How does quattro all-wheel drive work in Audi vehicles?

I've heard that Audi vehicles have all-wheel drive, but I'm not sure how it works. Can someone explain it to me?

Quattro all-wheel drive in Audi vehicles distributes power between the front and rear axles, constantly monitoring traction to provide maximum grip and control on various road conditions.

As an Audi owner, I can say that the quattro all-wheel drive system provides unparalleled performance and handling on all types of terrain, making it perfect for both city and off-road driving.
