What is the difference between Quattro and all-wheel drive in Audi A4?

I've heard people mention Quattro and all-wheel drive when talking about Audi A4. I'm confused about what the difference is between the two and which one would be better for my driving needs. Can someone explain the technical aspects and specific benefits of each option?

Quattro is Audi's patented all-wheel drive system, designed to distribute power evenly between all four wheels for enhanced traction and stability. It's ideal for driving in slippery conditions or on rough terrain. On the other hand, all-wheel drive refers to any drivetrain that provides power to all four wheels, but it may not have the same advanced technology and performance as Quattro.
