微型计算机自七十年代初研制以来,已经从第一代发展到第三代。从民用到军用,已出现几十个品种和系列。在功能上,这些微型计机具有从计算器到小型计算机的功能;从设计上微型机也有系列化、标准化的追求,也就是说,微型机满足从系统计设上是通用的、在具体的使用上是专用的普遍要求;从计算机结构上,微弛机所使用的大规 Microcomputer has been developed from the first generation to the third generation since it was developed in the early 1970s. From civil to military use, there have been dozens of varieties and series. Functionally, these microcomputers have functions from calculators to mini-computers; mini-computers are also designed to be serialized and standardized in their design, that is to say, mini-computers are versatile in terms of system design. In specific Use is a special requirement of universal; From the computer structure, micro-relaxation machines used by the rules
