What is the difference between Supercharghing and Turbocharging?

Supercharging is the process of providing air to the engine at higher pressure than atmospheric pressure.

Turbocharging is one of the type of supercharging were exhaust gas is use to drive the turbine.

The main function is that if more air is induced then more fuel can be burnt.

The air is sent to a cooler, were the mass of air is increased when cooled, i.e density of the air increases.
