Which statement about RAM is true?

Which statement about RAM is true?

• A. It is non-volatile and stores long-term data
• B. It is volatile and data is lost when power is off
• C. It cannot be read by the CPU
• D. It is used to store permanent programs

Answer: (B)

RAM is fast, temporary workspace that the CPU uses to hold data and instructions for running programs. It is volatile, meaning its contents disappear when power is removed. That’s why unsaved work or intermediate data in active programs is lost after shutting down or a power outage. RAM is not for long-term storage, and the CPU can read from and write to it directly. Permanent programs and data are kept in non-volatile storage like hard drives or SSDs, which retain information without power. So the true statement is that RAM is volatile and data is lost when power is off.
