ISO, Aperture, and Shutter Speed
The Exposure Triangle
Smaller ISO numbers indicate a lower sensitivity to light and requires more light for successful exposure, larger ISO indicates a higher sensitivity to light and requires less light for exposure
Higher ISO (400,800,1600,3200) are more sensitive to light
ISO 800,1600, 3200 will show a lot of noise/grain in your photos. So you want to make a choice on whether you want to capture that photo and sacrifice quality or if you have a tripod available you can shoot on ISO 200 and use a slower shutter speed with getting the grain.
