Differentiate between supercharging and turbocharging in IC engines.

Both methods increase engine power by forcing more air into cylinders, but differ in power source. A supercharger is mechanically driven by the engine crankshaft via belt or gear, providing instant response but consuming engine power (parasitic loss of 5-10%). A turbocharger uses exhaust gas energy to drive the compressor, recovering waste energy but suffering from turbo lag at low RPMs. Turbochargers offer better fuel efficiency, while superchargers provide linear power delivery preferred in performance applications.
