Question 1

What is the main advantage of DMA over interrupt-driven I/O?

  • More context switching
  • Less CPU suspension
  • Increased complexity

💡 Hint: Think about how CPU activities are changed during DMA usage.

Question 2

True or False: In burst transfer mode, the CPU is interrupted multiple times.

  • True
  • False

💡 Hint: Consider how burst operations handle data compared to cycle stealing.

Challenge Problems

Push your limits with challenges.

Question 1

You have a system using DMA to transfer 100MB of data. If the cycle stealing mode transfers 1KB at a time, how many interruptions occur during the transfer?

💡 Hint: Convert MB to KB to simplify calculations.

Question 2

Design an experiment to compare the performance of burst mode vs. cycle stealing in a real-world application.

💡 Hint: Focus on measuring transfer times and CPU idle periods.
