Which of the following correctly states the full form of CD and the technology used to store data on it?
Compact Disc, Optical Storage
The abbreviation CD stands for Compact Disc, not Compact Drive; it is a flat, circular disc, not a drive mechanism.
Data on a CD is stored optically. During writing, information is encoded as a spiral track of microscopic pits and lands (flat areas) on the disc surface.
During reading, a laser beam is focused on this track. Pits and lands reflect the laser differently, and the drive converts these variations in reflected light back into binary data.
Because it relies on light rather than magnetised regions, the storage is optical, unlike a hard disk or tape which uses magnetic storage.
Hence, the answer is Compact Disc, Optical Storage.
