Which of the following are causes of power supply overheating?
-
Overloading the power supply
-
Fan Failure
-
Dirt or Dust
-
All of the above
Correct Answer
A. All of the aboveExplanation
Overloading the power supply can cause overheating because it puts excessive strain on the components, leading to increased heat production. Fan failure can also cause overheating as the fan is responsible for cooling the power supply. If the fan is not working properly or stops working altogether, the power supply will not be adequately cooled. Dirt or dust can obstruct the airflow and prevent proper cooling, resulting in overheating. Therefore, all of the mentioned factors can contribute to power supply overheating.Rate this question:

What happens when the CMOS battery fails?
-
Cmos configuration is lost
-
The computer won't boot
-
The computer is destroyed
-
The motherboard is dead
Correct Answer
A. Cmos configuration is lostExplanation
When the CMOS battery fails, the CMOS configuration is lost. The CMOS (Complementary Metal-Oxide-Semiconductor) configuration stores important settings for the computer, such as date and time, boot order, and hardware settings. Without the CMOS battery, the computer is unable to retain these settings, causing them to reset to default values. This can lead to issues such as incorrect date and time, inability to boot from the correct device, or hardware not being recognized properly. However, it does not result in the destruction of the computer or the death of the motherboard.Rate this question:

Which of the following best describes hyperthreading?
-
Processing two execution threads simultaneously
-
Overclocking your CPU
-
Processing two execution threads one after another
-
Processing two applications simultaneously
Correct Answer
A. Processing two execution threads simultaneouslyExplanation
Hyperthreading is a technology that allows a single physical processor core to behave like two logical processors. It achieves this by duplicating certain components within the processor, enabling it to handle multiple execution threads simultaneously. This means that the processor can work on two different tasks at the same time, improving overall performance and efficiency. Therefore, the answer "Processing two execution threads simultaneously" accurately describes hyperthreading.Rate this question:
