In the field of microprocessor what is DMA?why it is used?
Answer Posted / veer thakur
The transer of data between a fast storage device such as

the CPU, by removing the CPU from the path and letting the
peripheral device manage the memory buses directly would
improve the speed of the transfer, this transfer technique
is called DIRECT MEMORY ACCESS(DMA)...
