Typical acronym of reuseable optical storage will be............
Verified Answer
A. (a) CD
B. (b) CD-RW
C. (c) DVD
D. (d) RPM
E. (e) None of these
Explanation:
Option (b) CD-RW (Compact Disc-ReWritable) is the correct answer as it denotes a type of optical storage that allows data to be written, erased, and rewritten multiple times, making it reusable. Option (a) CD (Compact Disc) is typically a read-only medium. Option (c) DVD (Digital Versatile Disc) is also primarily read-only or write-once for consumer versions, not inherently reusable in the same manner as CD-RW. Option (d) RPM (Revolutions Per Minute) is a unit of rotational speed, commonly used for hard drives, not a type of storage medium itself. Therefore, (e) None of these is incorrect.
