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...
Short fordirectmemoryaccess, a technique for transferringdatafrommain memoryto adevicewithout passing it through theCPU.Computersthat have DMAchannelscan transfer data to and from devices much more quickly than computers without a DMA channel can. This is useful for making quickbackupsand forreal-ti...
Direct Memory Access can be abbreviated to DMA, which is a feature of computer systems. It allows input/output (I/O) devices to access the main system memory (random-access memory), independent of the central processing unit (CPU), which speeds up memory operations. Tip:You may be interest...
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 throughput and performance because it frees up r...
1. DMA (Direct Memory Access) is a feature of some computer bus architectures that allows data to be sent from a storage device to memory without using the CPU (Central Processing Unit). Because DMA frees the processor from involvement in the transfer process, it tends to be faster than PI...
Secured-core servers can also isolate of driver access to memory with Direct Memory Access (DMA) protection. UEFI secure boot UEFI secure boot is a security standard that protects your servers from malicious rootkits. Secure boot ensures the server boots only firmware and software trusted by the ...

its bandwidth – which relates directly to its speed performance capability (with more lines usually resulting in higher performance). Buses may use multiple protocols for exchanging data among devices – including interruptions, polling methods, direct memory access (DMA), clock signals and serial ...
Secured-core servers measure and verify boot processes with Dynamic Root of Trust for Measurement (DRTM) technology. Secured-core servers can also isolate of driver access to memory with Direct Memory Access (DMA) protection.UEFI secure bootUEFI secure boot is a security standard that protects ...
The GeoPort was designed as an additional direct memory access (DMA) channel for internal sound hardware like modems and fax machines. Although the earliest versions were not fast enough to operate communication devices, later versions of the AV series were more than able to handle the processing...
