Direct Memory Access Definition from Encyclopedia Dictionaries & Glossaries

Wikipedia English - The Free Encyclopedia
Direct memory access
Direct memory access (DMA) is a feature of modern computers that allows certain hardware subsystems within the computer to access system memory for reading and/or writing independently of the central processing unit. Many hardware systems use DMA including disk drive controllers, graphics cardsnetwork cards, and sound cards. Computers that have DMA channels can transfer data to and from devices with much less CPU overhead than computers without a DMA channel.
