On a disk with 1000 cylinders, number 0 to 999, compute thenumber of tracks the disk arm must move to satisfy all the requestsin the disk queue. Assume the last request serviced was at track345 and the head is moving toward track 0. The queue in FIFO ordercontains requests for the following tracks: 123, 847, 692, 475,105, 376.

Answer the below questions for thefollowing disk scheduling algorithms: FCFS, SSTF, SCAN andLOOK.

  1. Draw a diagram for the arm movement and
  2. Calculate the total number of tracks and the average number oftracks travelled by the head to satisfy the requests in part-a(Details of
