Final answer:
Operating systems perform device drivers, device allocation, and I/O scheduling to manage I/O devices.
Step-by-step explanation:
An operating system performs various activities to manage I/O devices. These activities include:
- Device Drivers: Device drivers are used by the operating system to interface with the I/O devices. Device drivers are pieces of software that let the operating system communicate and control with particular hardware.
- Device Allocation: The distribution of I/O devices among various users or processes is controlled by the operating system. It avoids conflicts and makes sure that every process or user has equitable access to the devices.
- I/O Scheduling: The operating system determines the sequence in which the I/O requests from various processes are handled and schedules them. In order to maximize the use of the I/O devices and provide effective I/O operations, scheduling algorithms are employed.
