Well, they sort of do the same thing but the major difference is that
a supercharger forces outside air down the engine's throat (in a carburated
engine, the supercharger sits above the carb), while a turbocharger
increases the manifold pressure by drawing air in through the (carb,
throttle, whatever) and then injecting it back into the intake manifold.

A turbocharger is more complicated, but allows better throttle control
at lower power ranges.
