In the context of Operating system process scheduling, if W represents Wait Time, R represents Run Time, T represents Turnaround time, S represents Response time, then which of the following is correct option with respect to given diagram?
- A.
Time1:W, Time2:R, Time3:T, Time4:S (b) (c) (d)
- B.
Time1:S, Time2:W, Time3:R, Time4:T
- C.
Time1:W, Time2:R, Time3:S, Time4:T
- D.
Time1:R, Time2:S, Time3:W, Time4:T
Attempted by 169 students.
Show answer & explanation
Correct answer: C
The diagram illustrates the timeline of a process in an operating system. We can identify the following time intervals:
- Time1 spans from Arrival to Execution Start. This is the Wait Time (W).
- Time4 spans from Arrival to Finish. This is the Turnaround Time (T).
- Time3 spans from Execution Start to Finish. This is the Run Time (R).
- Time2 spans from Execution Start to First Output. This interval is associated with the Response Time (S) in this context.
Therefore, the correct mapping identifies Time1 as Wait Time (W) and Time4 as Turnaround Time (T).
