Which of the following statements about computer memories is correct?

AAn HDD may experience a 'head crash' ✓ Correct

BSSDs are also known as volatile memory

CHDDs do not have any moving parts

DComputers usually have more primary memory than secondary memory

Correct answer: (A) An HDD may experience a 'head crash'

Explanation

A hard disk drive can suffer a head crash when its read-write head touches the spinning platter and damages the surface.

This risk exists because an HDD stores data on magnetic platters that spin at high speed.

The claim that SSDs are volatile is wrong, since flash-based SSDs keep data without power.

The claim that HDDs have no moving parts is wrong, as they rely on spinning platters and moving heads.

The claim that computers hold more primary than secondary memory is wrong, since secondary storage is usually far larger.

Primary memory like RAM is fast but small, while secondary storage is large and permanent.
