46. A CD-ROM disk ........
Verified Answer
A. cannot be erased and rewritten
B. has more storage capacity than a CD-R
C. holds less data than a floppy disk
D. can be written only once
E. none of these
Explanation:
CD-ROM means Read-Only Memory; data is factory-pressed and unalterable. CD-R has similar capacity ($\approx 700 \text{ MB}$) but is write-once. Floppy disks hold less data ($\approx 1.44 \text{ MB}$) than CD-ROMs ($\approx 700 \text{ MB}$). CD-R is write-once, not CD-ROM. Thus, CD-ROMs cannot be erased or rewritten.
