How does the Audi A4's turbocharged engine provide optimal performance?

I have heard that the Audi A4 comes with a turbocharged engine, but I am not sure how it differs from a normal engine. Can someone explain how it works and why it is beneficial?

The turbocharged engine in the Audi A4 is able to compress more air into the engine to increase power and improve performance. This is achieved by using exhaust gas to turn a turbine, which then pumps more air into the engine. Overall, this results in a more efficient and powerful engine.
