F-Number: The resulting number when the focal length of a lens is divided by the diameter of the aperture. The sequence of numbers represent of various openings between the maximum and minimum settings. F-numbers are actually fractions, so the large numbers allow less light to pass.
F-Stop: The marking on the ring or dial that controls the diaphtagn. It is an indication of the amount of light passing through the aperture. A small f-stop, such as f/16 admits little light. The F denotes fraction so the larger the denominator the smaller the opening.
Shutter: A mechanically or electronically controlled device that regulates the length of time light is allowed into the camera for film exposure.
ISO: A system of rating the emulsion speed of film.
Aperture: The opening in the camera lens that regulates the amount of light reaching the film. The aperture may be fixed in size or adjusted by a diaphragm.

Below is a YouTube video on how to capture waterfalls in two different ways. Although it is directed at digital photography, it applies to film. Pay attention to ISO and shutter speed when watching.
Shutter Speed (click to learn more)
This picture has the shutter speeds circled. If your camera has a light meter in it, it will suggest a setting. Notice the small white box. This is where your ISO speed is set. You will find this on the box and on your roll of film. Perhaps it is 100 or 400. Click here for a better understanding on ISO numbers.

Focal Plane Shutter: A camera's shutter system consisting of sliding curtains. It is positioned slightly in front of the focal plane.
Focal Plane: The plane in the camera where the film's surface is positioned.
Focal length: The distance between the optical center of a lens and the focal plane when the lens is focused at infinity. The greater the focal length, the smaller the angle of view.
