Which one of the following pairs least matches in respect of a computer?

A1 Giga Byte : (1024) cubed bytes

BCRT : Cathode Ray Tube

CROM : Rapid Online Memory ✓ Correct

DCPU : Central Processing Unit

Correct answer: (C) ROM : Rapid Online Memory

Explanation

ROM actually stands for Read Only Memory, not Rapid Online Memory, so this pairing is the mismatch.

One gigabyte does equal 1024 cubed bytes, which is a correct pairing.

CRT correctly expands to Cathode Ray Tube.

CPU correctly expands to Central Processing Unit.

ROM holds permanent instructions that remain even when power is switched off.
