WebInterrupt-Driven I/O In order to allow the CPU to do other tasks while I/O operations are running, it is necessary to use interrupts. When I/O is done in this manner, the CPU programs the control registers of an I/O device, calls the scheduler, and then runs a different process until the I/O device indicates that it is done. WebAn interrupt might be planned (specifically requested by the currently running program) or unplanned (caused by an event that might or might not be related to the currently running program). z/OS® uses six types of interrupts, as follows: ...
