Question What Exactly does Adjusting the Valves Do?

What does adjusting the valves actually do? i.e., better milage? run smoother? quieter? etc?

I am not too mechanically inclined, but I do love to play with diesel engines. In this case, I will take the car to a mechanic, but what if he does it incorrectly? Will it destroy the engine? What damage can be done to the engine if it is done wrong?

Thank you.
