can an interrupt move a process to waiting state?

#1

can an interrupt move a process to waiting state? Why a process moved to ready state on an interrupt? Does I/O from the same process move the process into waiting state?

#2

Interrupt is when a process is stopped from performing its required job when it is in RUN state.

  1. The interrupt may be due to completion of time slice of the process. In this case process goes back to READY state and waits for its execution.
  2. The interrupt may be due to entry of some higher priority process in the READY state. In this case process goes back to READY state and waits for its execution.
  3. The interrupt can be from Input Output device. In this case process goes to WAIT state, waiting for I/O device for its completion. So yes, I/O from same process moves it to WAIT state.

Hope this helps. :slight_smile:
