MCQ On Fundamentals Of Process Management In OS Part-1

Here are the collections of MCQ on fundamentals of process management in OS including multiple-choice questions about process management in the operating system. It includes objective-type questions on the two-state process model, the five-state model for the creation and termination of processes, and the characteristics of the suspended process.

13. In …………………… state, the process is in secondary memory and awaiting an event.
A) Ready
B) Blocked
C) Blocked/Suspend

A) blocked, blocked/suspend
B) ready, ready/suspend
C) blocked/suspend, ready/suspend
D) ready/suspend, ready

15. A process in the ……………….. state is moved to the ………….. state if there are no ready processes, then at least one blocked process is swapped out to make room for another process that is not blocked.
A) blocked, blocked/suspend
B) ready, ready/suspend
C) blocked/suspend, ready/suspend
D) ready/suspend, ready

16. A process in the ………………… state is moved to the …………….. when there are no ready processes in main memory, the operating system will need to bring one in to continue execution.
A) blocked, blocked/suspend
B) ready, ready/suspend
C) blocked/suspend, ready/suspend

B) ii and iii only
C) i and iii only
D) All i, ii and iii

20. Which of the following is/are the reasons for the process suspension
i) The operating system needs to release sufficient main memory to bring in a process that is ready to execute.
