How does the Audi A1's turbocharging system work?

I've heard a lot about turbochargers in cars like the Audi A1, but I'm not sure exactly what they do and how they work. Can anyone explain the turbocharging system in the Audi A1?

The Audi A1's turbocharger works by using the engine's exhaust gases to power a compressor, which then forces more air into the engine. This creates a more efficient combustion process, resulting in more power and better fuel economy.
