电子技术经过第一代的电子管技术、第二代的晶体管技术和第三代的集成电路技术之后,已进入到第四代的微电子技术.作为第四代的微电子技术的核心和精髓是用超大规模集成电路做成的微型计算机和微处理机.电子计算机的问世,并不亚于一七七六年英国瓦特发明蒸汽机所开拓的第一次工业革命.人们称赞我们已进入了电脑时代,这标志着第二次工业革命.微处理机和微型计 After the first generation of electronic tube technology, the second generation of transistor technology and the third generation of integrated circuit technology, has entered the fourth generation of microelectronics.As the fourth generation of microelectronic technology, the core and essence of Microcomputers and microprocessors made of very large scale integrated circuits. The advent of electronic computers was as good as that of the first industrial revolution pioneered by Watts in the United Kingdom in 1776. People praised us for having entered the computer age , Marking the second industrial revolution. Microprocessors and micrometers
