Everything about Pixel
Smallest addressable element of a raster image
In digital imaging, a pixel, pel, or picture element is the smallest addressable element of a raster image. In a display device, dot matrix printer, or ASCII art a pixel is the smallest element whose output can generally be controlled independently. Wikipedia →
