1. Consider three processes (process id 0, 1, 2 respectively) with computing bursts time units of 3, 4 and 7 respectively. All processes arrive at the same time. Consider the scheduling algorithm with the longest remaining time first (LRTF). In LRTF ties are broken by giving priority to the process with the lowest process id. What is the average waiting time for the three processes? Describe in depth. 2. Consider the following set of processes, with the arrival times and the CPU-burst times given in milliseconds Process Arrival Time Burst Time P1 5 P2 3 P3 2 3 P4 4 What is the average waiting time for these processes with the pre-emptive shortest remaining time first (SRTF) algorithm? Describe in depth.
