- Round Robin Process Suppose we have a four (4) core processor and all processes are designed to be multi-threaded. Now, like all processors with more than one core, they have the ability to perform multiple tasks at the same time. If there are four (4) with the following CPU and I/O cycles according to the table below, calculate the times for the Round Robin scheduling process (view image): Where A,B,C,D correspond to A=6, B=3, C=5, D=8.ey I am trying to better understand termination values and have been trying to do a few practice questions involving CPU scheduling. I am having trouble calculating the terminated states for the question below. For the sample question below, Could you please give the exact termination time for each P value. A. Round Robin with a 1 ms time sliceB. Shortest Job First (assuming CPU bursts are known, and thus do not have to be estimated) Please also provide a brief explanation for why this is the case thanks. Processes P1, P2, and P3 are run concurrently on a computer system with one CPU. Process P1arrives first at time 0, and uses the CPU for 6 ms before finishing. Process P2 arrives shortly afterP1, still at time 0. Process P2 loops two times; for each iteration of the loop, P2 uses the CPU for1 ms and then it does I/O for 5 ms. Process P3 is identical to P2, but arrives shortly after P2, stillat time 0. Assume that there is no overhead due to context switches.Draw the Gantt chart, Calculate the Average Turnaround Time AND Average Waiting Time for the following processes using Round Robin Scheduling. Assume that the time quantum is 4 ms. Processes Arrival Time CPU BURST Time P1 0 8 P2 1 4 P3 2 2 P4 3 1
