自从1946年第一台电子计算机ENIAC问世以来,计算机技术一直不停地发展着,特别是进入七十年代以后,随着微电子技术取得的显著成就,其发展更为迅速。目前计算机已跨入全面采用大规模集成电路的第四代,并开始向具有知识处理功能的第五代过渡。在过去的十年里,对第五代计算机的基础工作已做了不少,现在正在进入实现阶段。甚至在这种计算机尚未真正出现之前,人们又在开始探讨和研究模仿人脑思维机理的神经网络计算机了,已有人称之为第六代计算机。因此在未来的十年中,第四代计算机将
Since the advent of ENIAC, the first electronic computer in 1946, computer technology has been constantly developing. Especially since the 1970s, with the remarkable achievements of microelectronic technology, its development has been more rapid. At present, the computer has entered the fourth generation that fully adopts the large scale integrated circuit and begins to transition to the fifth generation with knowledge processing function. In the past ten years, basic work on the fifth generation of computers has been done a lot, and it is now entering the realization phase. Even before this kind of computer has come into being, people are beginning to explore and study neural network computers that mimic the thinking mechanism of human brain, which has been called the sixth generation of computers. So in the next decade, the fourth generation of computers will be
