Learn the SSTF (Shortest Seek Time First) disk scheduling algorithm in this 13-minute operating systems tutorial. Explore how this algorithm optimizes disk head movement by selecting the request with the shortest seek time from the current head position, reducing overall seek time and improving system performance. Understand the implementation details, advantages, and potential drawbacks of SSTF compared to other disk scheduling algorithms like FCFS and SCAN. Master the step-by-step process of how the disk scheduler determines the next request to service based on proximity to the current head position, and analyze practical examples demonstrating the algorithm's efficiency in minimizing disk arm movement.
