What is the benefit of using CPU throttling in laptops?
- A.
It reduces the processing time needed by end-user applications.
- B.
It reduces CPU power consumption and heat production.
- C.
It reduces the amount of CPU resources needed by system applications.
- D.
It avoids the need to increase the clock speed of the laptop processor.
Correct Answer
B. It reduces CPU power consumption and heat production.Explanation
CPU throttling is a technique used in laptops to reduce the power consumption and heat production of the CPU. By decreasing the clock speed of the processor, it limits the amount of power consumed and the amount of heat generated. This helps in improving the battery life of the laptop and preventing overheating, which can lead to performance issues and hardware damage. Additionally, CPU throttling allows the laptop to operate more quietly as the fans don't need to work as hard to cool down the CPU.Rate this question:

What is the proper way to clean optical drives?
- A.
Spray ionized solution inside the drive.
- B.
Use an electrostatic vacuum cleaner
- C.
Blow the dust with compressed air from the inside.
- D.
Use a cleaning disc for optical drives
Correct Answer
D. Use a cleaning disc for optical drivesExplanation
The proper way to clean optical drives is by using a cleaning disc specifically designed for optical drives. These cleaning discs have small brushes or microfiber cloths that can effectively remove dust and debris from the laser lens of the drive. Spraying ionized solution inside the drive or using an electrostatic vacuum cleaner can potentially damage the delicate components of the drive. Blowing dust with compressed air may also cause the dust to spread and settle on other parts of the drive. Therefore, using a cleaning disc is the safest and most effective method for cleaning optical drives.Rate this question:
