What is the performance advantage in having device drivers and devices synchronize by means of device interrupts?

Using device interrupts for synchronization between device drivers and devices enhances performance by allowing the CPU to execute other tasks instead of polling for device readiness. This event-driven approach reduces CPU usage and latency, as the CPU can respond instantly when an interrupt signals that the device requires attention. Consequently, it improves overall system efficiency, enabling better multitasking and responsiveness in applications.
