Which type of information is lost when power is lost?

• A. Non-volatile Information
• B. Cached Information
• C. Volatile Information
• D. Persistent Information

Answer: (C)

This question hinges on the difference between volatile and non-volatile memory. Volatile information is stored in memory that requires power to maintain its contents, such as RAM and CPU caches. When the power is removed, this data is lost, which is why it’s described as volatile. In contrast, non-volatile or persistent information is stored on devices like hard drives, SSDs, or flash memory and remains even after power is lost. While cached information is typically in volatile memory as well, the term that best matches the concept of data disappearing when power is cut is volatile information.
