Определение и Значение "pixel"

What is a "pixel"?

A pixel, short for "picture element," is the smallest unit of a digital image. Each pixel represents a single point of color and contributes to the overall image when combined with thousands or millions of other pixels. The resolution of an image, which affects its clarity and detail, is determined by the number of pixels it contains. Higher resolution images have more pixels, allowing for finer detail and clearer pictures.
