Codinggenerally referstothe writing of programs for given program specification，while programming includes the task of preparing the program specification as well as that of writing the programThe text of aprogram is sometimes referred to as code，and lines of program text are referred to as lines of code，especiallyinthe caseofmachine languageprogramsThetermcoderis used to describe a person engagedexclusively inimplementing programspecifications prepared byothers.译：编程有时是相反的编码。编码一般是指写作程序给定程序规范，而编程包括任务的准备程序的规范以及编写程序。该程序文本有时称为代码，和行程序文本称为行代码，特别是在案件的机器语言程序。这个词编码是用来形容一个人专门从事项目规格由他人准备。3、Whats, actually involved in programmingthe actual process of writing programs?Heres a quick overview of the process：1. Write a program2. Compile the program3. Run the program4. Debug(调试) the program5. Repeat the whole process until the program is finished译：什么是实际参编写程序的过程？这里有一个快速的过程概述：1。写一个程序。2。编译程序。3。运行程序。4。调试程序。5。重复整个过程，直到程序结束。4、A computer system includes a computer, peripheral（外围的）devices, and software. The electric, electronic, and mechanical devices used for processing data are referred to as hardware. In addition to the computer itself, the term “hardware” refers to components called peripheral devices that expand the computers input, output, and storage capabilities. Computer hardware in and of itself does not provide a particularly useful mind tool. To be useful, a computer requires a set of instructions, called software or a computer program, which tells the computer how to perform a particular task. Computers become even more effective when connected to other computers in a network so users can share information.译：一个计算机系统包括一台计算机，外围设备和软件。电气，电子，机械设备用于处理数据称为硬件。除了电脑本身而言，“硬件”是指被称为外围设备的组件设备，扩大计算机的输入，输出，存储能力。硬件本身并没有提供一个特别有用的思维工具。计算机需要一套有益的指令，称为软件或计算机程序，告诉计算机如何执行特定任务。让电脑变得更加有效，当连接到其他计算机网络，使用户可以共享信息。5、In software, a bug is an error in coding or logic that causes a program to malfunction or to produce incorrect results. Minor bugsfor example, a cursor that does not behave as expectedcan be inconvenient or frustrating, but not damaging to information. More severe bugs can cause a program to “hang” (stop responding to commands) and might leave the user with no alternative but to restart the program, losing any previous work that has not been saved. In either case, the programmer must find and correct the error by the process known as debugging. Because of the potential risk to important data, commercial application programs are tested and debugged as completely as possible before release. Minor bugs found after the program becomes available are corrected in the next update; more severe bugs can sometimes be fixed with special software, called patches, that circumvents (规避) the problem or otherwise alleviates (减轻) its effects.译：在软件中，错误是编码或逻辑错误导致程序发生故障或产生不正确的结果。较轻微的错误，一个游标，并不会表现为预想的不便或令人沮丧，但不损害信息。较严重的错误会导致程序“挂”（停止响应命令），可能会让用户惟有重启程序，失去以往任何未保存的工作。在任何情况下，程序员必须发现和纠正错误的过程称为调试。由于潜在的风险的重要数据，商业应用程序的测试和调试尽可能在这之前完全释放。小错误发现后，程序可纠正在下次更新；更严重的错误，有时可固定有特殊的软件，称为斑块，规避问题或者减轻其影响。6、Software engineering is an area of software development in which computer scientists and engineers study methods and tools that facilitate（使变得容易）the efficient development of correct, reliable, and robust computer programs. Research in this branch of computer science considers all the phases of the software life cycle, which begins with a formal problem specification, and progresses to the design of a solution, its implementation as a program, testing of the program, and program maintenance. Software engineers develop software tools and collections of tools called programming environments to improve the development process. For example, tools can help to manage the many components of a large program that is being written by a team of programmers.译：在软件工程领域的软件开发中，计算机科学家和工程师的研究方法和手段，使高效发展的正确，可靠，和强大的计算机程序变得容易。这一分支的研究，考虑到各阶段的计算机科学软件生命周期，从正式的问题说明，并发展到解决方案的设计，它的实施作为一个程序，测试程序，和程序维护。软件工程师开发软件工具以及被称为编程环境的工具集，改进开发过程。例如，软件工具可以帮助管理的许多组成部分的正在编写的大型程序程序员小组。四， 句子翻译2题（20%）1、The fact that IBM, a company of such corporate prestige, would enter this market convinced businesses that the microcomputer was more than a passing fad.译：像IBM这种信誉的公司即将进入微机市场，这一事实使人们坚信微机商业不是昙花一现。2、The purpose of storage hardware is to provide a means of storing computer instructions and data in a form that is relatively perma
