Question

In case of DMA, after the completion of the transfer, the processor is required to be notified of the completion. This is done through.

• A. Burst Signal
• B. Interrupt Signal
• C. Acknowledgement Signal
• D. Completion Signal

Hint:

DMA works independently of the processor for data transfer and uses an interrupt signal to notify the processor when the transfer is complete.

Answer 1

The Correct Option is B

Upon completion of a Direct Memory Access (DMA) data transfer between peripherals and memory, the processor requires notification to resume operations. An Interrupt signal typically provides this notification, momentarily halting the processor to signal DMA completion.
