WebInterrupts originate from two places: internal and external to the CPU. Internal interrupts are generated by the CPU hardware itself, or commanded by software. External interrupts are those caused by peripheral devices. These types of interrupts are non-deterministic – they can occur at any time relative to anything else occurring in the CPU. WebInterrupt signals may be issued in response to hardware or software events. These are classified as hardware interrupts or software interrupts, respectively.

WebAn interrupt is an event that alters the sequence in which the processor executes instructions.. An 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: WebIn the case of timer interrupt, the kernel scheduler code may suspend the process that was running and allow another process to run. It is the presence of the scheduler code which enables multitasking. Software interrupts are processed much like hardware interrupts. However, they can only be generated by processes which are currently running.
