Ask the students if they have ever used utility software. If they say no, ask about Adobe Reader.Show students widgets like those in Figure 3-5. Ask the students to describe how they are used and how frequently.TEACHER TIPDemonstrate how to use Adobe Reader and discuss the fact that you do not have to have the software that created a document to view the document if saved in Adobe.FIGURESFigure 3-3, Figure 3-4, Figure 3-5CLASSROOM ACTIVITIESAssign a Project: Have students look on classroom or home computers for utility software. Have them make a list of all the utility software they find.Quick Quiz: A(n) _________ is a specialized utility program that appears on a computer’s screen-based desktop, looks like a control, and might display a snippet of information. (Answer: desktop widget)_________ is designed to help you monitor and configure settings for your computer system equipment, the operating system, or application software. (Answer: Utility software)Device Drivers (124)LECTURE NOTESLead a brief discussion of device drivers to reinforce the concept presented in Chapter 2 that when you install a peripheral device you must often also install software to make it work. If you want to give your students a concrete example, use the following: Suppose your computer uses an ink jet printer, but you decide to purchase a new laser printer and use it instead. After you connect the printer, you need to make sure the computer sends the appropriate electronic signals, so you must install software to do this. This software—called a printer driver—is usually supplied with the printer. Some operating systems, such as Windows, contain pre-installed drivers for many popular printers. If the operating system contains the driver for your printer, you just need to select the appropriate printer. If you cannot find the driver, it is often available on the Internet. Go to the Internet and find a printer device driver.TEACHER TIPIf you are teaching in a lab situation or have the students in lab class, you might discuss that it is not sufficient to have the correct driver. If the printer is networked, you will also need the address of the printer.FIGURESFigure 3-6CLASSROOM ACTIVITIESAssign a Project: Have students browse and search the Internet for device drivers. If they have a printer at home, have them find the appropriate driver. If not, have them find the lab printer driver.Quick Quiz: A(n) _________ is software that helps a peripheral device establish communication with a computer.

(Answer: True)SECTION B: POPULAR APPLICATIONSSECTION B OPENER QUESTION:032200 Just about everyone has used iTunes software to download music. iTunes software also allows you to list the songs you’ve downloaded, delete songs, find songs, and organize your music into play lists. These features of iTunes are similar to what type of software?Word processing softwareSpreadsheet softwareDatabase softwareGroupware(Answer: c)Document Production Software (125)LECTURE NOTESExplain that document production software includes a wide variety of packages, from simple word-processing software to more complicated packages that enable creation of desktop published newsletters as well as home pages for Web sites. Ask students to identify the kind of software they’ve used, if any and discuss for what they used it. Show a document that has been created in word processing software and enhanced in desktop publishing software. You might also show the same information as a Web page after using Web authoring software.Demonstrate how the same data can be transferred from one package to another.Have students try different fonts and formatting options. Have each student format the same sentence and have the class determine which is the most readable.Point out that while the grammar check feature included in many word processing software packages is helpful, it is not always correct. Show an example of this.Type a line with a misspelling which the spell checker will catch. Type another line with a misspelling the spell checker will not catch, such as tow and two. You may want to suggest to your students that they walk away from their work before a final proofreading, or ask someone else to proofread their documents. FIGURESFigure 3-7, Figure 3-8, Figure 3-9, Figure 3-10, Figure 3-11TEACHER TIPHave students use two different word processing software. Ask students to compare their experiences in using the two programs. CLASSROOM ACTIVITIESAssign a Project: Have students create a simple document using word processing software and explore the spelling checker, grammar checker, and thesaurus. Quick Quiz: _________ software has replaced typewriters for producing many types of documents. (Answer: Word processing)True/False: Desktop publishing software helps you design Web pages. (Answer: False)The _________ for a document refers to the way that all the elements of the document are arranged on the page. (Answer: format)Spreadsheet Software (130)LECTURE NOTESThe best way for students to understand the purpose and features of spreadsheet software is to let them work directly with popular spreadsheet applications such as Microsoft Excel. If it is not possible for students to work with spreadsheet software in class, use the figures in this section to explain how spreadsheet software works. Emphasize to your students that a well-organized worksheet should be easily understood by anyone using it. Have your students use discrete categories that are clearly labeled when creating a worksheet. Make sure your students enter a simple formula.One of the most confusing aspects of spreadsheet operations is the use of relative and absolute cell references. Be sure to cover relative and absolute cell references thoroughly, until students understand the differences between them. TEACHER TIPTo clarify the idea of absolute and relative cell references, create a field such as interest rate and have the student apply it to a list of balances. If you put the interest rate in one column with nothing following and have them copy the formula, they will quickly see why absolute cell references are neededFIGURESFigure 3-12, Figure 3-13, Figure 3-14, Figure 3-15CLASSROOM ACTIVITIESQuick Quiz:The intersection of a row and column on a spreadsheet is a(n) _________. (Answer: cell)True/False: Microsoft Word is an example of spreadsheet software. (Answer: False)A(n) _________ reference never changes when you insert rows or copy or move formulas. (Answer: absolute)“Number Crunching” Software (133)LECTURE NOTESContrast spreadsheet software with number crunching software. While spreadsheets allow you to create your own formulas and scenarios, number crunching software can provide the formulas and opportunities for you. Give examples of tasks that you can perform with number crunching software, such as statistical analysis and mathematical modeling.Accounting and finance software, personal finance software, online banking, and small business accounting software all help users manage their money, from tracking expenses and income, to making investments, to paying bills. Discuss the difference between this type of numeric software and spreadsheets. On the demonstration computer, show sample files in a personal finance package and in a spreadsheet package.FIGURESFigure 3-16CLASSROOM ACTIVITIESClass Discussion: Ask students if they’ve used any “number crunching” software, such as tax preparation software or personal finance software. What programs and for what uses? Quick Quiz:_________ software helps you analyze large sets of data to discover relationships and patterns. (Answer: Statistical)True/False: Taxes are best done on a spreadsheet. (Answer: False)Database Software (134)LECTURE NOTESA good way of describing a database is in terms of a filing cabinet. The cabinet is a database, with each drawer being a table, and each piece of paper being a record.Refer to Figure 3-17 and discuss a database record.Students should think of databases as electronic filing systems that provide efficient storage, management, and retrieval of information. Information in a database is organized much like files in a file cabinet; information is grouped with other, similar information, everything is labeled, and there is a sorting order (alphabetic, numeric, etc).Review the parts of a database. Databases are comprised of records, which are compilations of information used to describe each object in a database. Records are comprised of fields, which are groups of cells that contain the same type of information, referenced by the same name. Discuss the reasons for using a database program instead of a spreadsheet program. (Easy retrieval of like data)How do you find information in a database? Queries allow users to ask questions about the information in the database. TEACHER TIPIf your school uses on-line registration, relate it to databases. You could also include a listing of classes.FIGURESFigure 3-17, Figure 3-18, Figure 3-19, Figure 3-20CLASSROOM ACTIVITIESClass Discussion: Have each student bring an index card with their favorite song, performer and other predefined information. Use the data from these cards to form a database. If you have access to Microsoft Access, you could use it. Quick Quiz:A(n) _________ is a collection of data that is stored on one or more computers. (Answer: database)True/False: A record holds data for a single entity—a person, place, thing, or event. (Answer: True)True/False: A database can contain any type of data. (Answer: True)Graphics Software (137)LECTURE NOTESDistinguish among the different types of graphics software, such as paint software, photo-editing software, drawing software, 3-D graphics software, and presentation software. Show examples of each, if possible. Discuss that graphics can have different formats and each has its own extension such as BMP, GIF, JPEG, or WMF.Have the student create a drawing of some type using paint.Have the student open a JPEG document in paint and save it as a bmp. Examine the size of each.TEACHER TIPIf your students are interested in pursuing computer-related careers, discuss the kinds of jobs that involve computer graphics.

(software suite)Software Copyrights and Licenses (146)LECTURE NOTESIf your school has a software use policy, you might want to provide your students with a copy in conjunction with this section.Make sure your students understand what it means for software to be copyrighted. Under U.S. copyright law, rights granted to the copyright holder include the right to copy, distribute, or sell the software, and to modify the software. Rights granted to the user of copyrighted materials include use of the software on the user’s computer (including installing the software on the hard drive and making a back-up copy), to copy entered data without restriction, and to copy or modify the software under certain circumstances.Make sure students understand that just because they purchase software they do not necessarily own the rights to the software, just the right to use it. This is often a difficult concept to understand. Explain that they are purchasing a right to use (similar to a never ending lease) as opposed to outright ownership. Students have difficulty distinguishing among software copyright, copy protection, and write protection. To check your students' understanding, you might hold up a disc and ask, "Is this disc copyrighted, copy protected, or write protected?" The software on the disc is probably copyrighted, but the disc itself is not. It is unlikely that the disc is copy protected—this form of protection has fallen out of favor with software publishers. Discuss different licensing agreements. Use software licensed by the school as an example. For example, you might have a Microsoft site license. What can and can’t you do with that. You might belong to the Microsoft academic alliance. How does that work? Other examples would help.Emphasize the concept of shrink-wrap licenses and installation agreements. What are buyers agreeing to? Review the license in Figure 3.32 to see if students understand the legalese.Explain freeware and discuss the inherent security issues. By giving software away, the publisher may be giving viruses away, as well.FIGURESFigure 3-30, Figure 3-31, Figure 3-32, Figure 3-33CLASSROOM ACTIVITIESAssign a Project: Have a license agreement from different types of software such as freeware, demoware, commercial and open source and have the student identify the difference in the agreements. Ask the students if they have ever used or purchased pirated software and if they realized it was illegal. This could provide an opportunity for an ethics discussion.Quick Quiz:A(n) _________ is a form of legal protection that grants the author of an original work an exclusive right to copy, distribute (sell), and modify that work, except under special circumstances described by the law. (Answer: copyright)True/False: A software license is a legal contract. (Answer: True)Copyrighted software which is marketed under a “try before you buy” policy is known as: FreewareSharewareOpen source Public domain (Answer: b)LAB ACTIVITYHave students browse and search the Internet for public domain software. Have them view the system requirements and then check their own computer systems. Will the software run on their systems?SECTION D: INSTALLING SOFTWARE AND UPGRADESSECTION D OPENER QUESTION:032400 Suppose that you’re looking for software to convert a YouTube video into a format you can use with Windows Media Player or iMovie.

Perform an installation similar to the one illustrated in Figure 3-37. Consider demonstrating a standard and a customized installation. Be sure to explain to students how to change customized options, and how to add or remove program features at a later date.The Registry plays an important role in the boot process, providing technical information about the configuration of your computer. It contains a myriad of information about your computer and your software. Explain to students that when they change configuration information using the Control Panel or various settings dialog boxes in applications programs, that they are making changes to the Windows Registry.Demonstrate an installation from the Web. Caution students that viruses are often disguised as self-installing files, so they should download and install software only from reliable sources. Demonstrate how to work with zip files and to run a setup program to complete the installation. A perfect demonstration would be the installation of an update to virus software. Have students go to the Web site and walk them through the file selection to download.Show how to uninstall an application. Explain it is not just a matter of deleting files and the desktop icon.Demonstrate unzipping a file and where the results are placed.If you use SAM, you could use the entering the product key as an example of product activation.FIGURESFigure 3-36, Figure 3-37, Figure 3-38, Figure 3-39CLASSROOM ACTIVITIESClass Activity: Have students install a piece of software and then uninstall it.Installing Portable Software and Web Apps (158)LECTURE NOTESPortable software is designed to run on and from removable storage.

FIGURESFigure 3-40, Figure 3-41CLASSROOM ACTIVITIESAssign a Project: Have students visit and view the available portable software.Quick Quiz:_____________ is designed to run from removable storage, such as a CD or USB flash drive. (Answer: Portable software)True/False: A Web application is software that is accessed with a Web browser. (Answer: True)True/False: All Web applications require installation. (Answer: False)Software Updates (159)LECTURE NOTESExplain why students should update software. Discuss the difference between a software patch and a service pack.Discuss what happens to the old version when an update is installed.TEACHER TIPAs a demonstration of updating software, consider upgrading the Windows operating system by downloading a service pack from Microsoft’s Web site. CLASSROOM ACTIVITIESClass Discussion: Ask students to differentiate between updates, patches, and service packs.Quick Quiz:A(n) _________ is a small section of program code that replaces part of the software you currently have installed. (Answer: software patch)True/False: Software publishers regularly update their software to add new features. (Answer: True)True/False: It is rarely a good idea to install patches and service packs when they become available. (Answer: False)Uninstalling Software (160)LECTURE NOTESExplain that in Windows and Mac OS, you generally cannot remove a software application by simply deleting its files. Instead, you must run an uninstall routine to remove the software. The uninstall routine finds and removes the files the setup program copied to various folders and then restores any settings the setup program changed in the Windows Registry.Demonstrate how to uninstall software. Uninstall one of the applications you installed earlier using an uninstall tool provided by the application. FIGURESFigure 3-42, Figure 3-43LAB ACTIVITYThe New Perspectives Lab “Installing and Uninstalling Software” deals with issues that relate to this section of the textbook. You might want to go through the lab during class time if you have a computer with a projection device. Alternatively, assign this lab for students to do on their own.SECTION E: SECURITY SOFTWARESECTION E OPENER QUESTION:032500 Let’s assume that you have antivirus software installed on your computer and it is up to date.
