What is the difference between a turbocharged vs supercharged engine in the Audi A6?

I'm looking to purchase an Audi A6 and I'm confused about the difference between a turbocharged and supercharged engine. Can someone provide a clear explanation?

Both turbocharged and supercharged engines are designed to increase the power and performance of your Audi A6. The main difference is in how they achieve this boost. Turbochargers use exhaust gases to power a turbine, while superchargers are driven directly by a belt connected to the engine.

A turbocharged engine can provide more power and better fuel efficiency, as the exhaust gases used to power the turbine is essentially recycled energy. On the other hand, a supercharged engine tends to have a more immediate and consistent power delivery, which can be beneficial for driving in city traffic.
