A turbo and a supercharger force more air into your engine, allowing more fuel in too (you get the same fuel:air ratio, just at a higher pressure), thus increasing the power you can get out of a set volume cylinder.

A supercharger runs off a physical belt attached to the engine, whereas a turbo is powered by exhaust gasses passing through a turbine. Because of this, a supercharger essentially saps some energy from your engine because it has to move the belt, and a turbo will experience a ‘lag’ because it takes time for the exhaust gases to spin the turbine faster as you put your foot down.
