## Direct Memory Access Transfers

Direct memory access, or DMA, is a feature that allows hardware devices to transfer data directly to or from the system memory without involving the CPU. In the context of trading, this allows network cards to write incoming market data packets directly into the application's memory space.

This offloads the task of data movement from the CPU, allowing it to focus on processing the data and executing trades. DMA is a critical component for achieving high throughput and low latency in trading systems.

It prevents the CPU from becoming a bottleneck during periods of high data volume. Implementing DMA requires careful management of memory buffers and hardware configuration.

It is a standard technique in high-performance networking and driver development. By using DMA, the system achieves a more efficient and responsive data path.

It is an essential technology for modern, high-speed financial trading infrastructure.
