计算机专业英语影印版(Computing Essentials 2008)课后答案大全——第六单元Chapter 6 The System Unit
Crossword Puzzle Answers:
Open Ended Questions:
1.Describe the four basic types of system units.
? Desktop system units contain the system’s electronic components and selected secondary
storage devices. Input and output devices are located outside the system unit.
? Notebook system units are portable and much smaller and contain the electronic components, selected secondary storage devices, and input devices
? Tablet PC system units are highly portable devices that support the use of a stylus or pen to
input commands and data.
? Handheld computer system units are the smallest and contain an entire computer system
2.Describe the two basic components of the CPU.
? Control unit: tells the rest of the computer system how to carry out a program’s instructions. It directs the movement of electronic signals between memory, which temporarily holds data,
instructions, and processed information, and the arithmetic-logic unit. It also directs these control signals between the CPU and input and output devices.
? Arithmetic-logic unit: The arithmetic-logic unit performs two types of operations: arithmetic and logical. Arithmetic operations are, as you might expect, the fundamental math operations: addition, subtraction, multiplication, and division. Logical operations consist of comparisons. 3.What are the differences and similarities between the three types of memory?
Random-access memory (RAM) chips hold the program and data that the CPU is presently processing. RAM is called temporary or volatile storage because everything in most types of RAM is lost as soon as the microcomputer is turned off.
Read-only memory (ROM) chips have programs built into them at the factory. Unlike RAM chips, ROM chips are not volatile and cannot be changed by the user.
C omplementary metal-oxide semiconductor (CMOS) chips provide flexibility and
expandability for a computer system. They contain essential information that is required every time the computer system is turned on.
4.Identify five expansion cards and describe the function of each.
? Sound cards: These cards accept audio input from a microphone and convert it into a form that can be processed by the computer. Also, these cards convert internal electronic signals to audio signals so they can be heard from external speakers.
? Modem cards: These cards allow distant computers to communicate with one another by
converting electronic signals from within the system unit into electronic signals that can travel over telephone lines and other types of connections.
? Network interface cards (NIC): These cards are used to connect a computer to one or more other computers. The network adapter card typically connects the system unit to a cable that connects to the network.
? TV tuner cards: TV tuner cards contain a TV tuner and a video converter that changes the TV signal into one that can be displayed on your monitor.
? Video cards: These cards connect the system board to the computer’s monitor, and they convert the internal electronic signals to video signals so they can be displayed on the monitor.
5.Identify and describe four standard ports and three specialized ports.
The four standard ports are:
? Serial ports are used for a wide variety of purposes. They are often used to connect a mouse, keyboard, modem, and many other devices to the system unit. Serial ports send data one bit at a time and are very good for sending information over a long distance.
? Parallel ports are used to connect external devices that need to send or receive a lot of data over a short distance. These ports typically send eight bits of data simultaneously across eight parallel wires. Parallel ports are mostly used to connect printers to the system unit.
? Universal serial bus (USB) ports are gradually replacing serial and parallel ports. They are faster, and one USB port can be used to connect several devices to the system unit.
? FireWire ports are as fast as USB 2.0 ports and provide connections to specialized FireWire devices such as camcorders.
The three specialized ports are:
? Musical instrument digital interface (MIDI) ports are a special type of serial port for connecting musical instruments to a sound card. The sound card converts the music into a series of digital instructions. These instructions can be processed immediately to
reproduce the music or saved to a file for later processing.
? Small computer system interface (SCSI) ports are a special type of highspeed parallel port for connecting a series of input and/or output SCSI devices to a single SCSI controller card. This arrangement allows several devices to communicate with the system unit through a single slot on the system board.
? Infrared Data Association (IrDA) provide a wireless mechanism for transferring data between devices. Instead of cables, the IrDA ports from each device are directly aligned and infrared light waves are used to transmit data. One of the most common applications is to transfer data from either a handheld or notebook computer to a desktop computer.

计算机专业英语影印版(Computing Essentials 2008)课后答案大全——第八单元Chapter 8 Secondary Storage
Crossword Puzzle Answers: Open Ended Questions: 1.Discuss the traditional and high-capacity floppy disks. The traditional floppy disk is the 1.44 MB 31/2-inch disk. The most common type is labeled 2HD, which means “two-sided, high-density” and have a capacity of 1.44 MB.Floppy disks have a thin exterior jacket made of hard plastic to protect the flexible disk inside. High-capacity disks, also known as floppy-disk cartridges, are rapidly replacing the traditional floppy disk. They are 31/2 inches in diameter, and are able to store more information, are thicker, and require special disk drives. 2.What are the three types of hard disks? Describe three ways to improve hard-disk performance. There are three types of hard disks: internal hard disk, hard-disk cartridge, and hard-disk pack.
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
