The same article explains f/stops.
Smaller the f/stop #, the more light gets through.

F can be variable as in the maximum aperture on a zoom lens will change from say 70mm f 4.5 to the pther end will be 200mm f 5.6. apertures on a zoom that are constant- say 80-200mm f 2.8 are usually more expensive "pro" level lenses for that particular manufacturer
