CD stands for Compact Disc.

Important PointsCompact Disc:

  • Compact disc (CD), a molded plastic disc containing digital data that is scanned by a laser beam for the reproduction of recorded sound and other information.
  • Since its commercial introduction in 1982, the audio CD has almost completely replaced the phonograph disc (or record) for high-fidelity recorded music.
  • The CD's storage capacity is only about 700 MB, which is just about 74 minutes of audio.

Hence, CD is an abbreviation for “compact disc,” and its compact in more than one way.
