Zhang Ning: Well, there might many causes for system crash. One of them is software. The simplest operation like installing and uninstalling might cause a crash in system. Problems within the system may also do that, so you have to be very careful when deleting DLL files, modifying Windows registry, or upgrading the operating system. Another cause is the hardware problem. Have you tried backing up the files? It would be a great help in system restoration when the problem doesn’t lie in the hardware. Cheng Hong: The service personnel installed a ghost program for me when I bought the computer. Will I lose the data in my hard disk if it is restored? Qian Liang: Not except the data on C: drive, where files on your desktop or in My Documents are stored. You may move them into other locations with a bootable disk or under DOS if there are any. Cheng Hong: There are a lot of learning materials in My Documents and on the desktop. Would you please help me transfer them? It might save me the trouble of calling for customer services, and what’s more important, I’d learn a lot from you. Qian Liang: No problem.

计算机专业英语影印版(Computing Essentials 2008课后答案大全)第三单元Basic Application Software
Crossword Puzzle Answers:Open Ended Questions:1.Explain the difference between general-purpose and special-purpose applications.General-purpose applications are widely used in nearly every discipline and occupation. They include word processors, spreadsheets, database management systems, and presentation graphics.special-purpose applications are more narrowly focused on specific disciplines and occupations, such as graphics programs, audio and video editors,2.Discuss the common features of most software programs. Describe the new interfaceintroduced with 2007 Microsoft Office.The newest Office version, 2007 Microsoft Office, has a redesigned interface that is intended to make it easier for users to find and use all the features of an application. This new designintroduces ribbons, contextual tabs, galleries, and more.• Ribbons replace menus and toolbars by organizing commonly used commands into a set of tabs.These tabs display command buttons that are the most relevant to the tasks being performed by the user.• Contextual tabs are tabs that appear automatically. These tabs only appear when they are needed and anticipate the next operations to be performed by the user.• Galleries simplify the process of making a selection from a list of alternatives. This isaccomplished by replacing many dialog boxes with visual presentations of potential results.This new interface is the first major change in over a decade.3.What is the difference between a function and a formula? How is a formula related to what-if analysis?A formula is an instruction to calculate or process. Functions are prewritten formulas providedby the spreadsheet program that perform calculations such as adding a series of cells. If a change is made to one or more numbers in a spreadsheet, all related formulas will automaticallyrecalculate and charts will be recreated. Observing these changes is what-if analysis.4.What are presentation graphics programs? How are they used?Presentation graphics are programs that combine a variety of visual objects to create attractive, visually interesting presentations. They are excellent tools to communicate a message and to persuade people.5.What is the difference between an integrated package and a software suite? Whatare the advantages and disadvantages of each?An integrated package is a single program that provides the functionality of a wordprocessor, spreadsheet, database manager, and more. The primary disadvantage of an integrated package is that the capabilities of each function (such as word processing) are not as extensive as in the individual programs (such as Microsoft Word). The primary advantages are cost and simplicity.A software suite is a collection of separate application programs bundled together andsold as a group. While the applications function exactly the same whether purchased in a suite or separately, it is significantly less expensive to buy a suite of applications than to buy each application separately.1. Expanding Your Technology exercise #3 Shareware explores how shareware programswork and what the risks involved in using them are.2.Writing About Technology exercise #1 Acquiring Software asks the student to explorefive ways of acquiring software. And asks if it is wrong to obtain and use unauthorized software.Web Tools1.Applying Technology exercise #3 Corel WordPerfect Office Suite has the studentresearch the suite and compare/contrast it to the Microsoft Office suite.

Unit 3 Computers全单元练习含答案 精校打印版
Unit 3Computers你肯定经常看到WWW这三个字母，它代表什么，是什么意思，你了解吗？下面就让我们一起来看看吧！If you watch TV, visit the mall, or do anything at all, you'll have chances to see the three famous letters, WWW！So what does it stand for? What does it all mean?Well, in general, WWW stand for “World Wide Web”. Most people confuse the Internet with the World Wide Web. However, there is a difference. The Internet is made up of thousands of computers that are connected worldwide. WWW or World Wide Web, is what your computer uses to check out the Internet. For example, your computer uses browsers, such as Internet Explorer or Netscape (网景浏览器) to let you see and hear all the cool pictures, information, music and sounds on the Internet.There are three things you need to surf the World Wide Web.First, you must have a computer that has a modem. A modem is like a telephone, which allows your computer to dial and connect to the Internet.Second, your computer must have a browser! An example of a browser would be Internet Explorer or Netscape. The browser allows you to see the information and graphics on the Internet.Third, you must have an Internet Service Provider. This is known as an ISP (网络服务提供商)．The most commonly used ISPs are companies like AOL, Earthlink (地球连线), Compuserve (计算机服务). In order to connect to the Internet, you have to pay for the service. Just like if you have cable TV, your parents have to pay for it. In order to connect to the Internet you have to pay. Usually, this will cost you $19.95 a month.1．confuse v t.使混乱；使困惑2．connect v t. 连接；联合；关联3．browser n.

II．Translate the following terms or phrases from English into Chinese and vice versa:
Thedifficulty of writing programs in themachinelanguage of 0s and 1s led first to the development of assembly language, which allowsprogrammersto use mnemonics for instructions and symbols for variables. Such programs are thentranslatedby a program known as an assembler into the binary encoding used by thecomputer. Other pieces of system software known as linking loaderscombinepieces of assembled code and load them into the machine’s mainmemoryunit, where they are then ready for execution. The concept of linkingseparatepieces of code was important, since it allowed “libraries” ofprogramsto be built up to carry out common tasks—a firststeptoward the increasingly emphasized notion of softwarereuse. Assembly language was found to be sufficientlyinconvenientthat higher-level languages (closer to natural languages) were invented in the 1950s for easier, fasterprogramming; along with them came the need for compilers, programs that translatehigh-levellanguage programs into machine code. As programming languages became morepowerfuland abstract, building efficient compilers that create high-quality code in terms ofexecutionspeed and storage consumption became an interesting computer science problem in itself.
