What does the anti-lock braking system (ABS) do and how does it work in Audi A2?

I am looking to understand the function and mechanism of the ABS in Audi A2, as well as how it differs from traditional braking systems.

The anti-lock braking system, also known as ABS, is designed to prevent the wheels from locking up during an emergency stop. It works by monitoring the speed of each wheel and adjusting the brake pressure to maintain control of the vehicle. In an Audi A2, the ABS is equipped with sensors that constantly measure wheel speed and are connected to a control unit that operates the brake pressure.
