What is the difference between Audi's Quattro and All-Wheel Drive technology?

I am considering purchasing an Audi, but I am unsure of the difference between their Quattro and All-Wheel Drive technology. Can someone explain the technical details of how each system works and which one would be more suitable for my driving needs?

Quattro is Audi's proprietary all-wheel-drive system that utilizes a center differential to distribute power between the front and rear axles, providing optimal traction and performance in various weather conditions. All-Wheel Drive is a generic term for any system that sends power to all four wheels, but the specific technology and effectiveness can vary greatly among manufacturers.
