If you're unfamiliar with electronics, they can be viewed as an electrical one-way valve.

Seconded - 4 of them in one circuit next to each other makes a full bridge rectifier to turn AC into pulsed DC. Commonly found in electronics that have a wall plug but have simple electronics - you'll see power enter, go through these, then through a transformer (or through a transformer then through these diodes), then through some capacitors to smooth out the power and make a usable power source for small circuits.

Commonly found in:  Practically everything :D  Older tvs, practically all DC transformers (not newer smps transformers - just older big wall warts), alarm clocks...you name it.

You can deduce domething of what they do by looking at where they're connected before taking them off the board.
