Ya it can be kinda confusing. Here as a down and dirty table to help break it down.

Shutter SpeedShutter Speed – the length of time a camera shutter is open to expose light into the camera sensor. Shutter speeds are typically measured in fractions of a second, when they are under a second.Dolor
ApertureAperture – a hole within a lens, through which light travels into the camera body. The larger the hole, the more light passes to the camera sensor. Aperture also controls the depth of field, which is the portion of a scene that appears to be sharp. Aperture is also referred to as F-Stop. 
ISOISO – a way to brighten your photos if you can’t use a longer shutter speed or a wider aperture. Examples of ISO: 100, 200, 400, 800, 1600.
