A shutter controls the amount of light that is admitted over a certain time.
A diaphragm stops the passage of light through the aperture.

The shutter block all light from the film and opens for a controlled period of time. The diaphragm can go from partially to completely open and determines how much of the lens (the aperture) is used.

I think it is easier to understand if you see a picture.
