Which of the following devices has a limitation that we can only read information from it but cannot erase or modify it?

Q. Which of the following devices has a limitation that we can only read information from it but cannot erase or modify it? 

(A) Floppy disk
(C) Tape drive
(B) Hard disk
(D) CD-ROM

Answer: CD-ROM

Read-only memory (ROM) is a type of non-volatile memory used in computers and other electronic devices. Data stored in ROM can only be modified slowly, with difficulty, or not at all, so it is mainly used to store firmware (software that is closely tied to specific hardware, and unlikely to need frequent updates) or application software in plug-in cartridges.

A CD-ROM is a pre-pressed optical compact disc which contains data. The name is an acronym which stands for "Compact Disc Read-Only Memory". Computers can read CD-ROMs, but cannot write to CD-ROMs, which are not writable or erasable.
