Question 1.
What is an interrupt?
Show hintHide hint
Think about how the CPU reacts when a device signals it is ready.
Question 2.
What does the I/O module do?
Show hintHide hint
Consider the role of the middleman in communication.
3Question 3.
What is the primary function of an interrupt?
- A) To increase CPU speed
- B) To stop CPU execution temporarily
- C) To improve memory capacity
Show hintHide hint
Think of a phone call interrupting a conversation.
4Question 4.
True or False: Context switching involves saving the state of the CPU before processing interrupts.
- True
- False
Show hintHide hint
Consider what needs to be paused during an interrupt.
Question 5.
Design a simple flowchart depicting the process of handling an interrupt. Include steps for saving the state, executing the ISR, and restoring the state. Explain each step briefly.
Show hintHide hint
Visual structure using flowchart elements will help clarify the process.
Question 6.
Debate the advantages and disadvantages of interrupt-driven I/O compared to programmed I/O under different system loads. What systems would prefer each method?
Show hintHide hint
Consider scenarios where responsiveness is critical versus cases where resource conservation is critical.
