Which of the following statements are true about volatile memory?Each correct answer represents a complete solution. Choose all that apply.

Question

Options

• ARead only memory (ROM) is an example of volatile memory.
• BThe content is stored permanently and even the power supply is switched off.
• CA volatile storage device is faster in reading and writing data.
• DIt is computer memory that requires power to maintain the stored information.

• B
  5% (1)
• C
  95% (21)

Explanation

Volatile memory (primarily RAM) requires continuous power to retain data (D), and because it uses electrical charges rather than mechanical or persistent storage mechanisms, it offers significantly faster read/write speeds compared to non-volatile alternatives like hard drives or flash storage (C).

Why the distractors are wrong:

• A is incorrect because ROM is non-volatile - it retains data without power, which is the opposite of volatile behavior.
• B describes non-volatile memory (e.g., flash drives, ROM), where data persists after power loss; volatile memory loses all stored content when powered off.

Memory tip: Think of "volatile" like a volatile person - unpredictable and temporary. RAM is volatile: fast and reactive, but loses everything the moment the power (relationship) ends. ROM and SSDs are the stable, long-term storage - they remember even after the power is gone.
