According to the mode of processing, computers are either analog or digital. They can 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, 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.Unit 2 Section A（P34）I．Fill in the blanks with the information given in the text:1．input; output; storage2．Basic Input Output System3．flatbed scanners; hand-held scanners4．LCD-based5．dot-matrix printers; inkjet printers6．disk drives; memory7．Volatile8．serial; parallelII．Translate the following terms or phrases from English into Chinese and vice versa:1．Function key 功能键2．voice recognition module 语音识别模块3．touch-sensitive region 触感区，触摸区4．address bus 地址总线5．flatbed scanner 平板扫描仪6．dot-matrix printer 点阵打印机（针式打印机）7．parallel connection 并行连接8．cathode ray tube 阴极射线管9．video game 电子游戏（港台亦称电玩）10．audio signal 音频信号11．operating system 操作系统12．LCD (liquid crystal display) 液晶显示（器）13．inkjet printer 喷墨打印机14．data bus 数据总线15．serial connection 串行连接16．volatile memory 易失性存储器17．laser printer 激光打印机18．disk drive 磁盘驱动器19．BIOS (Basic Input Output System) 基本输入输出系统20．video display 视频显示器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 disk read-only memory. Unlike floppy and hard disks, which use magnetic charges to represent 1s and 0s, optical disks use reflected light. On a CD-ROM disk, 1s and 0s are represented by flat areas and bumpy areas (called “pits”) on its bottom surface. The CD-ROM disk is read by a laser that projects a tiny beam of light on these areas. The amount of reflected light determines whetherthe area represents a 1 or a 0.Like a commercial CD found in music stores, a CD-ROM is a “read-only” disk. 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 by the publisher.A single CD-ROM disk can store650 megabytes of data. That is equivalent to 451 floppy disks. With that much information on a single disk, the time to retrieve or access the information is very important. An important characteristic of CD-ROM drives is their access rate.Unit 3 Section A（P57）I．Fill in the blanks with the information given in the text:1．artificial; instructions2．low-level; high-level3．low-level4．Machine5．functional; logic6．Statement7．Module8．digitalII．Translate the following terms or phrases from English into Chinese and vice versa:1．storage register 存储寄存器2．function statement 函数语句3．program statement 程序语句4．object-oriented language 面向对象语言5．assembly language 汇编语言6．intermediate language 中间语言，中级语言7．relational language 关系（型）语言8．artificial language 人造语言9．data declaration 数据声明10．SQL 结构化查询语言11．executable program 可执行程序12．program module 程序模块13．conditional statement 条件语句14．assignment statemen t赋值语句15．logic language 逻辑语言16．machine language 机器语言17．procedural language 过程语言18．programming language 程序设计语言19．run a computer program 运行计算机程序20．computer programmer 计算机程序设计员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 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 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; alongwith 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.Unit 4 Section A（P81）I．Fill in the blanks with the information given in the text:1．application; operating2．assemblers3．compiler4．interpreter5．Debugger6．Loop7．device driver8．John von NeumannII．Translate the following terms or phrases from English into Chinese and vice versa:1．inference engine 推理机2．system call 系统调用3．compiled language 编译语言4．parallel computing 平行计算5．pattern matching 模式匹配6．free memory 空闲内存7．interpreter program 解释程序8．library routine 库程序9．intermediate program 中间程序，过渡程序10．source file 源文件11．interpreted language 解释（性）语言12．device driver 设备驱动程序13．source program 源程序14．debugging program 调试程序15．object code 目标代码16．application program 应用程序17．utility program 实用程序18．logic program 逻辑程序19．ink cartridge 墨盒20．program storage and execution 程序的存储与执行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 (连接程序), and loaders (装入程序)—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.Unit 7 Section A（P153）I．Fill in the blanks with the information given in the text:1．Telegraph2．dots; dashes3．Media4．point-to-point5．Analog6．Digital7．text-based8．modemII．Translate the following terms or phrases from English into Chinese and vice versa:1．microwave radio 微波无线电2．digital television 数字电视3．DSL 数字用户线路4．analog transmission 模拟传输5．on-screen pointer 屏幕（触摸屏）上的指示（器）6．computer terminal 计算机终端7．radio telephone 无线电话8．cellular telephone 蜂窝电话（移动电话）9．decentralized network 分散的网络10．wire-based internal network 基于普通网线的内部网络11．fiber-optic cable 光缆12．fax machine 传真机13．wireless communications 无线通信14．point-to-point communications 点对点通信15．modulated electrical impulse 调制电脉冲16．communication(s) satellite 通信卫星17．telegraph key 电报电键18．transmission medium 传输媒体19．cordless telephone 无绳电话20．metal conductor 金属导体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 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 “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.Unit 12 Section A（P272）I．Fill in the blanks with the information given in the text:1．employees2．Hackers3．Crackers4．damage; manipulation5．Worm6．software piracy7．access; backup8．PasswordsII．Translate the following terms or phrases from English into Chinese and vice versa:1．encryption program 加密程序2．deletion command 删除命令3．authorized user 授权的用户4．backup copy 备份的副本5．voltage surge 电涌，浪涌电压6．circuit breaker 断路器7．electronic component 电子器件8．data-entry error 数据输入错误9．electronic break-in 电路中断10．power line 电力线，输电线11．detection program 检测程序12．power source 电源13．destructive computer program 破坏性计算机程序14．computer virus 计算机病毒15．software piracy 软件侵权16．hard-disk drive 硬盘驱动器17．virus checker 病毒检查程序18．primary storage 主存储器19．electronic bulletin board 电子公告板20．surge protector 浪涌电压保护器III．Fill in each of the blanks with one of the words given in the following list, making changes if necessary:A virus or other unwelcome surprise can lurk in your computer system for days or months without discovery. A time bomb is a computer program that stays in your system undetected until it is triggered by a certain event in time, such as when the computer system clock reaches a certain date. A time bomb is usually carried by a virus or Trojan horse. For example, the Michelangelo virus contains a time bomb designed to damage files on your hard disk on March 6, the birthday of artist Michelangelo.A logic bomb is a computer program that is triggered by the appearance or disappearance of specific data. For example, suppose a programmer in a large corporation believes that she is on the list of employees to be terminated during the next cost-cutting campaign. Her hostility (敌意) overcomes her ethical (道德的) judgment, and she creates a logic bomb program that checks the payroll (在职人员名单) file every day to make sure her employment status is still active. If the programmer’s status changes to “terminated,” her logic bomb activates a program that destroys data on the computer.A time bomb or logic bomb might do mischief(祸害) in your computer long before the timer goes off. If the bomb contains a virus, it could replicate and spread to other files. Meanwhile, you might send files from your computer to other computers, not knowing that they are infected.。

Inheritance allows an object to take on the characteristics and functions of other objects to which it is functionally connected. Programmers connect objects by grouping them together in different classes and by grouping the classes into hierarchies. These classes and hierarchies allow programmers to define the characteristics and functions of objects without needing to repeat source code, the coded instructions in a program. Thus, using OOP languages can greatly reduce the time it takes for a programmer to write an application, and also reduce the size of the program. OOP languages are flexible and adaptable, so programs or parts of programs can be used for more than one task. Programs written with OOP languages are generally shorter in length and contain fewer bugs (缺陷), ormistakes, than those written with non-OOP languages.面向对象程序设计语言的一个特别强大的功能，是称为继承的特性。
