Wie kan mij uitleggen wat DMA betekent ??

[Tony_Montana]

Kan iemand mij vertellen wat DMA betekent bij mijn hardeschijf instellingen. Als ik in systeem op schijfstations en dan op mijn hardeschijf instellingen klik staat er DMA erbij. Bij mij staat het uitgeschakeld is het verstandiger om het aan te zetten??

Ja, dat kan ik wel uitleggen

Direct Memory Access

Direct Memory Access is a capability provided by some computer bus architectures that allows data to be sent directly from an attached device (such as a disk drive) to the memory on the computer's motherboard. The microprocessor is freed from involvement with the data transfer, thus speeding up overall computer operation.
Usually a specified portion of memory is designated as an area to be used for direct memory access. In the Industry Standard Architecture bus standard, up to 16 megabytes of memory can be addressed for DMA. The Extended Industry Standard Architecture and Micro Channel Architecture standards allow access to the full range of memory addresses (assuming they're addressable with 32 bits). Peripheral Component Interconnect accomplishes DMA by using bus master (with the microprocessor "delegating" I/O control to the PCI controller).

An alternative to DMA is the Programmed Input/Output (Programmed Input/Output) interface in which all data transmitted between devices goes through the processor. A newer protocol for the ATA/IDE interface is Ultra DMA/33, which provides a burst data transfer rate up to 33 MB (megabyte) per second. Hard drives that come with Ultra DMA/33 also support PIO modes 1, 3, and 4, and multiword DMA mode 2 (at 16.6 megabytes per second).

Als het staat uitgeschakeld is het aan te raden om het aan te zetten ja.
