  第1章 计算机基础知识
 本章内容要点:
 通过本章的学习应能了解计算机的发展过程、应用领域以及计算机的主要特征和未来发展趋势、数据化信息编码的概念与计算机的体系结构;掌握数据在计算机中的存储形式以及不同数制之间的相互转化、计算机系统组成的基本概念及基础知识;理解计算机的基本工作原理。
  1.1 概述
计算机(Computer)是二十世纪重要的发明之一,是科学技术和生产力的结晶,如今它已迅速应用于社会各个领域。掌握计算机基础知识和应用技术已成为高等技术人员所不可缺少的基本素质之一,因此对计算机基础文化知识的理解和掌握、计算机基础应用能力的培养,已成为当代大学生知识结构的重要组成部分。
  1.1.1 计算机及其分类
 计算机的分类方法很多,常见的有以下三种:
(1)从工作原理上来划分,可分为模拟计算机和数字计算机两大类。模拟计算机是通过电流、电压等连续变化的物理量来进行计算的,适用于过程的控制和模拟,其特点是运行速度快,而且输出为连续量,容易与实物相接近,抗干扰能力强,但缺点是运算精确度低,信息存储较难。
  数字计算机以数字电路为基础,用离散的数值“0”、“1”来表示所有的信息,因而它具有运算速度快、精确度高、通用性强等特点。
  (2)从用途上来划分,可分为通用计算机和专用计算机两大类。通用计算机用途广泛,它通过执行预先编制好的程序来完成指定的任务,程序内容不同,完成的任务也不一样,因而可用于科学计算、数据处理、事务管理、自动控制等。
