Questions and Answers

What is the primary function of Direct Memory Access (DMA) in computer systems?

  • Improve the speed of the central processing unit (CPU)
  • Increase the involvement of the CPU in data transfers
  • Reduce the workload on the CPU during data transfer operations (correct)
  • Eliminate the need for peripherals in data transfers

    • How does DMA differ from traditional I/O operations involving the CPU?

  • Traditional I/O involves more memory allocation
  • DMA limits the types of peripherals that can be used
  • Traditional I/O requires constant CPU supervision
  • DMA uses a separate controller for data transfers (correct)

    • In a Multiprocessor system, what advantage does having multiple processors offer?

  • Decreases the overall system performance
  • Limits the number of tasks that can be executed simultaneously
  • Reduces the need for DMA controllers
  • Allows for parallel processing and faster task execution (correct)
