第1章 计算机基础知识
现代电子计算机是20世纪人类伟大的发明创造之一。自从1946年诞生台电子数字计算机以来,计算机科学已成为20世纪发展快的一门学科,计算机的性能越来越高,价格越来越便宜,应用越来越广泛。尤其微型计算机的出现和计算机网络的发展,使得计算机及其应用广泛渗透到社会的各个领域。计算机技术的迅猛发展,以及硬件系统和软件系统不断升级换代,使得以计算机技术为基础的高新技术被广泛应用,极大地促进了生产力和信息化社会的发展,对人类社会的生产方式、工作方式、生活方式和学习方式都产生了极其深刻的影响。正是由于计算机技术的发展引发了信息革命,从而使人们从工业社会步入信息社会,把人类带入了一个信息化的新时代。
  1.1 计算机的发展
  1.1.1 计算机的演变
在漫漫历史长河中,人们使用的计算工具,从简单到复杂、从初级到高级,逐步发展,人类从未停止过追求高速计算工具的脚步。其中有几件事对现代计算机的发明有重要意义:一是中国古代发明的直到今天还在使用的算盘,被人们誉为“原始计算机”;二是1642年法国物理学家帕斯卡发明了齿轮式加减法器;三是1673年德国数学家莱布尼茨制成了机械式计算器,可以进行乘除运算(见图1.1);四是1822年英国数学家查尔斯·巴贝奇提出了差分机和分析机的构想,具有输入、处理、存储、输出及控制五个基本装置,而这些正是现代意义上的计算机所具备的,如图1.2所示。
