disk scheduling

Disk scheduling is the process computers use to determine the order in which data requests are handled on a storage device like a hard drive. When multiple programs request data, the system organizes these requests to minimize the time the disk head moves around, improving efficiency. Think of it as arranging shoppers in a line based on their checkout order to reduce waiting and travel time. Effective scheduling ensures faster access to data, reduces delays, and boosts overall system performance. Different algorithms, such as FIFO, SSTF, or SCAN, manage this sequencing to optimize speed and reduce wear on the hardware.
