The drive deal directly with the underlying hardware, the read and write devices work in accordance with the specific hardware register, complete the device polling, interrupt handling, DMA communication, physical memory to virtual memory mapping, and ultimately allow communication device can send and receive data , so that the display device can display text and pictures, log file and data storage equipment.
