Question 2.
What is the purpose of an interrupt service routine (ISR)?
Show hintHide hint
Consider what happens after a device signals for attention.
3Question 3.
What does an interrupt signal to the CPU?
- The CPU should stop everything
- A device needs attention
- Nothing significant
Show hintHide hint

4Question 4.
True or false: An ISR can be deferred if a higher priority interrupt occurs.
- True
- False
Show hintHide hint
Consider the implications of prioritizing tasks.
Question 5.
Design a system using both hardware and software polling mechanisms. Discuss when you would use each.
Show hintHide hint
Consider the speed and reliability needs of the devices.
Question 6.
Imagine a scenario where multiple devices raise interrupts simultaneously. How would you manage their priorities effectively?
Show hintHide hint
Think about emergency systems where certain devices must always be prioritized.
