Direct Memory Access (DMA) is a capability provided by some computer bus
architectures that allows data to be sent directly from an attached
device (such as a disk drive) to the memory on the computer's
motherboard. The microprocessor is freed from involvement with the data
transfer, thus speeding up overall computer operation.
