WebNov 29, 2024 · The processor performs other tasks while the I/O operation is being performed. When the I/O operation is completed, the I/O module interrupts the processor letting the processor know the operation is completed. Its module is faster than the programmed I/O module. The processor actually starts the I/O device and instructs it to … WebThis can be overcome by the employment of AN interrupt facility. This forms the idea for the Interrupt Initiated I/O.
