Web2 feb. 2024 · Propagate the InterruptedException. We can allow the InterruptedException to propagate up the call stack, for example, by adding a throws clause to each method in turn and letting the caller determine how to handle the interrupt. This can involve our not catching the exception or catching and rethrowing it. WebI/O Interrupt Handling — An Overview After a program issues an I/O operation to a specific device, an interrupt is returned from the device indicating the status of the I/O operation. CP processes the interrupt first: it converts the results into a format your virtual machine … WebInterrupt-Driven I/O. The primary disadvantage of PIO is that the CPU is totally involved in the slow I/O operation, and spends most of its time remaining idle called busy waiting.
