• Primary unit of color on a computer monitor or in an electronic image.^[1]

• The basic building block of all images -- a simple dot. In bitonal images, it is merely a black or white dot (see "Bitonal" definition above). In grey scale images, dots will have between 1-to-256 possible values of grey (for an 8-bit grey scale image).^[2]

• A dot. One step/addressable position in the total TV or CRT presentation. The minimum VGA display has 307,200 pixels (640 by 480).^[3]

• A picture element. A pixel is the smallest dot on the screen of a computer display. Screen resolution is usually measured in the number of pixels horizontally and vertically that the screen can display (ranging from 640 × 480 to 1280 × 1024, or higher). Generally, the higher the resolution, that is, the more pixels in the image, the clearer the image will appear.
