Problem
Solutions: DMA: Direct Memory Access. This is a chip that works with moving memory to and from disk drives. If the processor had to move each byte of information from disk into RAM, the computer would run very slowly. The processor in the computer tells the DMA to do the job instead. The DMA takes memory from the disk drive and puts it into a buffer in RAM, and then tells the processor when it is done. |
