Answer 1

Option C

DMA is Direct Memory Access.

Answer 2

Direct Memory Access (DMA) is an important data transfer technique.

Explanation:

• Direct access (DMA) could be a technique that permits input/output (I/O) devices to send or receive information on to or from the most memory, bypassing the central processor to hurry up memory operations.

• The process is managed by a chip called a DMA controller (DMAC).

• A defined portion of memory is used to send data directly from a peripheral to the motherboard while not involving the microchip, so the method doesn't interfere with the overall operation.

• DMA channels are accustomed communicate data between the computer peripheral and therefore the system memory.

Hence, Direct Memory Access (DMA) is an important data transfer technique.
