What is a pixel?

A pixel is defined as the smallest image component in a digital image. It serves as the basic unit of programmable color on a computer display or in an image. Each pixel represents a single point in the graphic, contributing to the overall resolution and quality of the digital image. When numerous pixels are combined, they form intricate images, whether displayed on screens or printed on media.

Understanding pixels is essential in fields such as graphic design, photography, and digital media, as it helps professionals analyze image resolution, clarity, and detail. This knowledge is crucial for producing high-quality visuals and effectively communicating a message through design.
