In the field of microprocessor what is DMA?why it is used?

Answer Posted / shankar

whn a text file is o/p to a disk drive, we are concerned
with transferring data from memeory to that drive. yet with
programmed or interrupt driven I/O approches tht data mst
be read from memeory into the cpu and then transffered to
the didk drive . the microproccessor is na
unnecessary "middleman" in this process with the result
that the transfer rate is decresed. the dma is approach is
to turn off the processor and let the disk drive access the
data file in memeory itself : a sort of direct memory
access.
