After the completion of the DMA transfer, the processor is notified by:
Correct answer: B. Interrupt signal
- A. Acknowledge signal
- B. Interrupt signal
- C. Deadlock
- D. DMA
Explanation
Interrupt signal is the mechanism used by the DMA controller to notify the processor that the DMA transfer has finished. When the transfer is complete, the DMA controller generates an interrupt signal that the processor is programmed to recognize and respond to. Upon receiving the interrupt signal, the processor can then resume its normal operations and handle any necessary post-transfer tasks
