Frequently Asked Question on SSTF and C-LOOK
Which Disk Scheduling Algorithm has the best performance over all other Disk Scheduling Algorithms?
C-Look Disk Scheduling Algorithm has the best performance over all other Disk Scheduling Algorithms.
Why is SSTF not optimal?
There could be a risk of famine in SSTF. The SSTF algorithm is not the best one. Because we must determine the seek time in advance using this approach, there is a possibility of overhead in SSTF disk scheduling.Advantages
Is SSTF preemptive?
Because it is a non-preemptive CPU scheduling algorithm, once a process is assigned to a CPU, the CPU won’t be released until the process has finished running.
Can disk scheduling suffer from starvation due to the SSTF algorithm?
Finding the closest request has an overhead in the SSTF disk scheduling method. There is an overhead for locating end requests in this approach. The request that is farthest from the head in the SSTF disk scheduling algorithm will starve.
Difference Between SSTF and C-LOOK Disk Scheduling Algorithm
The secondary storage scheduling algorithm known as SSTF decides how the disk’s head and arm will move in response to read and write requests while in C-SCAN the head services request only in one direction(either left or right) until all the requests in this direction are not serviced and then jumps back to the farthest request in the other direction and services the remaining requests which gives a better uniform servicing as well as avoids wasting seek time for going till the end of the disk. You will discover the distinction between the SSTF and C-LOOK disk scheduling algorithms in this post. However, you must first understand the distinctions between the SSTF and C-LOOK disk scheduling algorithms.
