How does the quattro all-wheel drive system work on Audi vehicles?

I'm considering buying an Audi and I've heard a lot about their legendary quattro all-wheel drive system. But I'm not quite sure how it works. Can someone explain it to me?

The quattro all-wheel drive system on Audi vehicles uses a center differential to distribute power between the front and rear axels, providing superior traction and handling in all types of driving conditions.

The quattro all-wheel drive system uses torque vectoring to distribute power between the left and right wheels on the same axel, allowing for precise and dynamic handling in corners.
