"A CD-ROM /\u02CCsi\u02D0\u02CCdi\u02D0\u02C8r\u0252m/ is a pre-pressed optical 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 to CD-ROMs which are not writable or erasable.Until the mid-2000s, CD-ROMs were popularly used to distribute software for computers and video game consoles."@en . . .
