CD-ROM

[Mark Zuckerberg]

Stands for Compact Disc Read-Only Memory. A CD-ROM is a CD that can be read by a computer with an optical drive. The ROM part of the term means the data on the disc is read-only, or cannot be altered or erased. Because of this feature and their large capacity, CD-ROMs are a great media format for retail software. The first CD-ROMs could hold about 600 MB of data, but now they can hold up to 700 MB. CD-ROMs share the same technology as audio CDs, but they are formatted differently, allowing them to store many types of data.
