animated GIF - Computer Definition
A moving picture in GIF format, which is made up of a series of frames. When displayed, they provide an animated sequence that cycles over and over without stopping. Although popular on the Web, animated GIFs are larger than single-frame GIFs and take longer to download. Typically used for ad banners, the animation is usually confined to small areas of the image to keep the file size short. Very different than GIF and much more sophisticated, Flash is popular on the Web for instructional sequences as well as animations of all kind. Flash is an interactive format and its vector images take up much less space than GIF's bitmapped images. See GIF, Flash and WebP.
