In sleep mode, which component's contents are preserved?

• A. RAM contents
• B. ROM contents
• C. Hard drive contents
• D. Cache contents

Answer: (A)

In sleep mode the system uses a suspend-to-RAM state, keeping the contents of RAM powered so the session can resume quickly. RAM is volatile, meaning it loses data if power is removed, but as long as it stays powered in sleep, all your open programs and documents stay exactly as they were. ROM already stores data non-volatile and isn’t needed to be kept active for a quick resume. The hard drive also stores data non-volatile and isn’t kept “alive” in sleep for the purpose of preserving the current session. Cache is a small, fast memory near the CPU that’s typically volatile and not guaranteed to retain its contents when power is saved, so it isn’t the component relied on to preserve state in sleep mode.
