(10 Marks) BN104 – Operating System – Final Assessment ‐ Trimester 2, 2021 Page 6 of 8 SECONTION B: Problem based questions (18+12+5=35 Marks) Question 4 [18 Marks (3 for each scheme)] Suppose the following disk request sequence (track numbers) for a disk with 100 tracks is given: 23, 89, 32, 42, 97, 35, and 87. Assume that the initial position of the Read and Write (R/W) head is on track 75. Draw the diagrams for arm movement for the seek strategies given below. Calculate the total and average number of tracks travelled and conclude with which strategy performed best in the given scenario. a) FCFS b) SSTF c) SCAN d) C‐SCAN e) LOOK f) C‐LOOK Question 5 [12 Marks (3 for each scheme)] The following are a few of the process scheduling algorithms that could be used in a system: a) Shortest Job Next (SJN) b) Shortest Remaining Time (SRT) c) Round Robin (RR) (use 3 as time quantum size) d) Non Pre‐emptive Priority Table 1: Process Table Suppose arrival time for P1, P2, P3, P4, and P5 is 0, 0, 1, 2 and 3 respectively. Also note that 1 represents the highest priority. Draw a job completion timeline and calculate the turnaround time for each of the given scheduling algorithms.
