What is the difference between Quattro and All-Wheel-Drive in Audi vehicles?

I've often heard these terms being used interchangeably, but are they actually the same thing? Can I expect the same performance from both systems?

Quattro is actually a specific trademarked brand of all-wheel-drive system used in Audi vehicles. It utilizes a Torsen center differential to distribute power between the front and rear axles, providing superior handling and traction. Other AWD systems may vary in design and performance.
