Draw the Gantt Chart of the sequence of execution of the processes using Round Robin Scheduling Algorithm considering the arrival time for all the process as ‘0’ and the quantum  time as ‘3’. Find the average waiting time of the processes

Suppose that an operating system supports two kinds of sequential processes: high-priority interactive processes, and low-priority non-interactive processes. The behavior of the high-priority processes is to alternate between periods of computation of duration Tc and periods of blocking (waiting for input) of duration Tb. The behavior of the low-priority processes is to compute constantly, with no blocking. The operating system’s scheduling policy is round-robin with a quantum q, where Tc < q. Scheduling decisions are made only when a quantum expires, or when the running process blocks. The scheduler selects a low-priority process to run only if no high-priority processes are ready. Suppose there is one high-priority process and one low-priority process in the system, and that both processes will run for a long time. For what fraction of the time does the low-priority process run?

Suppose we have four machines that are using the Berkeley algorithm for clock synchronization. The time daemon is running on machine MO. The other machines are named M1, M2, and M3. The time readings on the four machines are as follows wenty-four hour clocks are usedt. MO 09:10 M1: 08:30 M2 10:10 M3: 07:14 In the third step of the algorithm, what are the values that the time daemon sends to each machine? Assume that the time values are expressed in minutes. Below, these values are presented in a vector value sent to MO, value sent to MI, value sent to M2. value sent to M3I none of these O84, 44, 96, 321 O(24, 16, -84, 92) O192. 84, 16. -24 O-32, 76, 40

Consider the following snapshot of a system: Allocation Маx Available ABCD ABCD ABCD PO 2001 4212 3321 P1 3121 5252 P2 2103 2316 P3 1312 1424 P4 1432 3665 a. Illustrate that the system is in a safe state by demonstrating an order in which the processes may complete.

Consider the following set of 5 processes, with the length of the CPU-burst time given in milliseconds arriving at time 0: P1, P2, P3, P4, and P5 with corresponding burst time: 20, 47, 13, 17 and 22.   The processes are assumed to have arrived in the order P1, P2, P3, P4, P5, all at time 0. a. Calculate average waiting time for First Come First Serve and None Preemptive Shortest Job First CPU scheduling algorithms.        b. Which of the schedules in part a results in the minimal average waiting time (over all processes)?
