The method which offers higher speeds of I/O transfers is __________
A)interrupts
B)memory mapping
C)program-controlled i/o
D)dma

Question

Quizplus · Accepted Answer

DMA (Direct Memory Access) allows the transfer of data between memory and a peripheral device without continuous intervention by the CPU, enabling faster data transfer rates compared to methods that require more CPU intervention, such as interrupts and program-controlled I/O. Memory mapping is a method of accessing memory, but it does not inherently offer higher speeds of I/O transfers compared to DMA.
