如果说机器可能代替人进行体力劳动,那么电子计算机就能够代替人做脑力劳动。当前科学技术发展很快,最突出的有五个项目:电子计算机、遗传工程、激光、光导纤维和海洋开发。在五个项目中电子计算机排在第一位,可见它的重要性。电子计算机是一种能够自动、快速和大量计算的电子机器。它具有精确度高又能记忆和逻辑判断的功能。本文准备从电子计算机的构造和原理方面来谈谈电子计算机是怎样进行脑力劳动的。 If the machine can replace manual labor, then the computer can do mental work on behalf of people. At present, science and technology are developing rapidly. Among the most prominent are five projects: computers, genetic engineering, lasers, optical fibers and marine development. In five projects ranked first in the computer, we can see its importance. An electronic computer is an electronic machine that can be automated, fast and massively calculated. It has the function of high precision and memory and logic judgment. This article intends to talk about how electronic computers work in terms of the structure and principles of electronic computers.
