Which of the following statements about synchronous and asynchronous I/O is NOT true?
An ISR is invoked on completion of I/O in synchronous I/O but not in asynchronous I/O
In both synchronous and asynchronous I/O, an ISR (Interrupt Service Routine) is invoked after completion of the I/O
A process making a synchronous I/O call waits until I/O is complete, but a process making an asynchronous I/O call does not wait for completion of the I/O
In the case of synchronous I/O, the process waiting for the completion of I/O is woken up by the ISR that is invoked after the completion of I/O
