How many head movements are needed to move from cylinder 14 to 124 in an FCFS scenario?
Press to flip
110 head movements (124 - 14)
In FCFS disk scheduling, what is the significance of the initial read/write head position?
The initial position is the starting point from which head movements are calculated.
Given an initial head position of 53 and the next request at 98, how many head movements are required to fulfill the request?
45 head movements (98 - 53)
What is the total head movement when moving from cylinder 183 to 37 in FCFS scheduling?
146 head movements (183 - 37)
Calculate the head movement when moving from cylinder 37 to 122 in FCFS disk scheduling.
85 head movements (122 - 37)
Given the disk queue requests: 98, 183, 37, 122, 14, 124, 65, 67 with an initial head position at 53, what is the total head movement in an FCFS algorithm?
640 total head movements
Determine the head movement in FCFS from cylinder 122 to 14.
108 head movements (122 - 14)
Why might FCFS not be an ideal scheduling algorithm for disk management?
Because it does not optimize for the shortest seek time, leading to potentially long wait times and inefficient head movement.
If a disk queue request is at 183 and the head is currently at 98, how many movements are required in FCFS scheduling?
85 head movements (183 - 98)
How does the FCFS scheduling algorithm decide the order of job execution?
Jobs are executed in the order they arrive.
What is a major disadvantage of FCFS scheduling in disk management?
It can lead to high total head movement and long wait times for subsequent requests.
If the read/write head moves from cylinder 124 to 65, how many head movements occur in FCFS?
59 head movements (124 - 65)
What is the head movement required to move from cylinder 65 to 67 in FCFS scheduling?
2 head movements (67 - 65)
What does FCFS stand for in the context of scheduling algorithms?
First Come First Serve
What is the primary advantage of FCFS scheduling?
It is simple and easy to implement.
