I/O Scheduler

An I/O Scheduler is a part of a computer's operating system that manages how input and output operations are handled, particularly for devices like hard drives and SSDs. It prioritizes and sequences tasks to ensure that data is read from or written to storage efficiently. By doing this, it optimizes performance and reduces wait times for applications that require data access, ensuring that multiple processes can run smoothly without bottlenecks. Essentially, the I/O Scheduler acts like a traffic director for data requests, helping to keep everything running in an orderly and timely fashion.
