Which abbreviation represents Compact Disc Rewritable?

• A. CD
• B. CD-RW
• C. CD-ROM
• D. CAN

Answer: (B)

Rewritable means you can erase and write data on the disc multiple times. The abbreviation that indicates this capability is CD-RW, where RW stands for ReWritable. This distinguishes it from a standard CD (a general term), a CD-ROM (read-only memory, data can’t be written after manufacture), and CD-R (recordable but not erasable). CAN isn’t related to optical discs. CD-RW discs use a material that can switch states with a laser, allowing data to be erased and rewritten as needed.
