What is a DMA (Direct Memory Access)?
Career: Dma
A DMA, or Direct Memory Access, is a feature in computer systems that allows certain hardware subsystems to access the main system memory independently of the central processing unit (CPU). This enables devices like disk drives, graphics cards, and network cards to transfer data to and from memory without burdening the CPU, leading to faster data transfer rates and improved system performance. DMA is commonly used in applications where large amounts of data need to be moved quickly, such as audio and video streaming or disk operations.
