When dealing with multiple devices interrupts, which mechanism is easy to implement? a) Polling method. b) Vectored interrupts. c) Interrupt nesting. WebJan 19, 2024 · Interrupt Nesting: In this method, the I/O device is organized in a priority structure. Therefore, an interrupt request from a higher priority device is recognized whereas a request from a lower priority device is not. The processor accepts interrupts only from devices/processes having priority.
