Question 1 |
Dispatch latency is defined as
the speed of dispatching a process from running to the ready state | |
the time of dispatching a process from running to ready state and keeping the CPU idle | |
the time to stop one process and start running another one | |
none of these |
Question 1 Explanation:
Question 2 |
The operating system and the other processes are protected from being modified by an already running process because
they run at different time instants and not in parallel | |
they are in different logical addresses | |
they use a protection algorithm in the scheduler | |
every address generated by the CPU is being checked against the relocation and limit parameters |
Question 2 Explanation:
Question 3 |
Consider the following statements about process state transitions for a system using preemptive scheduling.
I. A running process can move to ready state.
II. A ready process can move to running state.
III. A blocked process can move to running state.
IV. A blocked process can move to ready state.
Which of the above statements are TRUE?
I. A running process can move to ready state.
II. A ready process can move to running state.
III. A blocked process can move to running state.
IV. A blocked process can move to ready state.
Which of the above statements are TRUE?
I, II and III only | |
II and III only | |
I, II and IV only | |
I, II, III and IV only |
Question 3 Explanation:
Question 4 |
Working Set (t,k) at an instant of time t is
the set of k future references that the OS will make | |
the set of future references that the OS will make in next t unit of time | |
the set of k references with high frequency | |
the k set of pages that have been referenced in the last t time units |
Question 4 Explanation:
Question 5 |

stack | |
queue | |
circular queue | |
tree |
