What does DMAC mean or stand for ?

DMA stands for Direct Memory Access and is a piece of hardware inside the computer that allows transfer of data between the Input or Output devices,the RAM as well as the processor.

The CPU is used to compute and process these data blocks and is transferred via the channels HLD and HLDA in both the directions.The DMAC makes the access to the memory faster and more efficient and without this device programs and graphics would run much slower.
