计算机专业英语影印版(Computing Essentials 2008课后答案大全)第三单元Basic Application Software
Crossword Puzzle Answers:Open Ended Questions:1.Explain the difference between general-purpose and special-purpose applications.General-purpose applications are widely used in nearly every discipline and occupation. They include word processors, spreadsheets, database management systems, and presentation graphics.special-purpose applications are more narrowly focused on specific disciplines and occupations, such as graphics programs, audio and video editors,2.Discuss the common features of most software programs. Describe the new interfaceintroduced with 2007 Microsoft Office.The newest Office version, 2007 Microsoft Office, has a redesigned interface that is intended to make it easier for users to find and use all the features of an application. This new designintroduces ribbons, contextual tabs, galleries, and more.• Ribbons replace menus and toolbars by organizing commonly used commands into a set of tabs.These tabs display command buttons that are the most relevant to the tasks being performed by the user.• Contextual tabs are tabs that appear automatically. These tabs only appear when they are needed and anticipate the next operations to be performed by the user.• Galleries simplify the process of making a selection from a list of alternatives. This isaccomplished by replacing many dialog boxes with visual presentations of potential results.This new interface is the first major change in over a decade.3.What is the difference between a function and a formula? How is a formula related to what-if analysis?A formula is an instruction to calculate or process. Functions are prewritten formulas providedby the spreadsheet program that perform calculations such as adding a series of cells. If a change is made to one or more numbers in a spreadsheet, all related formulas will automaticallyrecalculate and charts will be recreated. Observing these changes is what-if analysis.4.What are presentation graphics programs? How are they used?Presentation graphics are programs that combine a variety of visual objects to create attractive, visually interesting presentations. They are excellent tools to communicate a message and to persuade people.5.What is the difference between an integrated package and a software suite? Whatare the advantages and disadvantages of each?An integrated package is a single program that provides the functionality of a wordprocessor, spreadsheet, database manager, and more. The primary disadvantage of an integrated package is that the capabilities of each function (such as word processing) are not as extensive as in the individual programs (such as Microsoft Word). The primary advantages are cost and simplicity.A software suite is a collection of separate application programs bundled together andsold as a group. While the applications function exactly the same whether purchased in a suite or separately, it is significantly less expensive to buy a suite of applications than to buy each application separately.1.

28
现行教育方式与人工智能学习特点 高度重合
数学教学：
应试教育：中小学强调计算、题型和公式套用， 缺少逻辑推理训练；高校数学知识碎片化，仍 是简单套公式应付考试，会解题但往往不会活 用数学工具，如根据实际问题建立数学模型
人工智能：擅长计算，已有Matlab等非常强大 的数学和统计软件工具，计算能力远超人类
数学教育看起来只是一种知识教育，但本质上是一种 素质教育
告诉你如何学习好计算机英语？
计算机英语的学习不同于考 "托"考"G"，无法靠短期的突击来完成。长期的日常学习尤为重要。所谓的日常学习并不需要你抛开工作，安排专门的时间，而是边用边学。比如，你为了解决编程上的一个问题，查阅英文的帮助或技术资料。然而，不少程序员不太喜欢看英文，他们喜欢使用中文版的软件，喜欢汉化的帮助，喜欢读翻译好的书。这实际上就错过了许多日常学习计算机英语的机会。不可否认，读中文肯定比读英文方便，节省时间，但从长期的发展来看，弊大于利。这种对翻译的依赖使许多程序员失去了获取一手资料的宝贵机会。
教材的体系结构--目前计算机英语教材主要分为按语法体系组织和按计算机体系组织的两种结构。如果你是初中级的英语水平建议使用前者，如果你是中高级的英语水平建议使用后者。
教材的易用性--教材的易用性是指教材的编排是否符合人们的学习习惯。虽然计算机英语是专业课程教材，但如果编排活泼、图文并茂、注解查阅方便肯定能调动学习的兴趣，降低阅读的难度。这方面国内的教材应该多向国外的教材学习。
然而国内许多大学的计算机英语课程作为专业英语教学起步较晚，而早期出版的计算机英语教材大多出自于任课老师收集的计算机英文资料，教材规划不够系统，编排也比较简单。这些教材虽然使用的学校较多，为早期的计算机英语教学做出过不可磨灭的贡献，但致命的弱点是内容陈旧、与时代脱节。最典型的代表是清华大学出版社的《计算机英语》，该书最新版本是1997年更新的，里面还充斥着Dos这样的陈旧内容。有些老师苦于没有新颖实用的计算机英语教材，于是一本国外的计算机入门读物《Computing Essentials》(McGraw-Hill出版公司)被许多大学选用为计算机英语教材，效果极佳。这本书现在已经由高等教育出版社影印发行，书名是《计算机专业英语》。该书的特点是:时效性强(版本更新快)，新颖实用，编排活泼。但对于中高级英语水平的专业开发人员未免有点太浅。

Coaxial cable- a high-frequency transmission cable with a single solid-copper core. Fiber-optic cable - transmits data as pulses of light through tiny tubes of glass. WirelessInfrared - uses infrared light waves to communicate over short distances. Broadcast radio sends and receive radio signals through transceivers. Microwave - uses high-frequency radio waves. Satellite - uses satellites orbiting above the earth as microwave relay stations. 3.Identify the standard Internet protocol and discuss its essential features.The standard protocol for the Internet is TCP/IP (transmission control protocol/Internet protocol). Every computer on the Internet has a unique numeric address called an IP address. Information is reformatted or broken down into small parts called packets. 4.Define and discuss the four principal network topologies.S tar network - a number of small computers or peripheral devices are linked to a central unit. Bus network - each device in the network handles its own communications control. Ring network - each device is connected to two other devices, forming a ring. Hierarchical network— consists of several computers linked to a central host computer, and also hosts to other, smaller computers or to peripheral devices. 5.Define and discuss the three most common network strategies.Terminal network system,- processing power is centralized in one large computer, usually a mainframe. - use one computer to coordinate and supply services to other Client/server network systems - use one computer to coordinate and supply services to other nodes on the network. Peer-to-peer network system, nodes have equal authority and can act as both clients and servers.

【关键词】：计算机专业英语，教学，改革一、前言IT 行业的产品和技术日新月异，无论是了解和学习最新的计算机技术，还是使用最新的计算机软硬件产品，都离不开对其原版技术文档和相关资料的理解。
专业性和针对性很强的计算机专业英语是掌握和理解计算机新技术的强有力的工具，是IT从业人员必备的重要工具。
职业技术学院计算机专业培养的是IT行业应用型人才。
计算机专业英语和计算机专业两种知识相辅相成，学好计算机专业英语，能透彻理解计算机的应用、语言和命令，通过计算机网络了解最新的计算机信息，反之在计算机专业学习和实践中不断学习提高计算机英语水平。
二、高职院校计算机专业英语现状笔者根据对高职院校计算机专业英语教学现状的初步调研，结合自身对计算机专业英语多年教学工作的亲身体会，总结了目前高职院校计算机英语课程主要存在一下两大问题。
1、重视程度低，课程设置的目的和教学目标不明确；学生兴趣不高。
在众多高职院校中，计算机英语普遍被设置为考察科目，英语基础较好的学生把专业英语等同于公共英语，或是公共英语的延续，只要在原有英语基础上多记些专业术语即可；而基础较差的学生看到专业英语复杂的长句，繁杂的构词时，翻译时的蹩脚，立刻丧失了学习的信心，甚至有了学习专业英语的心里障碍；加之考察课的缘故，没有明确的教学目的和教学目标，这些使得教师的教和学生的学都缺乏了动力，导致了不重视的结果。
2、教材内容陈旧，与企业需求脱节；体系结构不科学，教学手段落后。
目前大多高职院校使用的教材是1997年清华大学出版社出版的《计算机英语》，无庸置疑，该教材为早期的计算机英语教学做出了不可磨灭的贡献。

学习专业英语的心得总结范例
学习专业英语的心得总结范例随着英语教育的重要性日益凸显，学英语专业的同学越来越多了。
下面是店铺为大家整理的学习专业英语的心得总结，供你参考!学习专业英语的心得总结篇1努力目标：掌握大量的计算机英语术语和缩略语;熟练掌握计算机英语中语法和惯用法的表达方式和功能;能阅读英文文档和技术资料，阅读熟读在100词/分钟以上;能借助字典翻译专业技术图书;能和别人用英语交流;能流利的表达自己的观点;能使用英文编写简单的技术文档和程序注释。
努力方式：1选一本适合自己的计算机英语教材：一本国外的计算机入门读物《Computing Essentials》(McGraw-Hill出版公司)被许多大学选用为计算机英语教材，效果极佳。
这本书现在已经由高等教育出版社影印发行，书名是《计算机专业英语》。
该书的特点是：时效性强(版本更新快)，新颖实用，编排活泼。
但对于中高级英语水平的专业开发人员未免有点太浅。
一本非常适合于软件开发人员的《计算机英语》，该书已经由机械工业出版社出版，是该社"重点大学计算机教材"系列中的一本。
需要说明的是该书最适合的读者对象为英语达到CET4的程序员，因为该书的选材直接来自国外计算机教材和出版物、技术文档和专业论文、IT精英的言论以及计算机方面的大百科全书。
在日常工作中大量阅读英文书籍和资料是提高计算机英语水平的最佳途径。
保证一年至少读1-2本原版影印的计算机书，并坚持读完。
目前市场上大量的计算机原版影印图书为我们提供了绝好的机会。
阅读英文计算机图书一开始是"啃"的感觉，比较费时费力，对于不太好读的地方，不妨拿起笔来逐行逐字翻译出来，这样对提高英语水平很有帮助。
对于有经验的程序员可以利用自己的专业背景知识和上下文(Context)进行大胆推测，这样有利于提高阅读速度。
即使是不求甚解，也不要紧，你可以通过多读同类书来弥补。
原版计算机书读多了，你会发现一些很有规律的东西和一些常用的词汇，这些来自实践的经验非常宝贵，并让你终生受益。
