[10 Marks Question 9 a) Consider five processes with the following service times: t(p0) = 350ms t(pl)= 125ms t(p2) = 475ms (p3) = 250ms T(P4) = 75ms The processes enter the ready queue in the listed order. In the context of process scheduling consider a time slice size of 100ms for a round robin scheduling algorithm. Consider also the processes that have the highest priority in the listed order: pl has highest priority, p4 has the lowest priority. The switching time is 10 units for context switching. Demonstrate and calculate the average waiting time and average turnaround time for round robin with overhead scheduling algorithms. Also briefly explain average waiting time and average turnaround time
