计算机专业英语影印版(Computing Essentials 2008)课后答案大全——第八单元Chapter 8 Secondary Storage

Crossword Puzzle Answers: Open Ended Questions: 1.Discuss the traditional and high-capacity floppy disks. The traditional floppy disk is the 1.44 MB 31/2-inch disk. The most common type is labeled 2HD, which means “two-sided, high-density” and have a capacity of 1.44 MB.Floppy disks have a thin exterior jacket made of hard plastic to protect the flexible disk inside. High-capacity disks, also known as floppy-disk cartridges, are rapidly replacing the traditional floppy disk. They are 31/2 inches in diameter, and are able to store more information, are thicker, and require special disk drives. 2.What are the three types of hard disks? Describe three ways to improve hard-disk performance. There are three types of hard disks: internal hard disk, hard-disk cartridge, and hard-disk pack.

计算机英语第三版课文翻译

第一单元：计算机与计算机科学 课文A：计算机概览 一、引言 计算机是一种电子设备，它能接收一套指令或一个程序，然后通过对数字数据进行运算 或对其他形式的信息进行处理来执行该程序。 要不是由于计算机的发展，现代的高科技世界是不可能产生的。不同类型和大小的计算 机在整个社会被用于存储和处理各种数据，从保密政府文件、银行交易到私人家庭账目。计 算机通过自动化技术开辟了制造业的新纪元，而且它们也增强了现代通信系统的性能。在几 乎每一个研究和应用技术领域，从构建宇宙模型到产生明天的气象报告，计算机都是必要的 工具，并且它们的应用本身就开辟了人们推测的新领域。数据库服务和计算机网络使各种各 样的信息源可供使用。同样的先进技术也使侵犯个人隐私和商业秘密成为可能。计算机犯罪 已经成为作为现代技术代价组成部分的许多风险之一。 二、历史 第一台加法机是法国科学家、数学家和哲学家布莱斯.帕斯卡于1642年设计的，它是数 字计算机的先驱。这个装置使用了一系列带有10个齿的轮子，每个齿代表从0到9的一个数字。轮子互相连接，从而通过按照正确的齿数向前转动轮子，就可以将数字彼此相加。17世纪70 年代，德国哲学家和数学家戈特弗里德.威廉.莱布尼兹对这台机器进行了改良，设计了一台 也能做乘法的机器。 法国发明家约瑟夫―玛丽.雅卡尔，在设计自动织机时，使用了穿孔的薄木板来控制复 杂图案的编织。在19世纪80年代期间，美国统计学家赫尔曼.何勒里斯，想出了使用类似雅 卡尔的木板那样的穿孔卡片来处理数据的主意。通过使用一种将穿孔卡片从电触点上移过的 系统，他得以为1890年的美国人口普查汇编统计信息。 1、分析机 也是在19世纪，英国数学家和发明家查尔斯.巴比奇，提出了现代数字计算机的原理。 他构想出旨在处理复杂数学题的若干机器，如差分机。许多历史学家认为，巴比奇及其合伙 人，数学家奥古斯塔.埃达.拜伦，是现代数字计算机的真正先驱。巴比奇的设计之一，分析 机，具有现代计算机的许多特征。它有一个以一叠穿孔卡片的形式存在的输入流、一个保存 数据的“仓库”、一个进行算术运算的“工厂”和一个产生永久性纪录的打印机。巴比奇未 能将这个想法付诸实践，尽管在那个时代它在技术上很可能是可行的。 2、早期的计算机 模拟计算机是19世纪末开始制造的。早期型号是靠转动的轴和齿轮来进行计算的。用任 何其他方法都难以计算的方程近似数值，可以用这样的机器来求得。开尔文勋爵制造了一台 机械潮汐预报器，这实际上就是一台专用模拟计算机。第一次和第二次世界大战期间，机械 模拟计算系统，以及后来的电动模拟计算系统，在潜艇上被用作鱼雷航线预测器，在飞机上 被用作轰炸瞄准具的控制器。有人还设计了另一个系统，用于预测密西西比河流域春天的洪 水。 3、电子计算机 第二次世界大战期间，以伦敦北面的布莱切利公园为工作地点的一组科学家和数学家， 制造了最早的全电子数字计算机之一：“巨人”。到1943年12月，这个包含了1500个真空管 的“巨人”开始运转了。它被以艾伦.图灵为首的小组用于破译德国用恩尼格码加密的无线 电报，他们的尝试大部分是成功的。 除此而外，在美国，约翰.阿塔纳索夫和克利福德.贝里早在1939年就在艾奥瓦州立学院

They are more powerful and reliable and, importantly, are very economical in terms of energy consumption. Their presence opens a new era in the field of IT technologies and means that the cloud technology is getting closer. These processors are primarily designed for servers, data centers (DPC) and supercomputers. The emergence of this class of devices is not accidental. According to the regional director of Intel in Russia and other CIS states Dmitri Konash who spoke at the event, the market of IT-technology is developing so rapidly that, according to forecasts, by 2015 there will be 15 billion devices connected to the Internet, and over 3 billion of active users. 上周，英特尔公司向俄罗斯和其它独联体国家的公众推出了英特尔Xeon E5-2600系列处理器，它们更加强大可靠，尤其是在能量消耗方面更加经济实惠。它们的问世意味着IT技术领域开始了一个新时代，标志着云技术距离我们越来越近。 这些处理器主要是为服务器、数字处理中心和超级计算机设计的。这种处理器的出现并非偶然。根据英特尔公司俄罗斯和其他独联体地区负责人Dmitri Konash就此事发表的看法，IT技术市场的发展速度极快，根据预测，到2015年与英特网连接的设施将有150亿，用户超过30亿。 [Ex 6] 1.

第9单元电子商务 第一部分听力和对话 对话：使用在线支付服务保护消费者的隐私 (Henry非常兴奋地在一家网上书店中发现了自己期待已久的图书，但是当得知系统要 求通过账号支付时，他犹豫了。) Henry: 最近互联网上信用卡账号的公然欺骗无疑为我们敲响了警钟。在进行在线交易时，我们并不知道要把自己的信用卡账号告诉谁。 Mark: 也许你可以使用第三方支付服务来保证在线支付更简单、更安全。 Henry: 什么是第三方支付服务？ Sophie: 简单地说，在使用第三方支付服务时，你可以把自己的资金转移到一个在线账号中，然后从那个账号中进行支付。这样就不用把自己的真实信用卡或银号账户信息暴露在网络上了。 Henry: 这种方法听起来更安全。有哪些第三方支付服务可以方便地使用？ Mark:在美国最受欢迎的服务是eBay公司掌控的PayPal,但也有一些其他的服务，如https://www.wendangku.net/doc/454097774.html, Payment等。以最简单的支付为例，例如在线拍卖或简单的网站销售，销售商只需要向买家提供他们的E-mail地址，而买家向销售商的PayPal账号进行适当的支付。Henry: 我明白了。 Sophie: 做出选择之后，建议你留意选择更加安全服务的一些细节。 Henry: 什么是更加安全服务的一些细节呢？ Sophie: 首先，阅读隐私政策，并确保自己同意其中的条款。如果不同意，可以继续选择其他的安全服务。此外，确认网站符合权威部门规定的特定的标准（查验同意的盖章）。这些的确都是非常重要但是有时被用户忽略的步骤。 Mark: 当使用第三方支付服务时，Henry,请记住千万不要回复来自第三方支付服务机构发送的要求确认如密码或其他私人身份识别信息等与账号细节相关的电子邮件。这些邮件很可能是身份盗窃骗局，如网络钓鱼。 Henry: 那么，怎样才能更安全地确认或处理我的账号细节呢？ Sophie: 如果需要确认或更新账号信息或者修改密码，我建议你可通过个人书签或者在浏览器中直接输入支付服务网站的URL来访问相应的网站。 Henry: 如何进一步确认卖家能够提供有效的支付服务？ Mark: 你可以通过查看卖家在几个月或更长的时间内是否为支付服务机构的有效成员来确定。有些网站还允许用户查看卖家的评价，虽然这些评价并不能作为保证，但是却是非常有用的信息。 Sophie: 切记，Henry,不要用自己的账号把资金转移到一个你不认识的人的账号里。这可能是一种高级的资金诈骗。还有，当你要购买一些诸如珠宝或者计算机等昂贵的物品时，尤其是在节假日或者商铺中售出的物品时，需要多加小心。 Henry: 好的。现在我对进行安全在线支付更加有信心了。非常感谢你们的见议。 练习

Unit 5 Section A Software Design （软件设计） Design is defined in [IEEE610.12-90] as both “the process of defining the architecture, components, interfaces, and other characteristics of a system or component ” and “the result of that process.” Viewed as a process, software design is the software engineering life cycle activity in which software requirements are analyzed in order to produce a description of the software ’s internal structure that will serve as the basis for its construction. More precisely, a software design (the result) must describe the software architecture -- that is how software is decomposed and organized into components -- and the interfaces between those components. It must also describe the components at a level of detail that enable their construction. Software design plays an important role in developing software: it allows software engineers to produce various models that form a kind of blueprint of the solution to be implemented. We can analyze and evaluate these models to determine whether or not they will allow us to fulfill the various requirements. We can also examine and evaluate various alternative solutions and trade-offs . Finally, we can use the resulting models to plan the subsequent development activities, in addition to using them as input and the starting point of construction and testing. In a standard listing of software life cycle processed such as IEEE/EIA 12207 Software Life Cycle Processes [IEEE 12207.0-96], software design consists of two activities that fit between software requirements analysis and software construction: Software architectural design (sometimes called top level design): describing software ’s top-level structure and organization and identifying the various components. Software detailed design: describing each component sufficiently to allow for its construction.
