67. Which of the following devices have a limitation that we can only read it but can not erase or modify it?
Verified Answer
A. Tape drive
B. Hard disk
C. Compact disk
D. Floppy disk
E. None of these
Explanation:
A 'Compact disk', specifically a CD-ROM (Read-Only Memory), is designed to be read-only and cannot be erased or modified by the user. Tape drives, hard disks, and floppy disks are all read/write devices. Thus, 'Compact disk' (CD-ROM) is the correct answer.
