Define I/O interface. Comparison between programmed I/O, Interrupt driven I/O and direct memory access (DMA).[10]
--- An Input/Output (I/O) Interface provides a method for transferring information between internal storage (CPU/Memory) and external I/O devices (peripherals). It is needed because several differences exist between the computer and peripheral devices: Difference Explanation ------ Speed mismatch...
