1.1A Closer Look at the Processor and PrimaryStorage仔细看看处理器和主存储器We have learned that all computers have similar capabilities and perform essentially the same functions, although some might be faster than others. We have also learned that a computer system has input, output, storage, and processing components; that the processor is the “intelligence” of a computer system; and that a single computer system may have several processors. We have discussed how data are represented inside a computer system in electronic states called bits. We are now ready to expose the inner workings of the nucleus of the computer system — the processor.我们已经知道,所有的计算机都具有相似的能力,并且在本质上执行相同的功能,尽管一些可能会比另一些快一点。
我们也知道,一个计算机系统具有输入,输出,存储和处理部件;处理器是一个计算机系统智能核心,并且一个计算机系统可以有许多个处理器。
我们已经讨论过如何在计算机系统内部,用被称作“位”的电子状态来表现数据,现在我们要弄明白计算机系统的核心,即处理器,的内在的工作方式。
COMMUNICATION CHANNELSCommunication channels are an essential element of every communication system. These channels actually carry the data from one computer to another. There are two categories of communication channels. One category connects sending and receiving devices by providing a physical connection such as a wire or cable. The other category is wireless.沟通渠道是一个至关重要的元素的每个通信系统。
这些渠道实际上把数据从一台计算机到另一个。
有两个类别的沟通渠道。
一个类别连接发送和接收设备通过提供一个物理连接导线或电缆等。
另一类是无线。
PHYSICAL CONNECTIONSPhysical connections use a solid medium to connect sending and receiving devices. These connections include telephone lines (twisted pair), coaxial cable,and fiber-optic cable.物理连接使用固体介质连接发送和接收设备。
这些连接包括电话线路(双绞线)、同轴电缆和光纤电缆。
Telephone lines you see strung on poles consist of twisted-pair cable,which is made up of hundreds of copper wires. A single twisted pair culminates in a wall jack into which you can plug your phone and computer. (See Figure 9-3.) Telephone lines have been the standard transmission medium for years for both voice and data. However, they are now being phased out by more technically advanced and reliable media.Coaxial cable, a high-frequency transmission cable, replaces the multiple wires of telephone lines with a single solid-copper core. (See Figure 9-4.) In terms of the number of telephone connections, a coaxial cable has over 80 times the transmission capacity of twisted pair.Coaxial cable is used to deliver television signals as well as to connect computers in a network..电话线路你看到两极串在由双绞线,是由数以百计的铜线。
Unit 10 Program DesignText 1 Computer LanguagesComputer languages have undergone dramatic evolution since the first electronic computers were built. Early on, programmers worked with the most primitive computer instructions—machine language. These instructions were represented by long strings of ones and zeroes. Soon, assembly language was invented. It maps machine instructions to human-readable mnemonics, such as ADD and MOV.In time, higher-level languages evolved, such as PASCAL, BASIC, COBOL, C, C++, and JA V A. These languages let people work with something approximating words and sentences, such as Let I = 100. These instructions were translated back into machine language by interpreters and compilers. An interpreter translates a program as it reads it, turning the program instructions, or code, directly into actions. A compiler translates the code into an intermediary form. This step is called compiling, and produces an object file. The compiler then invokes a linker, which turns the object file into an executable program.Because interpreters read the code as it is written and execute the code on the spot, interpreters are easy for the programmer to work with. Compilers, however, introduce the extra steps of compiling and linking the code, which is inconvenient. Because the time-consuming task of translating the source code into machine language has already been accomplished, compilers produce a program that is very fast each time it is run.The problems programmers are asked to solve have been changing. Today's programs use sophisticated "user-friendly interfaces," involving multiple windows, menus, and dialog boxes. The programs written to support this new approach are far more complex than those written just ten years ago. Generally, as programming requirements have changed, both languages and the techniques used for writing programs have evolved.参考译文计算机语言自从第一批电子计算机诞生以来,计算机语言已经发生了戏剧性的变化。

第5单元程序开发和编程语言第一部分听力和对话对话:认识Java运行时环境(JRE)和Java虚拟机(JVM)(在Java编程的第一课之前,Mark下载了一个简单的Java小应用程序进行示例学习,但他发现,它无法正常运行。
)Mark:对不起,Henry和Sophie。
你们能帮助我吗?Henry:当然可以。
什么问题?Mark:为什么这个Java小应用程序不能运行?它的源代码是正确的。
Sophie:你的计算机是否安装了Java运行环境[1]?Mark:还没有。
什么是Java运行环境?Henry:简称JRE,是一个由太阳微系统公司开发的软件平台,可以让计算机运行由Java 编程语言编写的Java小应用程序和应用程序。
[2]Sophie:它包含Java虚拟机、Java库和一些其他组件。
Mark:Java虚拟机是做什么用的?Sophie: Java虚拟机(简称JVM)是一套计算机软件程序和数据结构,它使用虚拟机模型来执行其他计算机程序和脚本。
它可以隐藏能够运行程序的计算机硬件的细节。
[3]Mark:JVM和JRE是什么关系?[4]Henry:JVM是JRE的实例,当执行Java程序时开始起作用。
当执行完成后,这个实例具有垃圾回收机制。
JVM与一套能够实现Java API(Application Program Interface,应用程序接口)的标准类库一起发行。
虚拟机和API必须彼此一致,因此它们被捆绑成为JRE.[5]Sophie:因此,这可以被视为一个虚拟的计算机,其中虚拟机是处理器,并且API是用户界面。
Henry: JVM是Java平台一个至关重要的组件。
使用所有平台的相同字节码可将Java描述成“编译一次,到处运行”Mark: 字节码?Henry:是的。
JVM在通常称为Java字节码的一种中间语言上运行,这种中间语言通常是由Java源代码产生的,但也不一定。
打算在JVM上运行的程序,必须编译成这种标准化的可移植的二进制格式。
计算机专业英语翻译参考1.(P1) Computer science deals with the theoreticalfoundations of information and computation, together with practical techniques for the implementation and application of these foundations, such as programming language theory, computational complexity theory, computer graphics and human-computer interaction.计算机科学涉及信息和计算的理论基础,以及这些基础的实施和应用的实际技术,如编程语言理论,计算复杂性理论,计算机图形学和人机交互。
2.(P17) The most important piece of graphics hardware isthe graphics card, which is the piece of equipment that renders out all images and sends them to a display.There are two types of graphics cards: integrated and dedicated. An integrated graphics card, usually by Intel for use in their computers, is bound to the motherboard and shares RAM (Random Access Memory) with the CPU, reducing the total amount of RAM available. This is undesirable for running programs and applications that use a large amount of video memory. A dedicated graphics card has its own RAM and Processor for generating its images, and does not slow down the computer. Dedicated graphics cards also have higher performance than integrated graphicscards. It is possible to have both dedicated and integrated graphics card, however once a dedicated graphics card is installed, the integrated card will no longer function until the dedicated card is removed.最重要的一块图形硬件是显卡,是一件呈现出所有的图像,并将它们发送到一个显示器的设备。

中译英参考答案Unit 1A computer system consists of hardware system and software system. The hardware of the computer is usually divided into three major parts or three primary subsystems: the CPU, the memory subsystem, and the I/O subsystem.The CPU performs many operations and controls computer. The memory subsystem is used to store program being executed by the CPU, along with the program’s data. The I/O subsystem allows the CPU to interact with input and output devices such as the keyboard and monitor of a personal computer. The components of the computer are connected to the buses.The part of the computer that performs the bulk of data processing operations is called the central processing unit and is referred to as the CPU. In microcomputer, it is often called the microprocessor. The CPU is made up of three major parts: control unit, ALU, and register set.Memory is also known as internal memory or main memory. It refers to the circuits in the computer that hold whatever programs and data are available for immediate use by the CPU.I/O subsystem includes I/O devices and interface. There are a wide variety of I/O devices, such as mouse, printer, sensor, disk, and so on. Input-output interface provides a method for transferring information between internal storage and external I/O devices. Peripherals connected to a computer need special communication links for interfacing them with the CPU. The purpose of the communication link is to resolve the differences that exist between the central computer and each peripheral.Unit 2Storage hardware provides permanent storage of information and programs for retrieval by the computer. Hard disk drives store information in magnetic particles embedded in a disk. Usually a permanent part of the computer, hard disk drives can store large amounts of information and retrieve that information very quickly.Although fixed hard drive systems offer faster access and have a higher storage capacity than optical discs, optical disc systems use removable media – a distinct benefit. Optical discs – primary CDs and DVDs – are much more widely used than removable hard drive systems. They are the standard today for software delivery, as well as commonly used for storing high-capacity music and video files. There are also versions of both CD and DVD drives available for home audio and home theater use. Optical discs are commonly referred to as compact discs.CD and DVD discs are read by CD and DVD drives. The speed of a CD or DVD drive is rated as 24x, 32x, 36x, and so on. These labels describe how fast the drive is compared to the first version of that drive. For example, a 36x drive is 36 times the speed of the baseline unit that was originally manufactured.Most optical discs have a title and other text printed only on one side and they are inserted into the drive with the printed side facing up. When inserting such a CD or DVD, be careful not to get dirt, fingerprints, scratches, or anything else that might hinder light reflectivity on the disc’s surface.Unit 3(a) A program is a list of instructions or statements for directing the computer to perform a required data processing task. Programming is a multistep process for creating that list of instructions.(b) It is important to understand the difference between a class and an object of that class. A class is simply a specification for creating objects. Thus, a single class may create multiple objects.(c) Java is an object-oriented, network-friendly high-lever programming language that allows programmers to build applications that can run on almost any operating system.(d) ActiveX is a set of controls, or reusable components that enables programs or content of almost any type to be embedded within a Web page. Whereas a Java must be downloaded each time you visit a Web site, with ActiveX the component is downloaded only once, then stored on your hard disk for later, repeated use.(e) Programming involves a great deal of creativity. The design is guide to the function or purpose of each component, but the programmer has great flexibility in implementing the design as code. No matter what language is used, each program component involves at least three major aspects: control structures, algorithms, and data structures.Unit 4The software system can be divided into two broad categories: application software and system software. Application software consists of the program for performing tasks particular to the machine’s utilization. In contrast to application software, system software comprises a large number of programs. These programs start up the computer and function as the principle coordinator of all hardware components and application software. Without system software loaded into RAM of your computer, your hardware and application software are useless.System software can be grouped into three basic parts: operating system, utility software, and language translators. The majority of an installation’s utility software consists of programs for performing activities that are fundamental to computer installations yet not included in the operating system. In a sense, utility software consists of software units that extend the capabilities of the operating system.A computer’s OS is the main collection of programs that manage its activities.The primary chores of an OS are management and control. The OS ensures that all actions requested by a user are valid and processed in an orderly fashion. It also manages the computer system’s resources to perform these operations with efficiency and consistency.Application software is the software designed to help you solve problems specific to business or perform specific business tasks. Application software then is the layer of software closest to you. Basically, there are four categories of application software: productivity software, business and specialty software, entertainment software and education/reference software.Unit 5A computer network is often classified as being either a local area network (LAN), a metropolitan area network (WAN), or a wide area network (WAN). The connection of two or more networks is called an internetwork. The worldwide Internet is a well-known example of an internetwork.LANs are privately owned networks within a single building or campus of up to a few kilometers in size. They are widely used to connect personal computers and workstations in company offices and factories to share resources and exchange information.In general, a given LAN will use only one type of transmission medium. Various topologies are possible for LANs. The most common LAN topologies are bus, ring and star.A MAN is basically a bigger version of a LAN and normally uses similar technology. MAN is designed to extend over an entire city. It may be a single network such as a cable television network, or it may be a means of connecting a number of LANs into a large network so that resources may be shared LAN-to-LAN as well as device-to-device. For example, a company can use a MAN to connect the LANs in all of its offices throughout a city.A W AN spans a large geographical area that may comprise a country, a continent, or even the world. It provides long-distance transmission of data, voice, image, and video information over large geographical area.In contrast to LANs, W ANs may utilize public leased, or private communication devices, usually in combinations, and can therefore span an unlimited number of miles.Unit 6Transmission media are used to transfer messages over a network. For instance, the transmission media used in a network may be a privately owned set of cables, the public phone lines, or a satellite system. Transmission media can either be wired or wireless.The three types of wired media most commonly used to carry messages are twisted-pair wire, coaxial cable, and fiber-optic cable. One of the most successful developments in transmission media in recent years has been fiber optics. Fiber-optic cable is commonly used for the high-speed backbone lines of a network, or for Internet infrastructure.Wireless transmission media have become especially popular in recent years. They support communications in situations in which physical wiring is impractical or inconvenient, as well as facilitate mobility. Wireless media are commonly used to connect devices to a network, to share information between computers, to connect wireless mice to a computer, and for handheld PCs, wireless phones, and other mobile devices. Radio signals transferred through the air are the heart of most types of wireless media. In addition to conventional broadcast radio application, the microwave, cellular, and satellite transmission media also use radio signals to transmit data.Radio transmissions require the use of a transmitter to send the radio signals through the air. A receiver (usually containing some type of antenna) accepts the date at the other end. When a device functions as both a receiver and transmitter, it is commonly called a transceiver or transmitter-receiver.Unit 7(a) Since many database systems users are not computer trained, developers hide the complexity from users through several levels of abstraction, to simplify user’s interactions with the system: physical level, logical level, and view level.(b) A database schema is specified by a set of definitions expressed by a special language called a data-definition language (DDL). The result of compilation of DDL statements is a set of tables that is stored in a special file called data dictionary, or data directory.(c) The structured query language (SQL) is the most widely used and standard query language for relational database management systems. It is a kind of non-procedural language.(d) An entity is a “thing” or “object” in the real world that is distinguishable from other objects. For example, each person is an entity, and bank accounts can be considered to be entities. Entities are described in a database by a set of attributes.(e) Data warehouse is one of the newest and hottest buzzwords and concepts in the IT field and the business environment. A data warehouse is a logical collection of information——gathered from many different operational databases——that supports business analysis activities and decision-making tasks.Unit 8Animation is the term used to describe a series of graphical images that are displayed one after the other to simulate movement. Cartoons on television are one example of animation.Video differs from animation in that it usually begins as a continuous stream of visual information that is broken into separate images or frames when the video is recorded. When the frames are projected—typically at a rate of 30 frames per second—the effect is a smooth reconstruction of the original continuous stream of information. As you might imagine, at 30 frames per second, the amount of data involved in displaying a video during a multimedia presentation can require a substantial amount of storage space. Consequently, video data—like audio data—is often compressed. A variety of compression standards exist. Some of the most common video file formats are .avi, .mpeg, .mov, .rm.For multimedia presentation, video may be recorded using a standard (analog) video camera and then converted to digital form as it is input into a computer. Alternatively, the film can be recording digitally using a digital video camera. Streaming video is frequently used on Web pages to reduce file size. Similar to streaming audio, Streaming video files can begin playing once a portion of the video has been downloaded.Unit 9(a) AI is currently being applied in business in the form of knowledge systems, which use human knowledge to solve problems. The most popular type of knowledge-based system is the expert system. An expert system is a computer program that attempts to represent the knowledge of human experts in the form of heuristics. The term heuristic is derived from the same Greek root as the word eureka, which means “to discover”.(b) The user interface enables the manager to enter instructions and information into the expert system and to receive information from it. The instructions specify the parameters that guide the expert system through its reasoning processing. The information is in the form of values assigned to certain variables.(c) The knowledge base contains both facts that describe the problem area and knowledge representation techniques that describe how the facts fit together in a logical manner. The term problem domain is used to describe the problem area.(d) An expert system, also called a knowledge-based system, is an artificial intelligence system that applies reasoning capabilities to reach a conclusion. Expert systems are excellent for diagnostic and prescriptive problems.(e) The DSS is not intended to replace the manager. The computer can be applied to the structured portion of the problem, but the manager is responsible for the unstructured portion——applying judgment or intuition and conducting analyses.Unit 10The linked list (see figure 1) consists of a series of nodes, which are not necessarily adjacent in memory. Each node contains the element and a link to a node containing its successor. We call this the next link. The last cell’s next link references null.To execute printList or find(x) we merely start at the first node in the list and then traverse the list by following the next links. This operation is clearly linear-time, as in the array implementation, although the constant is likely to be larger than if an array implementation were used. The findKth operation is no longer quite as efficient as an array implementation; findKth(i) takes O(i) time and works by traversing down the list in the obvious manner. In practice, this bound is pessimistic, because frequently the calls to findKth are in sorted order (by i). As an example, findKth(2), findKth(3), findKth(4), and findKth(6) can all be executed in one scan down the list.The remove method can be executed in one next reference change. Figure 2 shows the result of deleting the second element in the original list.The insert method requires obtaining a new node from the system by using a new call and then executing two reference maneuvers. The general idea is shown in figure 3. The dashed line represents the old next reference.Unit 11(a) A set is pure if all of its members are sets, all members of its members are sets, and so on. For example, the set containing only the empty set is a nonempty pure set.(b) A language is a describable set of finite strings, drawn from a fixed alphabet. A grammar is one way to "describe" the language. The grammar consists of a finite list of rules, where each rule replaces one substring with another. The string on the left must contain at least one nonterminal. The first string "produces" or "generates" the second. Thus a rule is also called a production.(c) A finite-state machine (FSM) or finite-state automaton(FA)is a mathematical abstraction sometimes used to design digital logic or computer programs. It is a behavior model composed of a finite number of states, transitions between those states, and actions, similar to a flow graph in which one can inspect the way logic runs when certain conditions are met.(d) Sometimes it is inconvenient or impossible to describe a set by listing all of its elements. Another useful way to define a set is by specifying a property that the elements of the set have in common. The notation P(x) is used to denote a sentence or statementP concerning the variable object x. The set defined by P(x) written {x | P(x)}, is just a collection of all the objects for which P is true.Unit 12(a) Because drawings are typically displayed in 3D, CAD is especially helpful in designing automobiles, aircraft, ships, buildings, electrical circuits (including computer chips), and even clothing.(b) Computer-integrated manufacturing (CIM) is the manufacturing approach of using computers to control the entire production process. This integration allows individual processes to exchange information with each other and initiate actions. Through the integration of computers, manufacturing can be faster and less error-prone, although the main advantage is the ability to create automated manufacturing processes.(c) In addition to supporting decision making, coordination, and control, information system may also help managers and workers analyze problems, visualize complex subjects, and create new products.(d) Knowing the history and evolution of ERP is essential to understanding its current application and its future developments.(e) In addition to monitoring operational activities such as tracking the status of orders and inventory levels, enterprise system also improve organization-wide reporting and decision making.Unit 13(a) There are a wide variety of educational application programs available. Educational software is designed to teach one or more skills, such as reading, math, spelling, a foreign language, world geography, or to help prepare for standardized tests.(b) Electronic business (e-business) is the use of information technology and electronic communication networks to exchange business information and conduct transactions in electronic, paperless form.(c) Word processing software allows you to use computers to create, edit, store, and print documents. You can easily insert, delete, and move words, sentences, and paragraphs——without ever using an eraser.(d) What is a spreadsheet? Spreadsheet software takes its name from the accountant’s columnar worksheet, which it imitates. A spreadsheet is a worksheet consisting of a collection of cells formed by the intersection of rows and columns. Each cell can store one piece of information: a number, word or phrase, or formula.Unit 14(a) A geographic information system (GIS) is a system that captures, stores, analyzes, manages and presents data with reference to geographic location data. In the simplest terms, GIS is the merging of cartography, statistical analysis and database technology.(b) The GPS receiver uses the messages it receives to determine the transit time of each message and computes the distance to each satellite. These distances along with the satellites' locations are used to compute the position of the receiver. This position is then displayed, perhaps with a moving map display or latitude and longitude; elevation information may be included.(c) Virtual reality (VR) is a term that applies to computer-simulated environments that can simulate physical presence in the real world. Most current virtual reality environments are primarily visual experiences, displayed either on a computer screen or through special stereoscopic displays, but some simulations include additional sensory information, such as sound through speakers or headphones.Unit 15(a) The software development process is sometimes called the software development life cycle (SDLC), because it describes the life of a software product from its conception to its implementation, delivery, use, and maintenance.(b) How can the CMM help your organization? There are three key roles the CMM plays. First, the CMM helps build an understanding of software process by describing the practices that contribute to a level of process maturity. The second role of the CMM is to provide a consistent basis for conducting appraisals of software processes. The CMM’s third key role is to serve as a blueprint for software process improvement.(c) The UML offers a standard way to write a system’s blueprints, including conceptual things such as business processes and system functions as well as concrete things such as programming language statements, database schemas, and reusable software components. The UML represents a collection of the best engineering practices that have proven successful in the modeling of large and complex systems.(d) Object modeling is a technique for identifying objects within the system environment and the relationships between those objects. The object-oriented approach to system development is based on several concepts, such as object, attribute, behavior, encapsulation, class, inheritance, polymorphism, persistence, etc.Unit 16“Security” is an all-encompassing term that describes all the concepts, techniques, and technologies to protect information from unauthorized access. There are several requirements for information security.Confidentiality: hiding data, usually with encryption, to prevent unauthorized viewing and access.Authenticity: the ability to know that the person or system you are communicating with is who or what you think it is.Access control: once a person or system has been authenticated, their ability to access data and use systems is determined by access controls.Data integrity: providing assurance that an information system or data is genuine.Availability: making sure that information is available to users in a secure way.To prevent unauthorized access, some type of identification procedure must be used. These vary from passwords to physical access object (access cards, etc.) to biometric devices that verify some type of personal characteristic, such as a fingerprint.Some of the most secure access control systems address both identification and authentication. Identification involves verifying that the person’s name or other identifying feature is listed as an authorized user; authentication refers to determining whether or not the person is actually who he or she claims to be.Unit 17A distributed system is a collection of independent computers which appear to the users of system as a single computer. Nearly all large software systems are distributed. For example, enterprise-wide business systems must support multiple users running common applications across different sites.A distributed system encompasses a variety of applications, their underlying support software, the hardware they run on, and the communication links connecting the distributed hardware. The largest and best-known distributed system is the set of computers, software, and services comprising the World Wide Web, which is so pervasive that it coexists with and connects to most other existing distributed systems. The most common distributed systems are networked client/server systems. Distributed systems share the general properties described below.●Multiple nodes●Message passing or communication●Resource sharing●Decentralized control●Concurrency or parallelism●Fault tolerance●Heterogeneity●OpennessDistributed systems have many inherent advantages, especially over centralized systems. Some applications are inherent distributed as well. In general, distributed systems:●Yield higher performance●Allow incremental growth●Allow one user to run a program on many different machines in parallel ●Provide higher reliability● .●●。
1.(P1) Computer science deals with the theoretical foundations of information and computation, together withpractical techniques for the implementation and application of these foundations, such as programming language theory, computational complexity theory, computer graphics and human-computer interaction.计算机科学涉及信息和计算的理论基础,以及这些基础的实施和应用的实际技术,如编程语言理论,计算复杂性理论,计算机图形学和人机交互。
2.(P17) The most important piece of graphics hardware is the graphics card, which is the piece of equipment thatrenders out all images and sends them to a display. There are two types of graphics cards: integrated and dedicated. An integrated graphics card, usually by Intel for use in their computers, is bound to the motherboard and shares RAM (Random Access Memory) with the CPU, reducing the total amount of RAM available. This is undesirable for running programs and applications that use a large amount of video memory. A dedicated graphics card has its own RAM and Processor for generating its images, and does not slow down the computer.Dedicated graphics cards also have higher performance than integrated graphics cards. It is possible to have both dedicated and integrated graphics card, however once a dedicated graphics card is installed, the integrated card will no longer function until the dedicated card is removed.最重要的一块图形硬件是显卡,是一件呈现出所有的图像,并将它们发送到一个显示器的设备。
有两种类型的显卡:集成和专用。
集成的显卡,通常由英特尔在他们的计算机上使用,被绑定到主板并且与中央处理器共享内存(随机存取存储器),减少了可用的内存总量。
这对于使用大量视频内存的程序和应用来说是不可取的。
专用显卡有它自己的内存和处理器,用于生成它的图像,并且不会减慢计算机的速度。
专用显卡也比集成显卡有更高的性能。
有可能既有专门的也有集成的显卡,但是,一旦安装了专用显卡,集成显卡将不再起作用,直到专用显卡被移除。
3.(P18) Channel I/O requires the use of instructions that are specifically designed to perform(执行)I/Ooperations. The I/O instructions address(处理)the channel or the channel and device; the channel asynchronously(异步的)accesses all other required addressing and control information. This is similar to DMA, but more flexible.I/O通道需要使用专门设计来执行I/O操作的指令。
I/O指令处理通道或通道和设备;通道异步访问所有其他所需的寻址和控制信息。
这是类似于DMA,但更灵活。
4.(P19) 调制解调器是在模拟和数字信号之间进行转换的设备,它经常用于实现计算机之间通过电话线的互相通信。
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。
Modem is a device that converts analog(模拟)signals to digital signals or conversely(相反地). It is often used to communicate between computers via(渠道)telephone lines. If the two modems can send data to each other, they use full-duplex mode; if only one modem can transmit data, they use half-duplex mode.5.(P21) We many have defined our last generation of computer and begun the era of generationless computers.Even though computer manufacturers talk of “fifth” and “sixth” generation computers, this talk is more a marketing play than a reflection of reality.我们已经定义了我们的上一代计算机,并且开始了计算机的无代时代。
即使计算机制造商谈论的“第五”和“第六”代电脑,这个说法比起现实的反映更像是一个营销游戏。
6.(P21) Although microprocessors are still technically considered to be hardware, portions of their function arealso associated with computer software. Since microprocessors have both hardware and software aspects they are therefore often referred to as firmware.虽然微处理器仍然在技术上被认为是硬件,它们的部分功能也与计算机软件有联系。
因为微处理器有硬件和软件两个方面,因此,他们往往被称为固件。
7.(P22) Electronic hardware consists of interconnected(互联的)electronic components(元件/组件)whichperform analog or logic operations on received and locally stored information to produce as output or store resulting new information or to provide control for output actuator mechanisms(机制).Electronic hardware can range from individual chips/circuits to distributed information processing systems.Well-designed electronic hardware is composed of functional modules which inter-communicate via preciselydefined interfaces.电子硬件是由互连的电子元件组成的,这些电子元件对接收到的和本地存储的信息执行模拟或逻辑运算,以产生输出或存储产生的新信息或提供控制输出执行机构的机制。
电子硬件的范围可以从单独的芯片/电路到分布式信息处理系统。
精心设计的电子硬件是由相互通信的功能模块,通过精确定义的接口组成。
8.(P23) Hardware logic is primarily a differentiation of the data processing circuitry from other more generalizedcircuitry. For example, nearly all computers include a power supply which consists of circuitry not involved in data processing but rather powering the data processing circuits. Similarly, a computer may output information to a computer monitor or audio amplifier which is also not involved in the computational process.硬件逻辑主要是从其他更广义电路的数据处理电路的分化。
例如,几乎所有的计算机都包括一个电源,该电源由不涉及数据处理的电路组成,而是提供数据处理电路的电源。
同样地,计算机可以输出信息到计算机监视器或音频放大器,也不涉及计算过程。
9.(P23 3段)10.(P30) The Space Shuttle avionics software represents a successful integration of many of the computer industry'smost advanced software engineering practices and approaches. Beginning in the late 1970's this software development and maintenance project has evolved one of the world's most mature software processes applying the principles of the highest levels of the Carnegie Mellon University Software Engineering, Institute's Capability Maturity Model, Trusted Software methodology, and ISO 9001 Standards. This software process, considered to be a “best practice” by many software industry organizations includes state-of-the-practice software reliability engineering methodologies. Lve-critical Shuttle avionics software produced by this process is recognized to be highest quality and highest reliability software in operation in the world.航天飞机的航空电子设备软件代表了许多计算机行业最先进的软件工程实践和方法的成功整合。
