    A process is best defined as:

  2. ٢

    Which of these is part of a process?

  3. ٣

    Which process state means the process is waiting to be assigned to a processor?

  4. ٤

    Which information is NOT stored in the Process Control Block (PCB)?

  5. ٥

    The ready queue contains processes that are:

  6. ٦

    The long-term scheduler controls:

  7. ٧

    An I/O-bound process typically has:

  8. ٨

    During a context switch, the system:

  9. ٩

    In UNIX, which system call replaces a process's memory space with a new program?

  10. ١٠

    Cascading termination refers to:

  11. ١١

    Process execution must progress in a sequential fashion.

  12. ١٢

    The short-term scheduler is invoked infrequently and may be slow.

  13. ١٣

    A process that has just finished waiting for an I/O event moves directly to the running state.

  14. ١٤

    Context-switch time is useful work performed by the CPU.

  15. ١٥

    In UNIX, the fork() system call creates a new process.

  16. ١٦

    A CPU-bound process spends more time doing I/O than computation.

  17. ١٧

    The PCB stores the process state, program counter, and CPU registers.

  18. ١٨

    The long-term scheduler is also called the job scheduler.

  19. ١٩

    A parent process may abort a child that has exceeded its allocated resources.

  20. ٢٠
