Closed = Bigger and better DoP (Depth of Field) < Light
Open = Less DoP > Light
The Aperture scale is a constituted by the multiples of two scales.
A. 2.4/2.6/2.8
B. 3.5/3.7
A. 4
B. 6.4/7.2
A. 8
B. 12
A. 16
AB. 22
B. 24
P.S:. There are slight changes from camera to camera, as there are from type-1 lens to type-2 lens (where type-1 and type-2 indicate or apply to any different type of lenses, regardless of what their type is.), which is why some of the stops of the scale can vary (i.e:. 2.4/2.6). Some cameras/lenses will have 2.4, some other will have 2.6, and so on. Scale A is multiples of 2, whereas scale B is multiples of 3. There non-rounded numbers, such as 2.4 or 6.4 exists because of the imperfection between the several apertures --not because the apertures were/are done imperfectly, but because in such a small measurement, it is hard to concise so much light-information that stays true and relevant to reality, through such a small aperture. It's a bit more complex than this, and I haven't got much time to explain the rest.
P.S.S:. Just realised this has already been answered to. Oh well.
