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 compu ter’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.

第7单元计算机网络和因特网第一部分听力和对话对话：搭建无线网络（目前，在Sophie的家里，她已将计算机直接连接到7调制解调器。

现在她想要用无线网络替换现有的有线网络，并且请求Henry和Mark帮忙。

）Henry：放松点，Sophie。

我保证安装比你想象的要容易得多。

简而言之只有4步。

Sophie: 真的吗？那该怎么做呢？Mark: 第一步是确保你拥有所需要的设备。

它们通常包括宽带互联网连接、一个无线路由器和一台带有内置的无线网络支持或一个无线网络适配器的计算机。

Sophie: 让我想想。

嗯，我认为它们现在齐全了。

那接下来怎么办？Mark: 下一个步是连接无线路由器。

关闭调制解调器之后，从计算机的背面拔掉网线，并且将它连入路由器背面的标有互联网、广域网或无线局域网的端口。

同时，网线的另一端应该连接到调制解调器。

Sophie: 那么，我怎么可以知道它们已经正确连上了？Henry: 那很容易。

要检查的话，接通并且启动调制解调器。

等待几分钟让它连接到互联网，然后接通并且启动无线路由器。

在一分钟之后，无线路由器中的互联网、广域网或无线局域网的灯是亮的，表明它已顺利地连接到了调制解调器。

Sophie: 嗯，还有其他的吗？Henry：接着，配置无线路由器。

你应该临时将计算机连接到无线路由器上没有被标为互联网、广域网或无线局域网的其中的一个开放网络端口。

然后，打开IE并输入地址和密码来配置路由器。

Sophie: 我怎样获得地址和密码？Henry: 可以在路由器附带的说明书上找到。

Mark: Sophie，在配置过程中你要特别注意三件事：无线网络的名称也就是服务区标识符、无线加密或者Wi-Fi保护访问，以及能够控制无线网络的管理密码。

顺便说一句，在配置完成之后，从计算机上拔掉网线。

[3]Sophie: 好的，我了解了。

Henry: 现在，我们进入最后一步，连接计算机。

Windows 7应该显示一个包含有可用的无线网络列表的无线网络图标。

《计算机导论》(第2版)习题答案参考计算机导论(第2版)习题答案参考Chapter 1: Introduction to Computers1. Define a computer and discuss its attributes.A computer is an electronic device capable of performing various operations and processes based on a set of instructions. Its attributes include the ability to input, process, store, and output information, as well as the capability to execute complex calculations and perform tasks.2. Differentiate between hardware and software.Hardware refers to the physical components of a computer system, including the central processing unit (CPU), memory, storage devices, input/output devices, and peripherals. Software, on the other hand, represents the non-tangible parts of a computer system, such as programs and data that can be stored and executed by the hardware.3. Explain the concept of data representation and discuss different numbering systems used in computer systems.Data representation refers to the way data is stored and processed by a computer. Different numbering systems include the binary system (base-2), decimal system (base-10), octal system (base-8), and hexadecimal system (base-16). Each system has its own set of symbols and rules for representing numbers and characters.Chapter 2: Computer Hardware1. Discuss the major components of a computer system.A computer system consists of several major components, including the central processing unit (CPU), memory, storage devices, input/output devices, and peripherals. The CPU is responsible for executing instructions and performing calculations, while memory stores data and instructions temporarily. Storage devices are used for long-term data storage, andinput/output devices allow users to interact with the computer system.2. Describe the functions and characteristics of the CPU.The CPU is the central processing unit of a computer system and is responsible for executing instructions and performing calculations. It consists of two main components: the control unit, which manages the execution of instructions, and the arithmetic logic unit (ALU), which performs calculations and logical operations. The CPU's performance is determined by factors such as clock speed, cache size, and number of cores.3. Explain the different types of memory in a computer system.A computer system typically has two main types of memory: primary memory (RAM) and secondary memory (storage devices). RAM, or random access memory, is used for temporary data storage and is volatile, meaning its contents are lost when the power is turned off. Secondary memory, such as hard disk drives and solid-state drives, provides long-term storage for data even when the power is off.Chapter 3: Operating Systems1. Define an operating system and discuss its functions.An operating system is a software that manages computer hardware and software resources. Its functions include providing a user interface, managing memory and storage, coordinating the execution of applications, handling input/output operations, and ensuring system security and stability.2. Explain the difference between a single-user and multi-user operating system.A single-user operating system is designed to be used by one user at a time. It provides a user interface and manages the resources on the computer for the sole user. A multi-user operating system, on the other hand, allows multiple users to access the system simultaneously, sharing resources and executing their own programs concurrently.3. Discuss the concept of virtualization and its advantages.Virtualization is the process of creating a virtual version of a computer system or resources. It allows multiple operating systems to run on a single physical machine, enabling better resource utilization, cost savings, and improved flexibility. Virtualization also provides isolation between different virtual machines, enhancing security and system stability.In conclusion, this article provides a brief overview of the topics covered in the second edition of "Introduction to Computers." It includes explanations and answers to selected exercises, helping readers understand the fundamental concepts of computer science and technology. By studying these topics, readers can gain a strong foundation in computer knowledge and skills.。

附录参考答案Unit 1〖Ex. 1〗根据课文内容回答问题(1) A general-purpose computer has four main sections. They are the arithmetic and logic unit (ALU),the control unit, the memory, and the input and output devices, collectively termed I/O. They are interconnected by busses, often made of groups of wires.(2) The control unit is often called a control system or central controller.(3) ●Read the code for the next instruction from the cell indicated by the program counter.●Decode the numerical code for the instruction into a set of commands or signals for each of the other systems.●Increment the program counter so it points to the next instruction.●Read whatever data the instruction requires from cells in memory, or perhaps from an input device. The location of this required data is typically stored within the instruction code.●Provide the necessary data to an ALU or register.●If the instruction requires an ALU or specialized hardware to complete, instruct the hardware to perform the requested operation.●Write the result from the ALU back to a memory location or to a register or perhaps an output device.●Jump back to the first step.(4) The two classes of operations ALU is capable of performing are arithmetic and logic.(5) Logic operations involve Boolean logic: AND, OR, XOR and NOT.(6) A computer's memory can be viewed as a list of cells into which numbers can be placed or read. Each cell has a numbered "address" and can store a single number.(7) The two principal varieties of computer main memory are random access memory or RAM andread-only memory or ROM.(8) In a PC, the specialized program called the BIOS orchestrates loading the computer's operating system from the hard disk drive into RAM whenever the computer is turned on or reset.(9) Software that is stored in ROM is often called firmware because it is notionally more like hardwarethan software.185(10) I/O is the means by which a computer receives information from the outside world and sendsresults back.〖Ex. 2〗根据下面的英文解释，写出相应的英文词汇(1) input (2) microprocessor (3) program (4) bus (5) hardware (6) memory (7) output (8) cell(9) register (10) address〖Ex. 3〗把下列句子翻译为中文(1) 他进城的目的是买一台新计算机。

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.

As long as we keep working hard on it, we will in due course accomplish the task of mastering English.★Text BComprehension check: c c d a c bLanguage Practice1.g h e c f a b d2.1) adopt 2) account 3) from your point of view 4) ended up 5) furthermore 6) fund7) annual 8) keeping track of 9) pace 10) intends11) perspective 12) deviseUnit 2★Text AVocabularyI. 1. 1) abrupt 2) emotional 3) bless 4) wear and tear 5) dated 6）consequences 7）seemingly 8) in contrast to 9) Curiosity 10) genuine11) primarily 12) sentiments2. 1) W hen you a re c onfronted with m ore t han o ne p roblem, t ry t o s olve t he e asiestone first.2) Water is vital to the existence of all forms of life.3) There is still some confusion among the students about what to do after classto follow up on the subject.4) As a person of s imple living habits, h e needs nothing more than a job and anapartment to be happy.5) It tickled him to think that she’d come to as his advice.3. 1) a lingering, fabricating, s entiments2) fill out, every item, vital, consequences3) be denied, tangible, cherish, attainII.1.It’s a long trip and will take us five hours by bus.2.She arrived early and took a front row seat.3.

Though how the English language came into existence remains a mystery to manypeople，linguists believe that English and most other European languages have descended from a common source: the Indo-European parent language. English was first spoken by the Anglo-Saxons who invaded England in the fifth century. They passed onto us the basic vocabulary of English. In over fifteen centuries of its development, English has enriched itself by massive borrowing. As British immigrants landed in America and established the United States as an independent nation, a new variety was added to the English language : American English. Though some people worry that the language is running out of control, many native speakers of English take pride in the tolerance of their language.★Text BComprehension Check: c c c d b dLanguage Practice1. g e d c b h f a2. 1) give way to 2) predict 3) substantial 4) integrate 5) in transition 6) aspect7) to name a few 8) authority 9) dominate 10) had contributed to 11) unique12) rid yourself ofUnit 8VocabularyI. 1) barking 2) evil 3) brooding, hatched 4) migrant 5) tragedies 6) counterpart7) are complaining/complain 8) grim 9) flocks, fed on 10) vegetation11) patches 12) Scores of2. 1) was lined with people who came to welcome the distinguished foreign guests2) the boss silenced all lively conversation in the office3) wearing a pair of sun glasses, the famous movie star passed the crowded unnoticed.4) looked deserted 5) were stricken by i t3. 1) patches, came into full bloom, were puzzled, mysterious2) throbbed with, sickened, migrant, a chorus 3) had crept into.
