Which term means the smallest element of a digital image?

• A. Pixel
• B. File Extension
• C. Expand a folder
• D. Adjacent Files

Answer: (A)

A pixel is the smallest element of a digital image. In a raster image, the picture is built from a grid of tiny squares called pixels, each holding color data (like RGB values). The overall appearance and detail of the image come from the combination of all these colored dots; higher resolution means more pixels and finer detail. The term comes from “picture element,” highlighting that each pixel is the smallest controllable unit that contributes to the image. The other terms don’t relate to image structure: a file extension identifies the file type, expanding a folder is a filesystem action, and adjacent files are simply neighboring files.
