IO scheduler

An I/O scheduler is a component of an operating system that manages how input and output operations, like reading from or writing to a hard drive, are handled. It organizes these requests to optimize performance and minimize delays, ensuring that data is processed efficiently. By prioritizing certain tasks, the I/O scheduler makes sure that critical operations are completed quickly while also balancing the load on the system. This helps the computer run smoothly, especially when multiple applications are trying to access storage simultaneously.
