CD-ROM, compact disc read-only memory(noun)
a compact disk that is used with a computer (rather than with an audio system); a large amount of digital information can be stored and accessed but it cannot be altered by the user
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. CD-ROMs are popularly used to distribute computer software, including video games and multimedia applications, though any data can be stored. Some CDs, called enhanced CDs, hold both computer data and audio with the latter capable of being played on a CD player, while data is only usable on a computer. 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. It adapted the format to hold any form of data.
U.S. National Library of Medicine
