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。

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4章操作系统第一部分阅读和翻译A部分 Windows 71. 简介Windows 7是微软最新发布的windows版本,这一系列微软制造的操作系统主要用于个人电脑,其中包括家庭和商业台式电脑、笔记本电脑、上网本、平板电脑、和媒体中心电脑。

(见图4.1)Windows 7于2009年7月22日开始生产,并在2009年10月22日零售,这个时间距其推出其前任Windows Vista不到三年时间。

与Windows 7相对应的Windows server 2008 R2,也是同年发布。

不像其前一操作系统vista，windows7 引入了大量的新特性，更集中于增量升级的windows线，目标是兼容已经在vista中兼容的应用程序和硬件。

微软在2008年的报告中关注于对于多点触控的支持，以及一个重新设计的windows shell和一个新的任务栏，并将其称之为Superbar，还有一个称之为家庭组的网络系统，注重性能改进。

之前版本的windows 系统中的一些标准的应用程序，包括windows日历，windows邮件，windows movie maker，和windows相片画廊在windows 7中并没有包含进来，而大多数是作为Windows Live Essentials套件单独免费进行提供的。

2. 发展最初，微软计划用一个代号为Blackcomb的windows版本来继承Windows XP(代号惠斯勒)和Windows Server 2003。

微软计划在Blackcomb中设计的主要功能包括在搜索中的加强，查询数据以及一个先进的存储命名系统。

然而，一个临时的，更小的，代号为Longhorn 的版本在2003年发布了。

微软在2003年中旬推迟发布了Blackcomb，但是Longhorn获得了大部分当初试图在Blackcomb中实现的特性。

在2003年，相继有三个主要病毒暴露了windows操作系统的一些漏洞，微软改变了其的发展重点，搁置了Longhorn的主要开发工作，主要开发windows xp和windows server 2003的服务包。
