What is the main advantage of DMA over interrupt-driven I/O?
💡 Hint: Think about the CPU's ability to multitask.
True or False: In burst mode, the DMA transfers data in chunks over several cycles.
💡 Hint: Consider how burst mode operates compared to other modes.

Challenge Problems
Push your limits with advanced challenges
If a CPU can handle one instruction every 10 nanoseconds and a DMA transfer takes 1 second for 1 MB of data, how many instructions can the CPU complete during one transfer?
💡 Hint: Think about how many cycles fit in that timeframe.
Devise a hypothetical performance metric assessing the efficiency of using DMA vs. interrupt-driven I/O in a single-bus system.
💡 Hint: Evaluate operational roles and timing conflicts in data transfers.
