Answer» Direct Memory Access (DMA) is a FEATURE provided by some computer BUS architectures which PERMITS data to be sent directly from an external device (such as a disk drive) to the memory on the computer's motherboard. DMA ADDRESS deals with such physical addresses. It is an appliance which directly drives the data and address bus during data transfer. So, it is PURELY a physical address.
