  3. Memory · Memory needs power to remember, while storage keeps files without it.
  4. The photo sat in memory, which forgets without power · Unsaved work lives in memory, and memory forgets when power dies.
  5. Scanner, chip, drive, speaker · The scanner takes in, the chip works, the drive keeps, the speaker sends out.
  6. False · The microphone carries sound into the computer, so it is input.
  7. Pull the power: the stick keeps files, memory forgets, so the jobs differ · The power-loss test splits them: storage keeps, memory forgets.
