consider a hard disk device with cylinder for the questions if the head initially serves a request cylinder number and receives the lO disk request shown below
Assume that once lO disk requests and serviced, the will not make any other movement when
having a tie FCFS lO disk request:
aif using first come serve FCFS scheduling algorithm what is total head movement cost is cylinder
bif using shortest seek time first SSTFwhat is total head movement cost is is cylinder
cif using SCAN scheduling algorithm Moving to the left direction, towards lower cylinder numberswhat is total head movement cost is cylinder
dif using LOOK scheduling algorithm Moving to the left direction, towards lower cylinder numberswhat is total head movement cost is cylinder
