Explanation:
Detailed explanation-1: -A pixel is represented by a dot or square on a computer monitor display screen. Pixels are the basic building blocks of a digital image or display and are created using geometric coordinates.
Detailed explanation-2: -They are not little squares but dimensionless points where the wave amplitude is measured. From a set of such point-like samples, the complete image (or sound wave, or any other signal) can be fully reconstructed.
Detailed explanation-3: -The full form of the pixel is “Picture Element.” It is also known as “PEL.” Pixel is the smallest element of an image on a computer display, whether they are LCD or CRT monitors. A screen is made up of a matrix of thousands or millions of pixels.
