directing most of the computer system activities based on the

机相对于其他计算机的速度是快还是慢，除了别的因
素外，CPU的配置起着决定的作用。CPU是最复杂的计
算机系统设备，它根据提供的指令负责指挥协调计算
机系统的全部活动。当老一代计算机被新的一代计算
机代替的时候，CPU的实际尺寸往往变得越来越小，而
其速度和能力却增加了许多。这种变化的结果就使得
微机缩小得可以放在桌上或腿上。

tools ； drawing ， paint ， and image editing programs ； and
communication programs．Figuratively speaking，application
software sits on top of system software because it is unable to
run without the operating system and system software．
• 译：应用软件（又称作终端用户程序）是直接为用户
设计的具有专门功能的软件，或在某些情况下，为另
一种应用程序设计的软件，应用软件的例子有：字处
理器，数据库程序，网络浏览器，开发工具，绘图和
图像编辑程序，通信程序等。比喻地说，应用软件坐
在系统软件的上面，这是因为如果没有操作系统和系
统公用程序应用软件将不能运行。
