Direct Memory Access (DMA) is a capability provided by some computer bus architectures that enables data to be sent directly from an attached device, such as a disk drive, to the main memory on the computer'smotherboard. The microprocessor, or central processing unit (CPU), is freed from i...
Without Direct Memory Access, when the CPU uses programmed inputs/outputs, it is usually fully occupied during the entire read or write operation, so it cannot perform other tasks. With DMA, the CPU first initiates the transfer, then performs other operations while the transfer is in progress,...

Short for direct memory access, a technique for transferring data from main memory to a device without passing it through the CPU. Computers that have DMA channels can transfer data to and from devices much more quickly than computers without a DMA channel can. This is useful for making quick...
What is Remote Direct Memory Access (RDMA)? Remote Direct Memory Access is a technology that enables two networked computers to exchange data in main memory without relying on the processor,cacheor operating system of either computer. Like locally based Direct Memory Access (DMA), RDMA improves ...
Direct memory access facilitates data transfers between peripheral devices and their hosts. Learn DMA meaning with Techopedia.

Remote Direct Memory Access (RDMA): RDMA is a technology designed to solve the problem of long delay and packet loss during network transmission. It can directly extract data from storage devices to the storage area of computing devices over the network, without affecting the operation and respons...
Along with Secure Boot and TPM 2.0, Windows Server Secured-core uses Boot DMA protection on compatible processors that have the Input/Output Memory Management Unit (IOMMU). For example, Intel VT-D or AMD-Vi. With boot DMA protection, systems are protected from Direct Memory Access (DMA) ...
