III. Fill in each of the blanks with one of the words given in the following list, making changes if necessary: We can define a computer as a device that accepts input, processes data, stores data, and produces output. According to the mode of processing, computers are either analog or digital. They can also be classified as mainframes, minicomputers, workstations, or microcomputers. All else (for example, the age of the machine) being equal, this categorization provides some indication of the computer’s speed, size, cost, and abilities.

Ever since the advent of computers, there have been constant changes. First-generation computers of historic significance, such as UNIVAC (通用自动计算机), introduced in the early 1950s, were based on vacuum tubes. Second-generation computers, appearing in the early 1960s, were those in which transistors replaced vacuum tubes. In third-generation computers, dating from the 1960s, integrated circuits replaced transistors. In fourth-generation computers such as microcomputers, which first appeared in the mid-1970s, large-scale integration enabled thousands of circuits to be incorporated on one chip. Fifth-generation computers are expected to combine very-large-scale integration with sophisticated approaches to computing, including artificial intelligence and true distributed processing.

IV. Translate the following passage from English into Chinese:

计算机将变得更加先进，也将变得更加容易使用。语音识别的改进将使计算机的操作更加容易。虚拟现实，即使用所

有人类官能与计算机进行交互的技术，也将有助于创建更好的人机接口。人们正在开发其他的奇异计算模型，包括使用生物机体的生物计算、使用具有特定属性的分子的分子计算，以及使用遗传基本单位DNA（脱氧核糖核酸）存储数据和执行操作的计算。这些都是可能的未来计算平台的例子，而它们迄今还能力有限或完全属于理论范畴。科学家们研究它们，是因为嵌入硅中的电路的微小型化受到物理限制。还有一些限制与甚至最微小的晶体管也会产生的热量有关。

20. 视频显示器video display

III. Fill in each of the blanks with one of the words given in the following list, making changes if necessary: CD-ROM stands for compact disc read-only memory. Unlike floppy and hard disks, which use magnetic charges to represent 1s and 0s, optical discs use reflected light. On a CD-ROM disc, 1s and 0s are represented by flat areas and bumpy (高低不平的) areas (called “pits”) on its bottom surface. The CD-ROM disc is read by a laser that projects a tiny beam of light on these areas. The amount of reflected light determines whether the area represents a 1 or a 0.

Like a commercial CD found in music stores, a CD-ROM is a “read-only” disc. Read-only means it cannot be written on or erased by the user. Thus, you as a user have access only to the data imprinted (压印) by the publisher.

A single CD-ROM disc can store 650 megabyte s (兆字节) of data. That is equivalent to 451 floppy disks. With that much information on a single disc, the time to retrieve or access the information is very important. An important characteristic of CD-ROM drives is their access rate.

IV. Translate the following passage from English into Chinese:

调制解调器是在模拟和数字信号之间进行转换的设备。计算机使用的是数字信号，这种信号由离散单元组成，通常用一系列1和0表示。模拟信号是连续变化的；声波就是模拟信号的一个例子。调制解调器经常用于实现计算机之间通过电话线的互相通信。调制解调器将发送端计算机的数字信号转换成可通过电话线传输的模拟信号。信号到达目的地后，另外一个调制解调器重构原来的数字信号，供接收端计算机处理。如果两个调制解调器可同时互相发送数据，那么它们采用的就是全双工工作方式；如果一次只有一个调制解调器可以发送数据，那么它们采用的则是半双工工作方式。

20. 计算机程序员computer programmer

III. Fill in each of the blanks with one of the words given in the following list, making changes if necessary:

A programming language is a language used to write instructions for the computer. It lets the programmer express data processing in a symbolic manner without regard to machine-specific details.

The difficulty of writing programs in the machine language of 0s and 1s led first to the development of assembly language, which allows programmers to use mnemonics (助记符) for instructions and symbols for variables. Such programs are then translated by a program known as an assembler into the binary encoding used by the computer. Other pieces of system software known as linking loaders (连接装入程序) combine pieces of assembled code and load them into the machine’s main memory unit, where they are then ready for execution. The concept of linking separate pieces of code was important, since it allowed “libraries” of programs to be built up to carry out common tasks—a first step toward the increasingly emphasized notion of software reuse. Assembly language was found to be sufficiently inconvenient that higher-level languages (closer to natural languages) were

invented in the 1950s for easier, faster programming; along with them came the need for compilers, programs that translate high-level language programs into machine code. As programming languages became more powerful and abstract, building efficient compilers that create high-quality code in terms of execution speed and storage consumption became an interesting computer science problem in itself.

IV. Translate the following passage from English into Chinese:

面向对象程序设计语言，如C++和Java，基于传统的高级语言，但它们使程序设计员能够从合作对象集而非命令列表的角度进行思考。诸如圆之类的对象具有像圆的半径一类的属性，以及在计算机屏幕上绘制该对象的命令。一个对象类可以从其他的对象类继承特征。例如，定义正方形的类可以从定义长方形的类那里继承直角等特征。这一套程序设计类简化了程序设计员的工作，带来了更多“可复用的”计算机代码。可复用代码使程序设计员可以使用已经设计、编写和测试的代码。这使得程序设计员的工作变得比较容易，并带来更加可靠和高效的程序。

Unit Four: Software Development

18. 逻辑程序logic program

19. 墨盒ink cartridge

20. 程序的存储与执行program storage and execution

III. Fill in each of the blanks with one of the words given in the following list, making changes if necessary:

A compiler, in computer science, is a computer program that translates source code into object code. Software engineers write source code using high-level programming languages that people can understand. Computers cannot directly execute source code, but need a compiler to translate these instructions into a low-level language called machine code.

Compilers collect and reorganize (compile) all the instructions in a given set of source code to produce object code. Object

code is often the same as or similar to a computer’s machine code. If the object code is the same as the machine language, the computer can run the program immediately after the compiler produces its translation. If the object code is not in machine language, other programs—such as assemblers, binders (联编程序), linkers, and loaders (加载程序)—finish the translation.

Most computer languages use different versions of compilers for different types of computers or operating systems, so one language may have different compilers for personal computers (PC) and Apple Macintosh computers. Many different manufacturers often produce versions of the same programming language, so compilers for a language may vary between manufacturers.

IV. Translate the following passage from English into Chinese:

在软件中，错误是指导致程序发生故障或产生不正确结果的编码或逻辑错误。较轻微的错误，如光标表现异常，会造成不便或带来挫折，但不会对信息产生破坏性影响。较严重的错误会导致程序“中止”（对命令停止反应），可能使用户别无选择，只能重新启动程序，结果致使任何前面已经做好但尚未保存的工作丢失。两种情况无论是哪一种，程序员都必须凭借称为调试的过程，发现并改正错误。由于错误对重要数据的潜在危险，商用应用程序在发行前要经过尽可能全面的测试与调试。程序发行后发现的较轻微错误

在下一次更新时改正；较严重的错误有时可用称为补丁的特殊软件加以修补，以规避问题或减轻其影响。

19. 软件维护工具software maintenance tool

20. 软件复用software reuse

III. Fill in each of the blanks with one of the words given in the following list, making changes if necessary: There are three different types of software maintenance. Firstly, there is maintenance to repair software faults. Coding errors

are usually relatively cheap to correct; design errors are more expensive as they may involve rewriting several program components. Requirements errors are the most expensive to repair because of the extensive system redesign that may be necessary. Secondly, there is maintenance to adapt the software to a different operating environment. This type of maintenance is required when some aspect of the system’s environment such as the hardware, the platform operating system or other support software changes. The application system must be modified to adapt it to cope with these environmental changes. And thirdly, there is maintenance to add to or modify the system’s functionality.

This type of maintenance is necessary when the system requirements change in response to organizational or business change. The scale of the changes required to the software is often much greater than for the other types of maintenance. In practice, there isn’t a clear-cut distinction between these types of maintenance. When you adapt the system to a new environment, you may add functionality to take advantage of new environmental features.

Software faults are often exposed because users use the system in unanticipated ways. Changing the system to accommodate their way of working is the best way to fix these faults.

IV. Translate the following passage from English into Chinese:

软件过程比较复杂，而且像所有其他的智能和创造性过程一样，依靠人们作出决定和判断。由于需要判断和创造性，使软件过程自动化的尝试只取得了有限的成功。计算机辅助软件工程工具可支持软件过程的某些活动。然而，至少是在未来几年内，不可能实现更广泛的软件过程自动化，使软件能够接替参与软件过程的工程师来从事创造性设计。

计算机辅助软件工程工具的有效性有限，原因之一是软件过程多种多样。不存在理想的过程，而且许多组织机构发展了自己的软件开发方法。这些软件过程不断演变，以利用组织机构中的人员的能力和开发中的系统的具体特点。对于一些系统来说，需要的是一个高度结构化的开发过程，而对于另外一些系统来说，一个灵活敏捷的过程很可能更为有效。

20. 全局控制总线global control bus

III. Fill in each of the blanks with one of the words given in the following list, making changes if necessary:

A database is any collection of data organized for storage in a computer memory and designed for easy access by authorized users. The data may be in the form of text, numbers, or encoded graphics. Small databases were first developed or funded by the U.S. government for agency or professional use. In the 1960s, some databases became commercially available, but their use was funnelled (传送) through a few so-called research centers that collected information inquiries and handled them in batches. Online databases—that is, databases available to anyone who could link up to them by computer—first appeared in the 1970s.

Since their first, experimental appearance in the 1950s, databases have become so important that they can be found in almost every field of information. Government, military, and industrial databases are often highly restricted, and professional databases are usually of limited interest. A wide range of commercial, governmental, and nonprofit databases are available to the general public, however, and may be used by anyone who owns or has access to the equipment that they require.

IV. Translate the following passage from English into Chinese:

在关系数据库中，表的行表示记录（关于不同项的信息集），列表示字段（一个记录的特定属性）。在进行搜索时，关系数据库将一个表中的一个字段的信息与另一个表中的一个相应字段的信息进行匹配，以生成将来自这两个表的所要求数据结合起来的另一个表。例如，如果一个表包含EMPLOYEE-ID 、LAST-NAME、FIRST-NAME和HIRE-DATE字段，另一个表包含DEPT、EMPLOYEE-ID和SALARY字段，关系数据库可匹配这两个表中的EMPLOYEE-ID字段，以找到特定的信息，如所有挣到一定薪水的雇员的姓名或所有在某个日期之后受雇的雇员所属的部门。换言之，关系数据库使用两个表中的匹配值，将一个表中的信息与另一个表中的信息联系起来。微型计算机数据库产品一般是关系数据库。

19. 无绳电话cordless telephone

20. 金属导体metal conductor

III. Fill in each of the blanks with one of the words given in the following list, making changes if necessary: Data communications is the process of transmitting and receiving data in an orderly way so the data that arrives at its destination is an accurate duplication (复制) of the data that was sent. When data travels a short distance, such as when you send data from your computer to your printer, it is referred to as local communications. When data travels a long distance, the communication is referred to as telecommunications; the prefix (前缀) “tele” is derived from a Greek word that means “far” or “far off.”

The difference between a short distance and a long distance is somewhat arbitrary (武断的). For example, if your computer sends data to a printer in the next room, it is regarded as local communications; if you phone the person in the next room, you are transmitting data over a telecommunications device. However, the same basic communications concepts apply to both local communications and telecommunications.

Basic data communications concepts are the building blocks for understanding how data travels on a communications system. These concepts come in handy (派得上用处) when you install, configure, or upgrade a local area network. In addition, these concepts help you set up modems, fax machines, and cellular data transfers.

IV. Translate the following passage from English into Chinese:

个人计算机使用电信来提供传输链路，用于传送音频、视频、文本、软件和多媒体服务。许多专家认为，这些服务的结合将带来用户对新一代高速、宽带网络的需求。当前，这些音频、视频和文本服务大多通过现有的电话连接使用因特网传送。有些计算机使用综合业务数字网或数字用户线路直接连接到电话网的数字部分，但这要求在用户处有专门的设备。此外，电话及有线电视公司还必须对其线路进行升级，以使其能够进行高速数据传输。在许多地点，有高速数据传输需求的公司和个人现在可选择从电话公司得到数字用户线路服务，从有线电视公司得到光缆调制解调器服务。

20. 广域网wide area network (WAN)

III. Fill in each of the blanks with one of the words given in the following list, making changes if necessary: Computers can communicate with other computers through a series of connections and associated hardware called a network. The advantage of a network is that data can be exchanged rapidly, and software and hardware resources, such as hard-disk space or printers, can be shared. Networks also allow remote use of a computer by a user who cannot physically access the computer.

One type of network, a local area network (LAN), consists of several PCs or workstations connected to a special computer called a server, often within the same building or office complex. The server stores and manages programs and data. A server often contains all of a networked group’s data and enables LAN workstations or PCs to be set up without large storage capabilities. In this scenario (方案), each PC may have “local” memory (for example, a hard drive) specific to itself, but the bulk of storage resides on the server. This reduces the cost of the workstation or PC because less expensive computers can be purchased, and it simplifies the maintenance of software because the software resides only on the server rather than on each individual workstation or PC.

IV. Translate the following passage from English into Chinese:

在计算机科学中，网络是指由通信设备连接在一起的一组计算机及其相关设备。网络可采用电缆等永久性连接，或者采用通过电话或其他通信链路而实现的临时性连接。网络可以小到由少数计算机、打印机以及其他设备构成的局域网，也可以由分布在广大地理区域的许多小型与大型计算机组成。计算机网络无论大小，其存在的目的均在于为计算机用户提供以电子方式进行信息通信与传送的方法。有些类型的通信是简单的用户到用户消息；有些称为分布式过程，可能涉及数台计算机，以及在执行任务中分担工作量或进行协作。

19. 主机地址host address

20. 硬件与软件支持hardware and software support

III. Fill in each of the blanks with one of the words given in the following list, making changes if necessary: Early computer networks used leased telephone company lines for their connections. Telephone company systems of that time established a single connection between sender and receiver for each telephone call, and that connection carried all data along a single path. When a company wanted to connect computers it owned at two different locations, the company placed a telephone call to establish the connection, and then connected one computer to each end of that single connection.

The U. S. Defense Department was concerned about the inherent risk of this single-channel method for connecting computers, and its researchers developed a different method of sending information through multiple channels. In this method, files and messages are broken into packets that are labeled electronically with codes for their origins, sequences, and destinations. In 1969, Defense Department researchers in the Advanced Research Projects Agency (ARPA) used this network model to connect four computers into a network called the ARPANET. The ARPANET was the earliest of the networks that eventually combined to become what we now call the Internet. Throughout the 1970s and 1980s, many researchers in the academic community connected to the ARPANET and contributed to the technological developments that increased its speed and efficiency.

IV. Translate the following passage from English into Chinese:

因特网只是提供了将许许多多的计算机连接在一起的物理与逻辑基础结构。不少人认为，是万维网（WWW或简称the Web）为这个全球网络提供了“制胜法宝”。万维网被视为因特网的内容，它通过使用管理与链接文本、图形、声音和视频的一套丰富工具来提供各种信息。在万维网上提供和查看信息，是使用服务器应用程序和客户应用程序完成的。

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.
