CD-ROM
|
Compact Disc-Read Only Memory CD-ROM can refer to either the equipment that uses a CD or it can refer to the CD itself. Typically we might call a CD with music on it a CD and a CD with data, games, etc on it a CD-ROM. All in all the most important thing to learn is that that thing on your computer with the sliding tray and a hole in it is not a coffee holder.
