在很早很早以前,人类在同大自然作斗争中碰到了必须计算的问题,于是简单的运算工具应运而生。自世界第一台电子计算机产生后,电子信息技术迅猛发展,人类工业文明进入到了第三个革命阶段,即以计算机和网络技术为代表的信息革命时代。当今世界个人计算机(PC)年产量数以千万计,直达亿台高峰;超级计算机已达每秒百亿次浮点运算、如今目标指向每秒万亿次浮点运算;计算机网络的范围跨国、跨洲通达全球,最大的国际计算机网络INTERNET 的用户数以千万计。更为突出的是计算机的渗透力非常之大,与其他科技行业的结合力非常之强,
Earlier and long ago, human beings encountered some problems that must be calculated in their fight against nature. So simple computing tools came into being. Since the birth of the world’s first electronic computer, the rapid development of electronic information technology has brought the human industrial civilization to the third stage of revolution, that is, the era of information revolution represented by computer and network technology. In today’s world, the annual output of personal computers (PCs) reaches tens of millions of meters, reaching a peak of 100 million. The supercomputers have reached 10 billion floating-point operations per second, and today the target points to one trillion floating-point operations per second. The range of computer networks covers many countries , Intercontinental accessible the world, the largest international computer network INTERNET tens of millions of users. More prominent is the penetration of the computer is very large, and the binding force of other science and technology industry is very strong,
