Which among the following statements is incorrect about secondary memory?
 

Show answer & explanation

Correct answer: D

Explanation

The correct answer is Option 4 i.e. It is a volatile memory.

  • The incorrect statement is: "It is a volatile memory."
  • Secondary memory is non-volatile memory, not volatile.
  • Volatile memory, like RAM (Random Access Memory), loses its data when the power is switched off, while secondary memory, such as hard drives or SSDs (Solid State Drives), retains data even when the power is switched off.
  • Secondary memory is used for long-term storage of data and is non-volatile in nature, making it suitable for storing data that needs to be retained even when the computer is powered down
