LOOK Disk Scheduling Algorithm in Operating System

Learn the LOOK disk scheduling algorithm in this 10-minute tutorial that explains how this operating system technique optimizes disk head movement for efficient data access. Explore the fundamental concepts behind LOOK scheduling, understand how it differs from other disk scheduling algorithms like SCAN and C-SCAN, and discover how it reduces seek time by moving the disk head in one direction until no more requests exist in that direction before reversing. Master the step-by-step process of implementing LOOK algorithm, analyze its advantages and disadvantages, and examine practical examples that demonstrate how this algorithm handles disk I/O requests to minimize total head movement and improve system performance.
