Exposure
Exposure is the amount of time the shutter is open for and therefore it is the amount of light that is allowed to strike a light-sensitive material. The amount of exposure can be adjusted by setting the camera to manual and holding it down to the desired length of time. More exposure is used to make brighter pictures on still objects and less exposure is used to capture fast moving objects. The aperture is a device on a camera that controls the amount of light that is allowed into the camera and it is controlled with f-stop. Brightness is reduced as light passes through the aperture. The aperture can be set to many different settings the narrower it is the more focused the background is and vice versa.

You don't keep the shutter open longer by holding the button down longer ... the camera precisely controls it with a setting.
Keep researching ...
Some ideas for further research.
What are sample shutter settings?
What are some sample Aperture sized?
How is an F-Stop calculated?
What is a "Stop" (for shutter and for aperture).
What is the relationship between Shutter and Aperture?
What camera settings allow you to set the aperture and shutter.
