What does DVD-R stand for?

• A. Digital Video Disc-Recordable
• B. Digital Video Disc-Rewritable
• C. Digital Video Disc
• D. Digital Video Disc-Data

Answer: (A)

Understanding what the R stands for on DVD-R helps you see why this description is correct. The R indicates that the disc is Recordable, meaning you can write data to it once, and you can’t erase or rewrite later. This is the defining feature that distinguishes DVD-R from other types like rewritable discs (which can be erased and reused) or from a plain pre-recorded DVD. So Digital Video Disc-Recordable matches the concept of a write-once optical disc. Note that the official term for DVD is Digital Versatile Disc, but the important point is the write-once capability implied by the Recordable designation.
