CD-ROM

CD-ROM
CD-ROM (an abbreviation of "Compact Disc Read-Only Memory") is a compact disc that contains data accessible by a computer with a CD-ROM drive. While the compact disc format was originally designed for music storage and playback, the format was later adapted to hold any form of binary data. CD-ROMs are popularly used to distribute computer software, including games and multimedia applications, though any data can be stored (though only up to the capacity limit of a disc). Some CDs hold both computer data and audio with the latter capable of being played on a CD player, whilst data (such as software or digital video) is only usable on a computer. These are called Enhanced CDs.

Although many people use lowercase letters in this acronym, the proper presentation is in all capital letters with a hyphen between CD and ROM (CD-ROM).
