WebThe alternative to Interrupt driven I/O is frequent polling to find out if the I/O device is done with it's last task. Polling leads to two types of parameters that affect I/O and CPU performance. Polling cost (CPU cost). Higher polling frequency => Higher cost. I/O operation delay due to I/O waiting for CPU to poll. WebJan 13, 2024 · In polling-based I/O, the I/O device is constantly polled to see if it requires a CPU. As a result, it transfers data to the main memory at a slow rate. DMA-based I/O transfer does not use the CPU to transmit data to the main memory, therefore it has the highest throughput. Hence the correct answer is DMA-based I/O transfer.
