Questions and Answers

What is one advantage of a multiprocessing operating system?

  • Decreased throughput as processors increase
  • Reduced system complexity with fewer processors
  • Increased reliability due to distributing tasks among several processors (correct)
  • Limited work capability with multiple processors

    • Which characteristic is a disadvantage of a multitasking operating system?

  • Increased CPU heat generation (correct)
