What is a DVD?


A DVD is simply an optical data storage medium. The word was originally an acronym for "digital video disc" and "digital versatile disc," but today DVD is a word itself and officially does not stand for anything. It is used to store audio, video, and computer data.

DVD's are classified into physical and application formats. Before learning about how DVD's can be applied you need to understand the various physical formats of DVD media available. The discs may look the same but they have different uses and do vary.
