How does Audi A8's adaptive air suspension work?

I've noticed some of my friends have been talking about the adaptive air suspension on the Audi A8. I'm not very familiar with how it works and was wondering if someone could explain it to me in simple terms.

The adaptive air suspension on the Audi A8 uses an air spring and air suspension system to actively adjust the suspension of the vehicle based on driving conditions, providing a smooth and comfortable ride. It can also be adjusted manually for a more personalized driving experience.
