1) It controls how long the film or sensor is exposed to light for, the longer the time it is open, the darker the image (over exposure vs under exposure)

2) Don't really get this question but it is in fractions of a second as in 1/60 (one over 60, or a 60th)

3) Bulb!. This is where the shutter stays open for an infinite amount of time!. You press the shutter again to close it!. Good for star trails, etc!.

4) Faster the speed, the wider the aperture, the slower the speed, the narrower the aperture!.
