The three things to have a good exposure!
What is Shutter Speed?
Shutter Speed is the nominal time for which a shutter is open at a given setting.
The longer the shutter speed, the more movement blur is captured, therefore if you wanted to photograph someone running but wanted to see the movement, you would use a slower shutter speed but not an extremely slow shutter speed as then you wouldn't be able to see what it is that the person is doing because they would have moved before you took the picture.
The shorter the shutter speed, the more clearer the freeze action. This means that if you wanted to capture the same runner, but wanted a sharp image with detail and precision, you would need a shorter shutter speed as you would want the camera to capture the image faster.

What is Aperture?
Aperture is a space that light passes through in an optical or photographic instrument, such as the variable opening through which light enters a camera.
The wider the aperture, the more light that enters the camera. On a dark and gloomy day, it would be ideal to use a wider aperture to photograph your subject so that more light can enter the camera, as there is not much light o begin with.
The narrower the aperture, the less light that enters the camera. On a bright and sunny day, a smaller aperture would be preferable so as not to allow too much light into the camera, as there is already plenty of it around.

What is ISO?
ISO is the numerical exposure index of a photographic film used to indicate the light sensitivity of the film's emulsion. Changing the ISO changes the cameras sensitivity to light.
The lower the ISO number the less sensitive the camera is to light and the finer the grains captured. In an extremely well-lit room, you would use a lower ISO number, so that the light sensitivity of the camera is lower, to equalize the excess light that is present within the room.
The higher the ISO number, the more sensitive the camera is to light, however, the noisier shots you will get. In a drama studio, or a spotlight lit setting, you would use a higher ISO number, so that the light sensitivity of the camera is higher, to make up for the lack of lighting within the room.
