Question

what is a pixel , explane briefly ?????

Answer 1

Answer:

In digital imaging, a pixel, pel, or picture element is a physical point in a raster image, or the smallest addressable element in an all points addressable display device; so it is the smallest controllable element of a picture represented on the screen.

• The pixel is the basic unit of programmable color on a computer display or in a computer image. Think of it as a logical - rather than a physical unit. The physical size of a pixel depends on how you've set the resolution for the display screen.

• If you've set the display to its maximum resolution, the physical size of a pixel will equal the physical size of the dot pitch of the display. If, however, you've set the resolution to something less than the maximum resolution, a pixel will be larger than the physical size of the screen's dot.
