In DMA as the name suggest the memory can be accessed directly by i/o module. Thus overcome the drawback of programmed i/o and interrupt driven i/o where the CPU is responsible for extracting data from the memory for output & storing data in memory for input. DMA provids different information.

i) which operation (read/write) to be performed.

ii) The address of i/o device which is to be used.
