Aperture in simpler terms is the hole within the lens of a camera which light travels through into the body of the camera. This is presented as f/stops and are generally written as numbers such as 16, 11, 8, 5.6, 4, 2.8, 2 and 1.4. The higher f/stops give less exposure because they represent smaller apertures whereas lower f/stops give more exposure because they mean the complete opposite, this may sound counterintuitive but will make sense the once you start taking different pictures playing with the aperture.
These charts will help you distinguish what a higher or lower aperture determines:
Depth of Field and how its affected by Aperture:
Depth of Field is the area of the image of which is sharp, aperture is the main factor in determining how much of the scene appears as sharp and how much is unfocused and blurred. More depth of field makes means the aperture (f/stop) is larger and also means more of the scene is focused on, for example, an aperture of f/22 will mean that the majority of your image taken is sharp and completely visible.
Now, of course when the aperture is larger there is more depth of field but when the aperture becomes smaller, less depth of field is present. An easy way of representating this would be using this image shown to us on a powerpoint. It shows how aperture effects the depth of field in a visual form.
