Questions and Answers

What are the three main advantages of a multiprocessor system?

  • Increased throughput, reduced energy consumption, and improved scalability
  • Increased throughput, economy of scale, and increased reliability (correct)
  • Increased throughput, reduced memory usage, and improved fault tolerance
  • Increased throughput, reduced cost, and improved performance

What is the difference between asymmetric multiprocessing and symmetric multiprocessing (SMP)?

  • Asymmetric uses a single processor, while SMP uses multiple processors
  • Asymmetric is more common in small systems, while SMP is more common in large systems
  • Asymmetric uses a master processor to schedule and allocate work, while SMP has each processor running an identical copy of the OS (correct)
  • Asymmetric is more efficient for parallel processing, while SMP is better for serial processing

What is the main reason for using multiple hardware and software duplicates in a fault-tolerant multiprocessor system?

  • To improve load balancing
  • To take the majority result and mask component failures (correct)
  • To provide backup in case of a system crash
  • To increase processing power
