Definition

single photograph in a sequence representing motion, or movement, on film; in a network, a unit of data; in word processing or desktop publishing, a marked-out area on a page that can contain text or graphics. What appears to be motion on a cinema or TV screen is actually a rapid sequence of single shots. Because of limitations in the human eye – known as the Phi phenomenon – those individual shots, if played in sequence at a rate of 24 to 30 frames per second, make the motion thus captured appear continuous.
