Someone will probably answer before me and answer better. Anyway,
>>185509 Film speed, which is measured in ISO, is more or less how sensitive the film is to light. "Faster" films of a higher iso have more sensitivity while lower iso films have a lower sensitivity. The disadvantage to using high speed films, however, is that grain is more obvious at higher speeds. As a beginner, I used 400 iso. I think it's a good balance of speed and grain.
Aperture the width of the hole that lets the light on the film. A larger aperture lets more light in, and vice versa. Larger apertures require faster shutter speeds than small apertures because the larger aperture lets in more light. Aperture is shown in f stops. For some reason, the lower the f number, the wider the aperture. f/1.4 is very wide, while f/28 is very small.
Aperture also affects depth of field. Depth of field is how much of the photograph is in focus. A larger aperture, like f/1.4 or f/2 will commonly have the subject in sharp focus with a blurry background. This is useful for portraits. On the contrary, at f/28, most of (if not all) of the scene will be in focus, as in landscape photography.
I'm not a very good photographer, these are just general hints.
