What is CD-ROM?

An acronym for Compact Disk Read-Only Memory. A CD-ROM can store large amounts of information (~700 MB); generally used to distribute software or multi-media for use on computers with CD-ROM drives. The data written on CD-ROM cannot be altered or erased by a user. CD-ROMs are just like normal audio CDs, but they are formatted in such a way that they can store many types of data.
