DMA (Direct Memory Access)

DMA (Direct Memory Access) is a technology that allows hardware devices, like hard drives or graphics cards, to transfer data directly to or from a computer’s memory without involving the CPU. This process speeds up data transfer, reducing the CPU’s workload and improving overall system performance. Instead of the CPU handling each tiny step, DMA enables devices to communicate with memory independently, ensuring faster and more efficient data movement for tasks like streaming videos, gaming, or large file transfers.
