Photos on computers
Digital images are pictures stored as numerical data rather than physical media like film or paper.
Each image consists of pixels—tiny colored dots arranged in a grid—whose values computers can manipulate, compress, and transmit.
The term covers everything from smartphone photos to medical scans to satellite imagery: The museum digitized its collection of digital images for online viewing.
