CD-ROM stands for:

ACompressed Disk Read Only Memory

BCompact Device for Reading out Messages

CCompact Device for Read/Write Over Mobiles

DCompact Disk Read Only Memory ✓ Correct

Correct answer: (D) Compact Disk Read Only Memory

Explanation

CD ROM stands for Compact Disk Read Only Memory, an optical disc whose stored data can be read but not overwritten.

Compressed Disk Read Only Memory misnames the disc as compressed rather than compact.

Compact Device for Reading out Messages is an invented phrase unrelated to the optical disc standard.

Compact Device for Read/Write Over Mobiles wrongly makes it a writable mobile device.

A typical CD ROM holds around 650 to 700 megabytes of data.

The read only nature means users retrieve pre recorded content without changing it.
