Etymology
The term CD-ROM is a modern technological compound, formed in the late 20th century from two established English acronyms. "CD" stands for "Compact Disc," a digital optical disc data storage format, while "ROM" stands for "Read-Only Memory," a type of non-volatile memory used in computers where data is pre-written and not normally modified. The hyphen serves to link these two acronyms into a single lexical unit. The word's logic is entirely descriptive, specifying a compact disc that contains data in a permanent, read-only format, distinguishing it from audio CDs or recordable discs.
