计算机英语课文翻译？第一个计算机,是建立在1940年代他们比汽车!自那时起电脑已经变得越来越小。桌面电脑大小的电视机。一个大的书的大小。现在我们已经掌上型电脑。他们有足够的放在你的口袋里像一块巧克力。那么，计算机英语课文翻译？一起来了解一下吧。
The most iportant system software that runs on a computer is the operating system. Every general-purpose computer must have an operating system to run other programs. Operating systems perfrom basic tasks ,such as recognizing input from the keyboard,sending output to the display screen,keeping trach of files and directories on the disk, and controlling peripheral devices such an disk drives and printers.
最iportant,计算机操作上运行。每一台通用计算机必须有一个操作来运行其他程序。操作perfrom基本任务,如识别的输入键盘,发送输出到显示屏,咋叻磁盘上的文件和目录,并控制外围设备这样一个磁盘驱动器和打印机。
The output is the last step in computer operation. It changes the computer’s results from binary machine language into a form that people can understand. There are several kinds of output devices.
Suppose a shoe store owner wants to know which style of shoe is selling best. He uses a printer. It actually prints, or types, the numbers of shoes sold on a long strip of paper. The machine printout shows him which shoes he should order. High-speed printers can print an entire ling at the same time turning out as many as twenty thousand lines a minute.
A city planner, though, may use her computer in a different way. She wants to plan a new bus route to serve the largest number of people. Using a plotter as the output, she gets a drawing, actually a map, showing the route chosen by the computer.
The telephone operator who looks up telephone numbers uses a computer. But she does not need a printed copy, nor a drawing of the number. Therefore, she has a computer terminal with a CTR .the screen flashes the number of a little while, and then it disappears, ready for the next request.
Students in many schools are taught by a computer.Some of these courses are in foreign languages.To learn a language,you must hear it spoken correctly.these computers have an audio output.They actually produce the sounds of the language perfectly pronounced.
The modern computer is truly an amazing machine.But it is not able to think ror itself.it is only as smart as the person who prepares its program.Nor can a computer produce correct answers unless it is fed correct data.
Many people are a little afraid of computers.They think of computers as machines with minds of their own.just remember this,though.A computer is nothing more than a human tool.It stretches our abilities.Just as you use a hammer to help you drive a nail into a wall,so you use a computer to help you solve a problem.Computers are our servants,not our masters.
The output is the last step in computer operation. It changes the
computer’s results from binary machine language into a form that
people can understand. There are several kinds of output devices.
输出是计算机处理的最后一步。
We have learned that all computer have similar capabilities and perform essntially the same functions , although some might be faster than others . We have also learned that a computer system has input ,output, storage , and processing components ; that the processor is the "intelligence "of a computer system ;and that a single computer system ; and that a single computer system may have several processors .We have discussed how data are represented inside a computer system in electronic states called bits.We are now ready to expose the inner workings of the nucleus of the computer system--the processor
计算机包括硬件和。硬件由输入设备、处理器、输出等设备组成。指的是程序。
首先，我们来介绍一下硬件，计算机的基本输入设备是键盘。处理器执行和贮存程序和数据。显示器是计算机的输出设备，作为处理器的窗口，它使用户能看到它的内容。打印机也是计算机的输出设备。
第二，我们来介绍一下程序，程序由许多命令组成。程序员或者计算机用户使通过他们来告诉计算机该做什么。磁盘操作是基本的程序之一。我们叫他DOS。

在键盘中央是字母键。它们的作用就像普通的打字机。数字键在字母键的右侧。在键盘的上排是功能键，他们属于特殊功能键。
键盘上还有三个特殊的功能键，它们是Esc(出口），Ctrl(控制）和Alt(互换）。如果您想知道更多信息，请查阅用户手册。

计算机包括硬件和．硬件包括输入设备，处理器和输出设备．依靠程序．首先，我来介绍一下硬件．计算机最基础的输入设备是键盘．鼠标也是输入设备．键盘是用来向计算机当中输入程序或资料的．处理器是用来执行和存储程序和资料的．显示器，是计算机的输出设备，为处理器提供了一个展示窗口．通过它可以让使用者看到内部的内容．打印机是计算机的输出设备．第二，我们来介绍一下程序．程序包括很多的指令．程序员或者是计算机使用者通过程序来告诉计算机要做些什么．一个最简单程序就是磁盘操作，我们称它为DOS．

标准键盘主要包括三个功能小组。
一、A computer system includes hardware and software. Hardware consists of input, processing and output devices. Software refers to programs.计算机包括硬件和。硬件包括输入设备、处理器和输出设备。指的是程序。
二、First, we introduce hardware. The basic input device of a computer system is keyboard. Mouse is input device, too. 首先，我来介绍一下硬件．计算机最基础的输入设备是键盘．鼠标也是输入设备．
三、Keyboard inputs data or programs into the computer. The processing device executes and stores programs and data. 键盘是用来向计算机当中输入程序或资料的．处理器是用来执行和存储程序和资料的．
四、Display, an output device of the computer, serves as a window on the processing device. It allows users to view its contents. 显示器，是计算机的输出设备，为处理器提供了一个展示窗口．通过它可以让使用者看到内部的内容。
以上就是计算机英语课文翻译的全部内容，经过Rational公司聘请了詹姆斯鲁博从通用电气在1994年，该公司成为源天的两个最流行的面向对象的建模方法：鲁博的对象建模技术（ OMT ） ，这是更好的面向对象分析（ OOA ） ，以及Grady Booch的Booch的方法。
