三、完型填空题(每空1分,共30分)

1. Software testing, which is defined as the execution of a program to find its faults, is a vital part of the software lifecycle. There are different types of testing, mainly, they are black box testing or functional testing, which tests whether the output is the expected result with the input; and white box testing (or glass box testing) which is performed to reveal problems with the structure of a program . Debugging is the process of analyzing and locating bugs when software does not behave as expected. Software testing is a much more thorough means of identifying software bugs. Therefore, debugging supports testing other than replacing testing.

2. ASCII is the acronym for American Standard Code for Information Interchange ASCII is a code for representing English characters as numbers, with each letter assigned a number from 0 to 127(decimal). For example, the ASCII code for uppercase M is 77 (decimal). Most computers use ASCII codes to represent text, which makes it possible to transfer data from one computer to another.

Text files stored in ASCII format are sometimes called ASCII files. Text editors and word processors are usually capable of storing data in ASCII format, although ASCII format it not always the default storage format. Most data files, particularly if they contain numeric data, are not stored in ASCII format. Executable programs are never stored in ASCII format.

The standard ASCII character set uses just 7 bits for each character. There are several larger character sets that use 8 bits, which gives them 128 additional extensions The extra characters are used to represent non-English characters, graphics symbols, and mathematical symbols. Several companies and organizations have proposed characters for these 128 characters. The DOS operating system uses a superset of ASCII called extended ASCII or high ASCII. A more universal standard is the ISO Latin 1 set of characters, which is used by many operating systems, as well as Web browsers. Another set of codes that is used on large IBM computers is EBCDIC.

3. The operating system is a set of system programs that, when executed, controls the operation of the computer. Sophisticated operating systems increase the cost and consequently decrease the efficiency of using a computer. Operating systems provide a software platform on top of which other programs, called application programs, can run. The application programs must be written to run on top of a particular operating system. Your choice of operating system, therefore, determines, to a great extent, what applications you can run For PCs, the most popular operating systems are DOS, 0S/2, and Windows but others are available such as Linux.

四、阅读选择题(每小题2分,共20分)

1.

The Internet, then known as ARPANET, was brought online in 1969, which initially connected four major computers at universities in the southwestern US . The early Internet was used by

computer experts , engineers, scientists, and librarians. There was nothing friendly about it. There were no home or office personal computers in those days, and anyone who used it, whether a computer professional or an engineer or scientist or librarian, had to learn to use a very complex system.

The Internet matured in the 1970's as a result of the TCP/IP architecture. As the commands for E-mail, FTP , and telnet were standardized, it became a lot easier for non-technical people to learn to use the nets. It was not easy by today' s standards by any means, but it did open up use of the Internet to many more people in universities in particular. Other departments besides the libraries, computer, physics, and engineering departments found ways to make good use of the nets -- to communicate with colleagues around the world and to share files and resources.

In 1991, the first really friendly interface to the Internet was developed at the University of Minnesota. The University wanted to develop a simple menu system to access files and information on campus through their local network.

Since the Internet was initially funded by the government, it was originally limited to research, education, and government uses. Commercial uses were prohibited unless they directly served the goals of research and education. This policy continued until the early 1990's, when independent commercial networks began to grow.

Choose the best answer according to Passage.(根据上文的内容选择正确的答案。)

1. How many computers were connected to the initial Internet in 1969 ? ( B )

A. Ten

B. Four

C. Twenty

D. Three

2. Only ( A ) could use the early Internet.

A. computer experts, engineers, scientists, and librarians

B. any experts, engineers, scientists, and librarians

C. computer experts, engineers, scientists, and students

D. experts, engineers, and scientists in universities in US

3. The Internet became a lot easier for non-technical people to learn and use because of the common ( A )

A. commands

B. protocols

C. topologies

D. architecture

4. The first really friendly interface to the Internet appeared with the introduction of a ( C ) system for files and information access.

A. computer

B. operating

C. menu

D. application

5. Which statement is not true according to Passage C? ( D )

A. Many more people in universities began to use the Internet in the 1970s, but it wasn't as user-friendly as today's standards.

B. The restrictions to commercial uses changed as the independent commercial networks were not funded by the government.

C. Commercial uses were allowed for the early Internet if they directly served the goals of research and education.

D. The early Internet was logged in from home or office personal computers.

A computer virus is a computer program that is created to make and spread copies of itself. The program may however also be designed to have other effects on the systems it infects, ranging from the annoying to the disastrous.

Virus attacks are growing rapidly these days. According to Business Week, the 76,404 attacks reported in the first half of 2003 nearly match previous year's total number . As new antivirus tools are more powerful than before, the virus writers are getting a lot smarter with newer and creative ways to attack network systems. Let's first examine some common virus types:

Basic Virus - a piece of software code that is developed to attack computers and network systems via email or Internet connections. It quickly replicates itself and gradually attaches to files, programs or the hard drive.

Trojan Horses - This is a program that doesn't replicate when entering a system but can be effectively used to open 'back doors.' Trojan Horses allow hackers to take control over a particular system or to steal very important data.

Worm - this type of virus is able to spread itself automatically over the network from one computer to the next. During a worm attack, users' computers get infected without even having to click open email attachment or any program, etc.

Since it is very difficult to avoid the virus, your best defense is a powerful antivirus program. In order to fight with such viruses, the software vendors should focus on making their products more robust. This may ask for a trade-off between user-friendliness and security. In specific cases it may

require line-by-line inspection, code retooling and even systems automation to defend the installed programs.

6.A computer virus is a computer program that is created to make and spread ( C ) of itself.

A.programs B.virus C.copies D.files

7.Worm spread itself except by ( D ).

A.network B.E-mail C.program D.hardware

8.Antivirus program can scan and ( A ) virus.

A.clean B.produce C.replicate D.make

9.Trojan Horses ( C )

A.quickly replicate itself and gradually attached to files, programs or the hard drive.

B.infect the computer without even having to click open email attachment or any program. C.allow hackers to take control over a particular system or to steal very important data. D.avoid the virus to attack computer.

10.According to Business Week, the ( B ) attacks reported in the first half of 2003 nearly match previous year's total number .

A.86,404 B.76,404 C.56,354 D.34,876

五、阅读判断题(每小题2分,共10分)

A

During initial days of computing, software was largely developed by small groups of people. When this software was to be maintained by another set of people, it used to be a nightmarish experience. When large commercial projects were to be handled, it used to be an almost impossible task to keep the time and budget under control, and projects used to get delayed and many projects were abandoned halfway. There was no systematic procedure for the software development; everything was done on ad hoc basis. This ad hoc approach led to the ‘software crisis’.

Over the last few decades there has been a tremendous growth in information technology and its impact on everyday life. Complex software systems have become critical to the operation of many systems in areas such as banking, communications, manufacturing, power generation, and

transportation. Progress in computer science and accumulated experience with industrial production of software have led to the emergence of software engineering as a separate discipline. The software engineering discipline has been defined as "the application of systematic, disciplined, quantifiable approaches to the development, operation, and maintenance of software." that is, the application of engineering to software .

The computer science discipline concerns with developing large applications. Software engineering covers not only the technical aspects of building software systems, but also management issues, such as directing programming teams, scheduling, and budgeting.

For developing a software product, the development process is divided into different stages. A convenient way of splitting the whole process is to divide the development into the following five stages:

Requirements Analysis & Specification: define the system requirements in detail

Design: specify system architecture and modules in detail

Coding: produce source code

Testing: deal with unit testing and system testing

Maintenance: fix bugs, enhance features and adapt across platforms.

Tell whether the following statements are true(T) or false(F) according to the passage A.(根据上文的内容判断下列句子的正误)(10分,每题2分)

1. During initial days of the development of software, everything was done in discipline.

( F )

2. The definition of software engineering is "the application of systematic, disciplined, quantifiable approaches to the development, operation, and maintenance of software." ( T )

3. For developing a software product, you need design, coding and testing. ( T )

4. software engineering is the application of engineering to software . ( T )

5. Software engineering only covers the technical aspects of building software systems. ( F )

六、短文翻译题(共10分)

SQL Server is a RDBMS (Relational Database Management System) made by Microsoft. This means that the data is stored in two dimensional tables. RDBMS all have tables called catalogs or dictionaries that contain information about the particular databases. Don't worry if that doesn't make sense. I like to think of SQL Server as the big brother to Microsoft Access. SQL Server is designed to allow thousands of users to access the database at the same time and is a true

client/server database system. It is much more secure than Access. Rights can be assigned to individual users and administrators. For example you can setup one user that can only insert data in the database but cannot delete any.

SQLSever是微软的关系数据库管理系统。它的数据存储在二维表格中。关系数据库管理系统包含叫做目录或字典的表格,记录特定数据库的信息,如果不能理解也没关系。我喜欢将SQL Sever看作Access的哥哥。SQL Server允许数以千计的用户同时访问数据库,它是一个真正的C/S数据库系统,比Access更安全。权限可以分配给个人用户或管理者,比如,你可以建立一个用户,他能插入数据到数据库中,却不能删除数据。

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

Unit 8 Computer Networking Text 1 Data Communications The end equipment can be computers, printers, keyboards, CRTs, and so on.They are either generates the digital information for transmission or uses the received digital data. This equipment generally operates digital information internally in word units. DTE is data terminal equipment. A station controller (STACO)is the corresponding unit at the secondaries. At one time, the DTE was the last piece of equipment that belonged to the subscriber in a data link system. Between the DTEs, first is the modem, and then is the communications equipment. The communication equipment is owned and maintained by Telco. Data communications equipment (DCE) accepts the serial data stream from the DTE. And DCE converts it to some form of analog signal suitable for transmission on voice-grade lines. At the receive end, the DCE performs the reverse function. It converts the received analog signal to a serial digital data stream. The simplest form of DCE is a modem (modulator/demodulator) or data set. At the transmit end, the modem can be considered a form of digital-to-analog converter.While at the receive end, it can be considered a form of analog-to-digital converter. 参考译文 数据通信 终端设备可以是计算机、打印机、键盘、CRT等。它们可以生成要发送的数字信息,也可以使用所接收的数字数据。这种设备通常在内部以字为单位处理数字信息。 DTE一般称为数据终端设备。辅助设备一方的相应设备是工作站控制器(STACO)。同时,DTE也是数据链路系统中属于用户端的最后一个设备。在两个DTE之间,先是调制解调器,接着是属于Telco电话公司维护的通信设备。数据通信设备(DCE)从DTE接收串行数据流,并将其转换成适合于在语音线路上发送的某种模拟信号形式。在接收端,DCE完成相反的功能,把接收到的模拟信号转换成串行数字数据流。最简单的DCE是调制解调器或数据传送机。在发送端,调制解调器可以视为一种数/模转换器,而在接收端则可视为一种模/数转换器。 Text 2 Architecture of Computer Networks Computer network is a complex unit, it consists of two or more connected computing units. It is used for the purpose of data communication and resource sharing. Design of a network and its logical structure should comply with a set of design principles. They include: the organization of functions, the description of data formats and procedure. In the following two sections we will discuss two important network architectures, the OSI reference model and the TCP/IP reference model. (1)the OSI reference model The OSI (open systems interconnection) model was created by the ISO. This model is a foundation for comparing protocols; However, more protocols deviate from the rules set up by the OSI model. The OSI model has seven layers. Note that the OSI model itself is not a network architecture.

计算机英语_学生用书(第二版)姜同强_翻译

翻译:计算机英语(第二版)姜同强——第一章 第1 章计算机系统概述 数字计算机也称为电子计算机或计算机.它无处不在.很难发现有哪个领域没有使用计算机.在本章中.我们将介绍数字计算机、数据类型、计算机的发展和计算机分类, 1 . 1 数字计算机 数字计算机是处理各种计算任务的数字系统.“数字”的意思是计算机中的信息可由具有部分离散值的变量来表示,这些离散值的内部处理是由具有部分离散状态的部件完成的.例如.十进制数字O , l , 2 ,… 9 .即提供了10 个离散值。第一台电子数字计算机产生于20 世纪40年代末,它主要用于数值计算,那时的离散元素即为数字.为了进行数值计算而产生了数字计算机.实际上.如果只使用两种状态.数字计算机的性能将更可靠。因为部件的物理约束和人们的逻辑处理需要.所以数字计算机使用具有两种值的离散数据.这种数据称为二进制。 数字计算机使用只有数字O 和l 的二进制数据系统.一个二进制数字称作位.在数字计算机中用一组二进制表示信息。应用各种编码技术.一组二进制数字不但可以表示二进制数据,而且还可以表示其他离散符号.如十进制数字或字母表中的字母.例如ASCII是用7 位二进制数字表示一个字符。通过合理使用二进制组合和各种编码技术.可产生用于完成各种类型计算的一系列指令。与基数为10 的十进制数相比.二进制数的基数为2 .使用了数字O 和1 .与一个二进制数等值的十进制数可以扩展为包含更多位的二进制数. 计算机系统是由硬件系统和软件系统组成的,硬件系统由看得见、摸得着的物理设备构成.如磁盘和屏幕。软件系统是管理计算机的无形“控制”,是运行在计算机中的所有程序,程序是指令的集台,它告诉硬件应该做什么,通常将计算机硬件分为3 个主要部分:输入和输出设备(I/O 设备)、中央处理器(CPU)和存储器。在第2 章中对硬件部分进行详细介绍.软件可以按其用途分类。应用软件是为诸如会计、娱乐和工程领域之类的处理任务而设计的,如果玩过计算机游戏或用字处理软件输入入过文件内容.则用户已经具有使用应用软件的体验。另一方面.系统软件控制计算机系统,它不仅包括专业人员用于创建应用软件的复杂程序.而且还包括用于启动计算机和提供给其他程序使用的管理程序.这部分内容将在第2 章和第6 章中详细介绍, 1 . 2 数据类型 数字计算机中的二进制信息存储在存储器或处理器的寄存器中。寄存器的内容为数据或控制信息。控制信息为一位或多位.用于表明控制信号的顺序.这些信号用于处理其他寄存器的数据.数据是数字和其他二进制代码信息.通过处理这些数据得到所需的计算结果.下面介绍在数字计算机最常用的数据类型和各种数据类型在计算机的寄存器中如何以二进制代码的形式表示. 数字计算机寄存器中的数据可分类如下; .数值数据常用来表示整数.n位无符号整数.其值的表示范围为O ~-l ;n位带符号整数.其值的表示范围为- ~-1。这两种格式的数据可以用于算术运算。有些数值数据不能表示为整数。这些数值在计算机中用浮点格式表示.典型的如小数部分。计算机中有专用于浮点数的寄存器和指令。 .布尔值TRUE 和FALSE 经常被被使用.这使它们有自己的数据类型一一布尔型和汇编语言指令.常用0 值表示FALSE .用非0 值表示TRUE 。布尔汇编语言 指令可以对布尔数据执行逻辑操作。与逻辑指令每位都产生操作结果不同,布尔指令只产生一个结果。下面举例来说明它们的不同,若A=0000 0010 , B =0000 0001,则二进制数据的逻辑与运算的给果为0000 0000;然而,如果它们是布尔值,因为它们均为非O ,所以A 和B 均为TRUE ,对它们进行布尔与运算给果为TRUE ,用非O 值表示。 .计算机也可处理字符型数据。字符型数据用ASCII、EBCDIC 、UNICODE或其他字符编码标准编码后的二进制数据进行存储。计算机能将若干字符连成串,用一些字符代替其他字符或另行处理字符串,而不是用算术方法或逻辑方法处理字符。有些汇编语言指令集中包含了直接处理字符数据的指令,而另一些汇编语言指令集中则运用其他指令构成例程来达到相同的结果。 1.3 计算机的发展 第一台大型电子计算机是电子数字模拟计算机(ENIAC),它诞生于1946 年.从此计算机经历了4 个发展年代或阶段。每一年代的特点是:与上一年代相比,体积更小,费用更低。 1 .第一代(1944-1958)
