| 单词 | simultaneous input /output |
| 释义 | simultaneous input /outputAn ability that the computers can handle other operations concurrently with input and output operations. Most often this is accomplished using buffers that hold input /output data and information as it arrives (and on a temporary basis), while other operations are executed by the CPU. Thus, the computer need not wait for data to arrive from the very slow I /O units or terminals and may instead take it in massive quantities from the faster part of the buffer.; 计算机进行输入输出操作的同时具有处理其它操作的能力。通常是使用缓冲器把输入输出 数据和信息暂时保存下来,其它操作则由中央处理机(CPU)执行,这样,计算机就不必等 待从速度很慢的输入输出设备(或终端)来的数据,而可以从快速的缓冲器得到数据。 |
