MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -In digital imaging, a pixel (abbreviated px), pel, or picture element is the smallest addressable element in a raster image, or the smallest point in an all points addressable display device. In most digital display devices, pixels are the smallest element that can be manipulated through software.
