Exposure Triangle
The use of three camera settings, which are aperture, ISO and shutter speed.
Shutter Speed
The amount of time the shutter is open during movement. It measures in seconds or fractions of a second. To freeze motion use the fast shutter speed, while to blur motion use the slow shutter speed.
To take picture of a bird, use a fast shutter speed for motion. To write with light, use a slow shutter speed to show the image of light.

Aperture
The depth of field (wide,shallow), which measured in f-stops. You use large aperture for shallow depth of field, when you use small aperture for wide depth of field.
For a picture of a ultrasound, you use shallow aperture to show baby and to blur the background. To take picture of mountain, use the wide aperture to show the whole mountain.
Aperture as Fast As Possible
ISO
The level of sensitivity of your camera to available light. The lower the ISO are used for sunny days. While higher the ISO are used for dark days. The higher the ISO the more noise in the background.
In a gym with moving athletes, you use the high ISO to get more sensitive to the low light.
