An operating system uses shortest remaining time first scheduling algorithm for pre-emptive scheduling of processes. Consider the following set of processes with their arrival times and CPU burst times (in milliseconds):
The average waiting time (in milliseconds) of the processes is _________.
-
- 5.5
- 1.5
- 5
- 55
Correct Option: A
The Gantt chart for SRTF scheduling algorithm is :
| Average waiting time = | = | = 5.5 | ||
| 4 | 4 |
