What is the difference between active and passive suspension systems in the Audi A8?

I read that the Audi A8 has an available active suspension system, but I'm not sure how it differs from the standard passive system. Can someone explain the technology and benefits of each in more detail?

The active suspension system in the Audi A8 uses sensors to constantly monitor road conditions and adjust the suspension accordingly, providing a smoother and more comfortable ride. On the other hand, the passive suspension system relies on predetermined settings and does not have the ability to adapt to changing road conditions.
