0 TO 1999 = 2000 cylinders. Driver is serving request at cylinder 143, was previous at 125, and will serve queue of pending requests in FIFO order, is :
86,1470, 913,1774, 948, 1509, 1022, 1750, 130
Starting from current position, what is the total distance that the disk arm moves to satisfy all the pending requests for each of FCFS, SSTF, SCAN, LOOK, C-SCAN, C-LOOK disk-secheduling algorithm?
