Quizplus · Accepted Answer

CDs and DVDs are optical storage devices, meaning they use light to read and write data onto the disc's surface. Option B, binary, refers to the system of representing data using only two values (0 and 1), and is not specific to CDs and DVDs. Option C, legacy, means something that is outdated or no longer in use, which does not apply to CDs and DVDs as they are still used today. Option D, encoded, could be relevant as CDs and DVDs use specific encoding methods to store data, but it is not specific enough to be the best answer.
