Question 4
Identify the scheduler which involves only in the decision for the selection of partially serviced jobs?
Question 5
Consider three CPU-intensive processes, which require 10, 20 and 30 time units and arrive at times 0, 2 and 6, respectively. How many context switches are needed if the operating system implements a shortest remaining time first scheduling algorithm? Do not count the context switches at time zero and at the end.
Question 6
Consider the following table of arrival time and burst time for three processes P0, P1 and P2.
The pre-emptive shortest job first scheduling algorithm is used. Scheduling is carried out only at arrival or completion of processes. What is the average waiting time for the three processes?
