What does the Audi A1's Electronic Stability Control system do?

I've been hearing a lot about the Electronic Stability Control (ESC) system in the new Audi A1, but I'm not exactly sure what it does. Can you explain?

The Electronic Stability Control system is an advanced safety feature that helps keep your car stable and on the road in difficult driving conditions. It works by detecting when the car is losing traction or skidding, and automatically applies the brakes to individual wheels to help prevent a loss of control.

The ESC system is vital for maintaining safety on the road, especially in wet or slippery conditions. It essentially acts as an extra set of eyes and helps to keep your car under control, even in emergency situations.
