The correct answer is Option 4) It keeps the session active in RAM while using minimal power.

Key Points

  • When a computer is put into Sleep mode, it enters a low-power state.
  • All open documents and applications are kept active in the RAM.
  • The system uses just enough power to maintain the memory state, allowing quick resumption.
  • This is ideal for short breaks as it offers a fast wake-up while saving energy.

Additional Information

  • Hibernate mode, by contrast, saves data to the hard drive and powers off, useful for longer downtimes.
  • Shut down closes all programs and turns off power completely.
  • Sleep mode is sometimes called "Standby" on older systems.
  • Power to peripherals like monitors and hard drives is usually cut in sleep mode to save energy.
