By technical specifications a Turbo Charger is a special type of
supercharger. Supercharger is a generic term, where turbocharger is a
specific term.

Often (outside of engineering circles) the lay public refers to
superchargers, as those which are only belt driven, which is incorrect.

But it isn't friday, and I too will refer (and prefer) to distingush
between the belt driven and exhaust driven ones as superchargers and
turbochargers.
