Understanding Power-On Sequence in a Computer
When you switch on the CPU, it initiates a process that powers various components of the computer system. Here’s a detailed explanation of what happens:
1. Electrical Supply Activation
- When the power button is pressed, the power supply unit (PSU) provides electricity to the system.
- This electrical surge is crucial for activating all connected devices.
2. CPU and Internal Components
- The central processing unit (CPU) is one of the first parts to receive power.
- Other internal components like RAM and storage drives (HDD/SSD) also get powered up.
3. Peripheral Devices Activation
- As the system boots up, it communicates with peripheral devices, such as:
- Monitor: Displays visual output and is powered on to show the boot process.
- Keyboard: Powers up to allow user input during the boot sequence.
- Mouse: Activates for navigation once the operating system starts.
4. Overall System Readiness
- All these components work together to ensure the computer is ready for use.
- Any failure in powering these devices can lead to a malfunctioning system.
Conclusion
Thus, the correct answer is option 'D', as switching on the CPU powers on the monitor, keyboard, and mouse, making them essential components for the computer's operation.
