The Win32_DMAChannel class represents a direct memory access (DMA) channel on a Win32 computer system. DMA is a method of moving data from a device to memory (or vice versa) without the help of the microprocessor. The system board uses a DMA controller to handle a fixed number of channels, each of which can be used by one (and only one) device at a time.
