- A CD-ROM (compact-disc read-only memory),
- is a computer storage device developed from
- the technology of the audio compact disc. It
- consists of a plastic-coated metal disc, on
- which binary digital information is etched in
- the form of microscopic pits. This can then
- be read optically by passing a light beam
- over the disc. CD-ROMs typically hold about
- 650 megabytes of data, and are used in
- distributing large amounts of text and
- graphics, such as encyclopedias, catalogues,
- and technical manuals.
