"Direct Memory Access. " DMA is a method of transferring data from the computer's RAM to another part of the computer without processing it using the CPU. While most data that is input or output from your computer is processed by the CPU, some data does not require processing, or can be processed by another device. In these situations, DMA can save processing time and is a more efficient way to move data from the computer's memory to other devices.

I disagree about how can DMA save data? Please explain for me.

DMA is only used when a large amount of data from i/o devices transferred to storage to the system so its answer is D.

Direct Memory Access (DMA) is a feature of computer systems that allows certain hardware subsystems to access main system memory (Random-Access Memory) independent of the Central Processing Unit (CPU).
