Compact disc

[Dave Paprocki]

A CD.
A small [optical] disk on which data such as music, text, or graphic images is digitally [encoded].
In the 20th century, the spelling compact disc was preferred by persons in the UK, while [compact disk] was preferred by persons in the USA. Recently, the computer industry has come to use disk, while the music industry uses disc.
Thus, a compact disc will generally contain music.

[Zipporah Schumaker]

If [you dont know] what a [compact disc] is, you are [fuckin] stupid!
