Exposure Triangle

Shutter Speed
Shutter speed is the amount of time the shutter stays open during exposure. A faster shutter is used more often for motion pictures, and there is little to no blur. A slower speed is used for stationary pictures, or when you want a blur to your pictures.
Aperture
Aperture is the size of the opening of the lens. It is measured in f-stops. A smaller f-stop, like 1.4, has a larger opening and gets smaller, making it useful for taking pictures of birds and things like that. A larger f-stop, like f-8, has a smaller opening and gets larger, making it useful for landscape photos.

ISO
ISO is how sensitive your camera is to light. A low ISO is used on sunny days or when there is a lot of light. A higher ISO is used when there is less light. When upping your ISO, be aware that there will be more noise in your shot.
White Balance
White balance is used to make sure the colors in your shot as accurate as possible.
