What Is Quattro and How Does It Work?

I've heard that all Audi vehicles come equipped with Quattro technology, but I'm not sure what it is or how it actually works. Can someone explain it to me in simple terms?

Quattro is Audi's all-wheel drive system that provides power to all four wheels of the vehicle, giving you better traction and control on the road. It uses a center differential to distribute power between the front and rear axles, and can also redirect power to individual wheels as needed.
