Estimate elevator algorithm-closest cylinder next, Mechanical Engineering

Assignment Help:

Disk requests come in to the disk driver for cylinders 10, 22, 20, 2, 40, 6, and 38, in that order. A seek takes 6 mes per cylinder moved. How much seek time is needed for

(a) First-come, first served.

(b) Closest cylinder next.

(c) Elevator algorithm (initially moving upward).
