Unit 4 Computer networking说课稿

各位评委老师：
你们好。今天我说课的题目是《计算机英语》Unit 4 Computer networking。主要有以下几个部分：
一、说教材
我所讲的《计算机英语》选用的教材是穆志纯主编的2004年出版的《计算机英语》。
二、教学目标
根据学生的认知水平、教学大纲和本节内容我确定的教学目标是：
（1）能力目标
通过这门课的学习，提高学生阅读及理解专业英文资料的能力，掌握计算机专业文献的翻译技巧。
（2）知识目标
使学生掌握一定的计算机专业英语词汇，扩大知识面，同时掌握用英语表达专业知识的方法。
三、教学方法
本课程是旨在扩充学生的计算机专业英语单词量，提高他们的专业英文资料的阅读能力，并且学生能够写出简单的计算机专业性质的文章。所以在实际教学中，我很好地把握这一点。整个教学过程由听、读、写、说及词汇构成。采用多样化的教学方式，例如：分组讨论、课堂演讲、游戏等形式，充分调动学生的积极性和能动性，让学生更多地参与教学中，从而提高教学效果。

The physical components of a computer —The processor, memory, input divices, and output divices —are its hardware. You can see them, touch them and see them.
Software is a general term for programs. Software, in contrast, can not be seen, touched or felt. It is a series of instructions that guides a computer through some process. Computer software can be diveded into two very broad categories — systems software and applications software.
The former is often simply referred to as “systems”. These, when brought into internal memory, derect the computer to perform tasks.
The latter may be provided along with the hardware by a systems supplier as part of a computer product designed to answer a specific need in certain areas. Application programs also allow you to perform such tasks as solving statistical problems, keeping your company’s books or playing a computer games.
A computer is controlled by a stored program; thus, the first step in using the machine is copying the program from diskette into memory. Now, the processor can begin executing instructions. Input data from the keyboard are stored in memory. The processor manipulates the data, storing the results back into memory. Finally, the results are output.
A computer is a fast and efficient digital information processing system. It can accept, store, and process data and produce output results. It’s one of the greatest inventions in science and technology in the 20th century. It has had a long and deep social impact on human life and production.
Several computer generations occur in the history. The first digital computer ENIAC was invented in 1946. It marked the beginning of the first computer phase — mainframe phase. In fact, mainframes have had four generations of products, which are characterized by vacuum tubes, transistors, small and medium scale IC and super LSI circuits respectively.
In addition, the second-generation computers were given auxiliary storage, sometimes called external or secondary storage. Data were stored outside the computer on either magnetic tapes and magnetic disks for input and output operations increased the speed of the computer.
The keyboard, mouse, touch screen, light pen, bar codes which are widely used by supermarkets, microphone, for voice input, and so on.
