Newbie question about PWM

Hello Arduino Fan,

I am wondering in what context one uses PWM for driving output devices. I mean beside the standard LED, what are other uses for PWM

Thanks

Controlling brightness of LEDs.
Controlling motor speed.
Audio output.
Faking a DC level (with added RC filter).

Controlling signal for a servo.
