Web12.2 Explain why SSTF scheduling tends to favor the middle cylinders of a disk over the innermost and outermost cylinders. Answer: The SSTF algorithm is biased toward the middle cylinders in much the same way the SCAN algorithm is. Since, in the SSTF algorithm, the closest cylinder is always chosen, then all middle cylinder references will ... WebThe purpose of disk scheduling algorithms is to reduce the total seek time. Various disk scheduling algorithms are-. FCFS Algorithm. SSTF Algorithm. SCAN Algorithm. C-SCAN Algorithm. LOOK Algorithm. C-LOOK … WebYes, disk scheduling other than FCFS scheduling can be useful in a single-user environment. SSTF is useful when the data sets are near each other. In the elevator scheduling, we saw that the effects are optimal because it is more efficient than FCFS but unlike SSTF, there are no starvation. cherry lake sedge meadow state natural area
