Understanding Interrupt Requests and Priority Inversion

What is a possible reason for a high-end computer system experiencing slow performance?

• Excessive interrupt requests

• Overheating of the CPU

• Outdated software

• Lack of sufficient RAM

What is the role of an interrupt handler in a computer system?

• To execute the main program

• To control input/output operations

• To manage memory allocation

• To handle interrupt requests

How does a computer system prioritize tasks?

• Randomly

• By the order of arrival

• According to the urgency and importance

• Based on the size of the task

What can cause stuttering and higher latency in a computer system?

• Insufficient cooling

• Large numbers of interrupt requests

• Frequent software updates

• Low battery power

What is priority inversion?

• A situation where low priority tasks are ignored

• A method to speed up task execution

• A scenario where a high priority task is blocked by a lower priority task

• A condition where task priorities are reversed

What caused the Sojourner Rover on Mars to experience system resets?

• A power failure

• A hardware malfunction

• A priority inversion issue

• A software bug in the navigation system

How was the priority inversion issue on the Sojourner Rover resolved?

• By rebooting the system

• By adjusting the task priorities manually

• By replacing faulty hardware

• By sending a software patch from Earth

What is a common consequence of a computer spending too much time deciding what to do?

• Increased processing speed

• System slowdown

• Improved multitasking

• Reduced power consumption

What personal anecdote does the narrator share about dealing with priority inversion?
