Start And Shut Down

A computer is an electronic machine that helps us do many tasks quickly. It takes information from us (input), works on it (processing) and shows the results (output). For Class 2, think of a computer as a helpful friend that reads what you give it and gives back something useful.

Main parts of a computer (simple names and roles):

• Monitor: The screen where we see pictures, text and videos. (Like the computer's eyes.)
• System unit / CPU: The box that contains the computer's brain. It processes information.
• Keyboard: Used to type letters and numbers. (Like the computer's hands.)
• Mouse: A device used to point, click and choose items on the screen.
• Printer: Makes a paper copy of what is on the screen (hard copy).
• Speakers: Let us hear sounds and music from the computer.
• Storage (USB/flash drive): Small devices to save files and pictures so we can use them later.

How a computer works (simple steps):

• Input: We give information using the keyboard, mouse or microphone.
• Processing: The CPU (brain) works on the information.
• Output: The result appears on the monitor or comes out from the printer or speakers.

Starting and shutting down safely:

• To start: Make sure power is on, press the computer's power button and wait until the screen shows the desktop.
• To shut down: Close programs, click the Start/Power menu and choose Shut down. Wait until the screen goes off before switching off the main power.
• Safety tips: Keep food and water away, do not touch cables with wet hands, and always turn the computer off when not in use.

What does “Starting the Computer” mean?
Starting the computer means turning it on and waiting until the screen shows the desktop or welcome screen so you can use programs, play educational games, or do homework.

Simple steps to start a computer:

1. Check power: Make sure the computer, monitor, and speakers are plugged into the power socket and the switch (if any) is ON.
2. Press the monitor power button (if separate).
3. Press the computer (CPU or laptop) power button once. You may hear a beep or see lights and a logo on the screen.
4. Wait quietly while the computer starts — you will see a welcome screen, loading messages, or desktop icons.
5. If there is a login screen, type your name or ask a teacher/parent to help you log in.
6. When the desktop appears, you can open a program or game by double-clicking an icon.

Safety and care while starting:

• Do not pull or tug cables; ask an adult to plug things in.
• Make sure your hands are dry before touching the power button or plugs.
• If nothing happens when you press the power button, tell a teacher or parent — do not try to fix internal parts yourself.

What you might hear or see: A short sound (start-up tone), lights on the computer case, the brand logo, and then the desktop or welcome screen. This is normal.

What is shutting down? Shutting down a computer means turning it off in a safe way so that your work is saved and the computer is not harmed. We do this when we finish using the computer or before moving it.

Why shut down properly? A proper shutdown keeps your files safe, helps the computer rest, and saves electricity. If you switch the power off suddenly, you might lose your work or harm the computer.

Simple steps to shut down (for children):

1. Save your work: click Save in your game or drawing so nothing is lost.
2. Close programs: close the game, browser or any open windows.
3. Open the Start menu (or the power menu).
4. Click the button that says Shut down or Power Off.
5. Wait until the screen goes dark and the lights turn off before you unplug or walk away.

Good to know: If the computer stops working (frozen), ask a teacher or adult before forcing it off. Sometimes we use Restart instead of Shut down if the computer needs to refresh.

Safety tips: do not unplug the computer while it is shutting down, and do not press and hold the power button unless an adult tells you to.

This topic tells children how to use the computer safely when starting and shutting it down. Follow simple rules to protect the computer, keep yourself safe, and save your work.

Do's

• Ask the teacher for permission before turning the computer on or off.
• Keep your hands dry and clean before touching the keyboard, mouse, or plug.
• Sit properly at the desk and keep a safe distance from the screen.
• Check that wires and plugs are not loose or broken. Tell the teacher if you see a problem.
• Save your work before you shut down the computer (for example, save a drawing or file).
• Use the proper shutdown steps on the screen—do not switch off the power suddenly while the computer is working.

Don'ts

• Do not touch plugs, sockets, or wires with wet hands.
• Do not eat or drink near the computer—spills can damage it.
• Do not pull the mouse or keyboard cables roughly.
• Do not press too hard on the screen or try to open the computer cabinet.
• Do not switch off the power while the computer is saving or updating—this can harm the computer and lose work.

How to start a computer safely

• Make sure teacher says it is okay.
• Check cables are neatly placed and not in the way.
• Turn on the monitor and then the computer (follow your classroom order).
• Wait for the desktop or log-in screen to appear before you begin.

How to shut down a computer safely

• Save your work (drawings, documents).
• Close any open programs or files.
• Use the on-screen Shutdown or Turn Off command. Wait until the screen goes dark and the computer stops making noise.
• Only then can the teacher unplug or switch off the power if needed.

Emergency rule

• If you see sparks, smoke, or smell something burning, move back, tell the teacher, and do not touch the computer or cables.

Class Activities and Questions help young learners practise how to start and shut down a computer safely. Activities are simple, hands-on tasks or games that teach the correct order of steps, safety rules, and good habits (like saving work). Questions check understanding and help the teacher find who needs more practice.

Typical classroom activities include demonstrations by the teacher, guided practice where each child follows the steps, drawing or sequencing tasks, role-play, and short quizzes. Emphasis is on: (1) pressing the correct power button, (2) waiting for the screen to be ready, (3) saving work before closing, and (4) shutting down using the proper menu option rather than unplugging.

Keep instructions short, use pictures and repetition, and praise students for following steps correctly. Use simple safety rules: keep food/drinks away, use two hands for cables, ask a teacher if something is wrong.
