WebProgrammed I/O Interrupt Initiated I/O; Its module is treated as a slow module. Its module is faster than programmed I/O module. It is quite easy to program and understand. It can be tricky and complicated to understand if one uses low level language. WebExplanation: DMA is an interface that provides i/o transfer of data directly to and from the memory unit and the peripheral. In this technique, an external device is used to control data transfer. External device generates address and control signals required to control data transfer and allows peripheral devices to directly access memory.
