WebINTERRUPT-INITIATED I/O special command informed to interface about received input signal when data are available in I/O device when interface determine the device is ready for data transfer then it generate interrupt request to computer computer instantly reply to interface , means it stop any kind of working by CPU & accept the interrupt Web1. Programmed I/O Some modes are using CPU as intermediate path. 2. Interrupt- Initiated I/O 3. Direct Memory Access (DMA) Programmed I/O => Each data transfer is initiated by an instruction in the program. => Once a data transfer is initiated, the CPU is required to monitor the interface to see when a transfer can again be made.
