What Does the 'Quattro' System in Audi A6 Actually Do?

I'm trying to understand what exactly the 'Quattro' system in the Audi A6 is and what it does. I've heard it helps with traction, but I'm not entirely sure how. Can someone explain this to me?

The 'Quattro' system in an Audi A6 is an all-wheel drive system that distributes power to all four wheels, which helps with traction and improves the overall handling of the car. It's especially useful in wet or slippery conditions, giving you more control and stability while driving.
