What is Understanding Direct Memory Access (DMA) about?

1. Direct memory access (DMA) allows data transfers between system memory and I/O devices without intervention from the microprocessor, improving server performance. 2. The DMA controller integrated into the processor board manages all DMA transfers, allowing the data to bypass the microprocessor as it moves between memory and devices. 3. During a DMA transfer, the requesting device arbitrates for control of the bus, and the DMA controller then takes control of the bus to perform the data transfer when gra
