Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Consider a system using DMA versus programmed I/O for a large file transfer. Evaluate the time taken for both methods given a specific data size and type of operation. Which method is more efficient and why?

💡 Hint: Reflect on the operational differences between maintaining CPU involvement and allowing DMA to function independently.

Challenge 2 Hard

A hard disk has a high seek time but low rotational delay. Discuss the impact this has on overall performance and data retrieval times.

💡 Hint: Think about how each component's timing contributes to total access time.
