Challenge Problems

Push your limits with challenges.

Question 1

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.

💡 Hint: Visual structure using flowchart elements will help clarify the process.

Question 2

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?

💡 Hint: Consider scenarios where responsiveness is critical versus cases where resource conservation is critical.
