What is "DMA" (Direct Memory Access) and why is it beneficial?
Correct! Well done.
Incorrect.
The correct answer is A) A feature that allows peripherals to transfer data directly to/from memory without continuous CPU intervention, freeing the CPU to perform other tasks during the transfer
A
Correct Answer
A feature that allows peripherals to transfer data directly to/from memory without continuous CPU intervention, freeing the CPU to perform other tasks during the transfer
Explanation
Without DMA, the CPU would need to manage every byte of a transfer, wasting cycles; DMA controllers handle bulk transfers independently, significantly improving overall system efficiency for I/O-heavy tasks.
