ELI5: supercharger vs. turbocharger

I've heard of turbo lag and understand that turbos inject air into carburetor.  Don't know much past that.  How do they work? What are the differences?  Which is used in different scenarios?

Supercharger is engine driven, meaning it forces air into the engine using a belt driven charger.

Turbo is air driven, forces exhaust air in the charger to force more air into the engine.

Turbo lag is from the time your push the petal until the turbo "spools" up with air and forces the air into the engine intake.

Superchargers do not have lag since they are driven by belts which react on demand.
