Correct Answer:
B. Allow data to bypass the CPU
Correct answer: Allow data to bypass the CPU. DMA lets devices transfer data directly to or from memory without going through the CPU.
Background: This frees the CPU to do other work.
- Storing data: DMA is not mainly for storing data.
- Printing data: DMA is not for printing data.
- Deleting data: DMA is not for deleting data.
Did you know? Disk drives and sound cards often use DMA.
Memory trick: DMA = direct, no CPU middleman.
