Shutting Down the Computer

1. Sleep: 🌙
   • This is like when you take a quick nap. The computer stops working for a little while but wakes up quickly when you need it.
   • Example: Pressing the power button once.
2. Hibernate: 🌟
   • Hibernate is like when you put your computer to bed for the night. It saves all your work and turns off completely, but it takes longer to wake up.
   • Example: Closing the lid of a laptop.

Distinguishing Between Shutdown Methods

• Restart: 🔄
  • Restarting is like giving your computer a fresh start. It turns off and then turns back on again.
  • Example: Clicking on the restart button in the Start menu.
• Shutdown: ⛔
  • Shutting down is like saying goodbye to your computer for now. It turns off completely.
  • Example: Clicking on the shutdown button in the Start menu or pressing and holding the power button until the computer turns off.
