ISO settings are about the light sensitivity of the digital chip or film. The higher the ISO the more sensitive the chip becomes, meaning that you can take a photograph when there is less light. However, at higher ISO settings an image is more likely to be affected by digital noise or grain (this can also be a desired effect).
An ISO of 200 is the average daylight setting.
ISO can be also used on cameras to make the photo have noise in it or not the higher the value of the ISO the more noise.
