A action in which peripheral controls regulate the transfer of data between the central processor and peripheral devices. Specifically, they reconcile the mechanical speeds of the peripheral devices with the electronic speed of the central processor, and minimize the interruption of central processor activity due to peripheral data transfers.; 外围控制器调整中央处理器与外围设备之间的数据传送的工作过程。特别是这些控制设备使 得中央处理器的电子速度与外围设备的机械速度协调起来,把由于外部数据传输造成的中央处 理器活动的中断降低到最少。
