The aperture, aka the f-stop, is the size of the opening in the diaphragm inside the lens. It is an inverse scale, which means the smaller the number - f1.7, f2 - the larger the opening. The bigger the number - f11, f16 - the smaller the opening.
The size of the f-stop determines how much light is admitted by the lens. A wider opening allows a faster shutter speed; a smaller opening requires a slower shutter speed.
