CD-RW stands for what?

• A. Compact Disc-Rewritable
• B. Compact Disc Read-only Memory
• C. Compact Disc Random Access
• D. Compact Disk Rewritable

Answer: (A)

CD-RW refers to Compact Disc-Rewritable. This type of optical media can be written, erased, and rewritten multiple times, thanks to a phase-change material inside the disc that allows data to be overwritten. It’s different from CD-R, which is write-once, and CD-ROM, which is read-only. The slight spelling variation between Disc and Disk isn’t changing the meaning; the standard term used for this format is Compact Disc-Rewritable.
