What is the difference between Quattro and S Tronic transmissions in Audi vehicles?

I've heard about these two options for transmissions in Audi cars, but I'm not sure what sets them apart. Can someone explain the technical differences and what to consider when choosing between them?

Quattro is Audi's all-wheel drive system, which distributes power to all four wheels for optimal traction and handling. S Tronic is Audi's dual-clutch automatic transmission, providing lightning-quick gear shifts for a sportier driving experience. When choosing between the two, consider your driving needs and preferences. If you live in an area with rough terrain or harsh weather conditions, Quattro may be a better choice, while S Tronic is great for those looking for a more dynamic driving experience.
