A pixel, short for “picture element,” is the smallest discrete component of a digital image. Pixels are arranged in a grid, and each pixel contains color and intensity information. The number and quality of pixels determine an image's resolution, with higher-resolution images having more pixels, resulting in sharper and more detailed visuals. Pixels play a crucial role in all digital imaging processes, from photography and graphic design to display on various devices such as monitors, smartphones, and digital projectors.
