Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

In a computer system, how does using indirect addressing improve memory utilization? Discuss scenarios where it would be essential.

💡 Hint: Consider why direct addressing may worry about limits.

Challenge 2 Hard

Devise a scenario with multiple interrupts occurring during a complex instruction execution. Describe how the CPU handles these interrupts and ensures that the instruction flow is maintained.

💡 Hint: Think about the layering of tasks and execution.
