at all, an electric current is electricity that is moving in a current and when static electricity is discharged from an object it creates a current from one object to another

A static discharge is an accumulation of static electricity that discharges when negative electrons connect with the positive protons.
