WebJul 29, 2024 · First Come First Serve (FCFS) FCFS is the simplest disk scheduling algorithm. As the name suggests, this algorithm entertains requests in the order they … WebA disk in a computer is a magnetic storing drive which is divided into different surfaces. All these surfaces or platters rotate as one unit, and the speed at which it rotates is as high as 5k to 10k RPM. Further, the exterior of each tray is structured to store data. Each of the track or plate is sub-divided into different blocks.

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 ... WebIn contrast, the C-LOOK disk scheduling algorithm outperforms all other disk scheduling techniques. LOOK disk scheduling algorithm has better throughput and a faster response time with low variance. In contrast, the C-LOOK disk scheduling algorithm gives uniform waiting time and response time.
