Direct Memory Access (DMA) is a feature that allows certain hardware components to access the system memory independently of the central processing unit (CPU). This capability enables faster data transfer between devices, such as disk drives and memory, by bypassing the CPU and freeing it to perform other tasks. DMA enhances overall system efficiency and performance, especially in data-intensive applications. It is commonly used in scenarios like disk I/O operations, audio and video processing, and network communications.
