What is I/O (Input/Output) in Computing? | Built In

I/O Control Methods: Types & Explanation

For programmed 1 / O, Figure 7.5 indicates that the processor is stuck in a wait loop doing status checking of an I / O device. To increase efficiency, the I / O software could be written so that the processor periodically checks the status of the device. If the device is not ready, the processor can jump to other tasks. After some timed interval, the processor comes back to check status again. a. Consider the above scheme for outputting data one character at a time to a printer that operates at

SOLVED:A CPU with interrupt-driven I/O is busy servicing a disk request. While the CPU is midway through the disk-service routine, another I / O interrupt occurs. a) What happens next? b) Is it a problem? c) If not, why not? If so, what can be done about it?
