Freebase(0.00 / 0 votes)Rate this definition: CD-ROM. A CD-ROM is a pre-pressed compact disc which contains data. The name is an acronym which stands for Compact Disc Read-only Memory. Computers can read CD-ROMs, but cannot write on them.
Some CDs, called enhanced CDs, hold both computer data and audio with the latter capable of being played on a CD player, while data (such as software or digital video) is only usable on a computer (such as ISO 9660 format PC CD-ROMs). The Yellow Book is the technical standard that defines the format of CD-ROMs. One of a set of color-bound books that contain the technical specifications for all CD formats, the Yellow Book, created by Sony and Philips in 1988, was the first extension of Compact Disc Digital Audio.
