F22 - All the lenses I have for my 35mm camera have an F22 setting, this lets the least amount of light through the lens.
most home computers use ATX (Biggest), micro-ATX or mini-ATX (Smallest)
These are tab stops. In Microsoft Word you can create a tab stop by clicking and dragging on the horizontal ruler, where they appear as flipped-over black L or T marks. If there are faint marks below the ruler at 1-inch intervals, these are the default tab stops.

Can a sender and receiver use asynchronous transmission and agree not to use any stop elements?
The way to stop your laptop from charging is to unplug the charger from the computer. When the battery starts to get low on power plug it back in.
lens opening; lens diaphragm some might suggest F-Stop
An aperture is an opening in the centre of your lens through which light passes. The amount of light, which passes through an aperture, is indicated by f/stops or f/numbers. The lower the f/stop the more light that passes through the aperture. Opening up one full f/stop doubles the amount of light entering the camera. F/4 admits twice the light of f5.6. www.goldprints.com
The main function of a camera lens is to collect light. The aperture of a lens is the diameter of the lens opening and is usually controlled by an iris. The larger the diameter of the aperture, the more light reaches the film / image sensor.Aperture is expressed as F-stop, e.g. F2.8 or f/2.8. The smaller the F-stop number (or f/value), the larger the lens opening (aperture).
It is a measure of the size of the opening in the lens for the light to pass through. The smaller the f-stop the larger the lens opening, and large f numbers relate to small openings or apertures in the lens.
Aperture and shutter speed control the amount of light that passes from the lens to the film or digital sensor of a camera. Aperture is the size of the opening within the lens. The lower the f-stop number (1.4 for example) the larger the opening and the more light is passed through. Shutter speed is closely related. It is the amount of time that the lens is open. The combination of the size of the opening in the lens and the amount of time that the lens is open determine the exposure.
stop is a chemical used in the process of making prints or developing film. It stops the developer from over-developing the print or film. It also refers to the f-number, or f-stop, which is the aperture size (diaphragm opening) used by the lens at the moment of exposure.
In general, aperture does not start at 2.8. The aperture of a particular lens, however, can start at 2.8 depending on how the lens was built. Some lenses are designed so that the lowest f stop (aperture) is 2.8. Some lenses aperturef-stop may start at 1.4. Or 5.6. It just depends on the lens. So....again, in general, aperture does NOT start at 2.8.

F Stop
The largest camera aperture is f stop 1.4, which lets the most amount of light into the camera.
Depth of field on a camera is controlled by the aperture. The aperture is basically the size of the opening in the lens. A large aperture (or opening) creates a shallower depth of field and a small aperture creates a greater depth of field. Aperture, along with shutter speed, determine how much light goes into the camera. The size of the aperture is indicated by the f/stop number. The numbers usually range from about f/1 to around f/64. The smaller the number is, the larger the aperture is and the shallower the depth of field, meaning less space is in focus.Additional AnswerDepth of field is also affected by the focal length of your camera's lens. For any given aperture, longer focal length lenses (telephoto lenses) have a much narrower depth of field than a standard lens, and shorter focal length lenses (wide-angle lenses) have a much wider depth of field than a standard lens.
Aperture measures the amount of light that enters the camera and exposes the film. Aperture values correspond to the amount of available light and the desired shutter speed. Aperture also controls depth of field.
