Booting

Booting is the process of starting the computer or preparing the computer for use.

Starting up a Micro Computer System

When the power button is pressed to boot up, the PC goes through a process called power- on – self test (POST). This POST enables the computer to read several files to remind itself what it should be doing and to perform a complex series of tests to make sure all its hardware components are working properly.

When the computer is booted up, an electrical current travels to the microprocessor and resets the chip to clear its memory. During reset, the microprocessor sends a command to the computer’s read only memory (ROM) chips to run the computer’s basic input/output system (BIOS) boot program. Thereafter, the boot program connects the hard drive, loading windows XP/VISTA/7 core system files through the microprocessor and loading the device driver software needed to allow communication between the operating system and the PC’s hardware.

After communicating with the video card to create the desktop environment, windows operating system then opens the Startup folder which is immediately accessed from the hard drive and loaded through the microprocessor into RAM, after which the computer is ready for use.

There are two types of booting:

1. Cold booting
2. Warm booting

Cold booting: The process of switching the computer by pressing the power switch on the system unit.

Warm booting: The process of restarting the computer by pressing the reset button on the system unit or by using the ctrl + Alt + Del key.

Presentation:

• Use visual aids to illustrate the booting process.
• Encourage student participation through questions and discussions.

Teacher’s Activities:

• Present the topic using simplified language.
• Provide examples to enhance understanding.
• Facilitate discussions and answer students’ questions.

Learners’ Activities:

• Listen attentively to the explanation.
• Participate actively in discussions.
• Ask questions for clarification.

Assessment:

• Observe students’ participation and engagement during the lesson.
• Ask comprehension questions to assess understanding.
• Assign a brief quiz at the end of the lesson to test knowledge retention.

Class Activity Discussion 

1. What is booting?
   • Booting is how we start a computer or get it ready to use.
2. What does POST stand for?
   • POST stands for Power-On Self Test.
3. Why does a computer perform POST during booting?
   • To make sure all its parts are working correctly.
4. What is BIOS?
   • BIOS is a program that starts the computer and prepares it for use.
5. How can we do a cold boot?
   • By pressing the power button on the computer.
6. What is warm booting?
   • Restarting the computer using the reset button or Ctrl + Alt + Del.
7. What happens after the computer is booted up?
   • It loads the operating system and gets ready to use.
8. What does USB stand for?
   • USB stands for Universal Serial Bus.
9. What is the function of the mouse in booting?
   • The mouse helps in controlling the computer’s pointer on the screen.
10. How many buttons does a mouse have?
    • A mouse usually has two buttons: left and right.
11. What is the left button of the mouse used for?
    • It is used for clicking or selecting objects.
12. What is the role of the mouse ball?
    • The mouse ball helps in moving the pointer on the screen.
13. Why is booting important for a computer?
    • Booting prepares the computer for use by loading necessary programs.
14. Can we use a keyboard shortcut for warm booting?
    • Yes, we can use Ctrl + Alt + Del for warm booting.
15. What is the ultimate goal of booting?
    • To make the computer ready for us to start using it.
