Computer graphics is the field of visual computing, where one utilizes computers both to generate visual images synthetically and to integrate or alter visual and spatial information sampled from the real world.
The term digital art is usually reserved for art that has been non-trivially modifed by the computer; text data and raw audio and video recordings are not usually considered digital art, in themselves but can be part of a larger project, since the computer is merely the storage medium or tool which is used to create the work.
