No notes for slide
  • To the instructor: This presentation attempts to cover every term in the text, sometimes via a slide, sometimes via the Notes page. Additional material beyond what is in the text is presented via: Occasional “FACTOID” notations on the Notes page, and; Occasional hyperlinks in the slides themselves. ScreenTip text has been added to each hyperlink allowing you to see in advance of selecting the hyperlink where that link will take you. In addition, the last ~20 slides are questions covering the material just presented. They can be used to increase interaction between the instructor and students at the end of each lecture, to ensure students understand the material just presented, etc. Finally, some of the Notes pages include “Discussion questions” for use in encouraging student interaction during the lecture.
  • Key Questions (from the text): 3.1 What are five ways of obtaining application software, tools available to help you learn to use software, three common types of files, and the types of software? 3.2 What are some common features of the graphical software environment? 3.3 What can you do with word processing software that you can’t do with pencil and paper? 3.4 What can you do with an electronic spreadsheet that you can’t do with pencil and paper and a standard calculator? 3.5 What is database software, and what is personal information management software? 3.6 What are the principal uses of specialty software such as presentation graphics, financial, desktop publishing, drawing and painting, project management, computer-aided design, and video/audio editing software?
  • Copyright - the exclusive legal right that prohibits copying of intellectual property without the permission of the copyright holder. Example of freeware: Netscape Navigator & Microsoft Internet Explorer Software license - a contract you sign in which you agree not to make copies of the software to give away or for resale. FACTOID: < Show the students the software license for a Web browser. (For Internet Explorer, you can find this in the Help window. For Netscape Navigator, this can be found in the “About Communicator” page. The actual location on your computer may vary depending on which version of browser you are running.) Scroll down so that they can get an idea of the amount of “legalese” involved in a software license.> Pirated software - software obtained illegally, as when you make a copy of software that your friend has purchased. Discussion question: How serious an offense do you think it is to install software from a CD that your friend purchased and installed on his or her computer?
  • File - a named collection of (1) data or (2) a program that exists in a computer’s secondary storage. Document files - files created by word processing programs, which consist of documents such as reports, letters, memos, and term papers. Worksheet files - files created by electronic spreadsheets, which usually consist of collections of numerical data such as budgets, sales forecasts, and schedules. Database files - files created by database management programs, which consist of organized data that can be analyzed and displayed in various useful ways. Importing - getting data from another source and then converting it into a format compatible with the program in which you are currently working. Exporting - transforming data into a format that can be used in another program and then transmitting it to that program.
  • Office suite - several applications bundled together into a single large package, such as Microsoft Office, which includes: Word (word processing) Excel (spreadsheet) Access (database) PowerPoint (presentation graphics) FACTOID: Appleworks is the office suite provided with the Macintosh OS. Appleworks includes word-processing, spreadsheet, drawing, painting, database, and presentation applications. Groupware - online software that allows several people to collaborate on the same project. Discussion question: While computers can help us to work more efficiently, they can also be profoundly frustrating and unproductive. Have computers and IT really improved productivity?
  • GUI is pronounced as “gooey.” FACTOID: The Association for Computing Machinery ( ACM ) is the world’s first educational and scientific computing society. Founded in 1947, the ACM is organized into several SIGs—Special Interest Groups. One of these is called SIGCHI —Special Interest Group for Computer-Human Interaction. SIGCHI members are people working in the field of user interfaces.
  • Pop-up menu - a list of command options that can “pop up” anywhere on the screen when you click the menu button of your mouse. FACTOID: <Demonstrate a pop-up menu using the browser, by selecting the menu button on the mouse when the mouse is positioned over the background of a webpage.>
  • Taskbar - the toolbar graphic at the bottom of the screen, which shows the applications that are running in Microsoft Windows. FACTOID: Macintosh OS also has a graphic at the bottom of the screen. However, it is called a “Control Strip” as it contains many of the “Control Panels” used to change various settings of the computer and desktop. Window - a rectangular frame on the computer display screen, through which you can view a file of data or an application program. Do not confuse “windows” (multiple rectangular frames) with “Windows,” Microsoft’s operating system for PCs.
  • Word processing software - software which allows you to create, edit, format, print, and store text material, among other things.
  • Macro - a single keystroke or command--or a series of keystrokes or commands--used to automatically issue a longer, predetermined series of keystrokes or commands.
  • FACTOID: <Demo each of these operations using MS Word, Appleworks Word Processing, or whatever other word processing software may be present on the instructor’s computer.> Spelling checker - word processing feature which tests for incorrectly spelled words. Grammar checker - word processing feature which highlights poor grammar, wordiness, incomplete sentences, and awkward phrases. Thesaurus - word processing feature which presents you with the appropriate word or alternative words.
  • FACTOID: Your word processing software may provide a wizard feature but use a different name for it. For example, Microsoft Word has an “Office Assistant” instead of a wizard. Similarly, Appleworks provides “Assistants” rather than wizards. The concept is the same – only the name varies.
  • Two-column spacing used in many magazines and books. Many-column spacing used in newspapers. Justification - to align text evenly between left and right margins, as in most newspaper columns. Left-justification - to align text evenly on the left, leaving a “ragged-right” margin, as in business letters.
  • Header - common text (such as a date or document name) printed at the top of every page. Footer - the same thing printed at the bottom of every page. Clip art - collections of ready-made pictures and illustrations available online or on CD-ROM disks. Default settings - the settings automatically used by a program unless the user specifies otherwise, thereby overriding them. Saving - storing, or preserving, a document as an electronic file permanently.
  • Spreadsheet software - program which allows users to create tables and financial schedules by entering data and formulas into rows and columns arranged as a grid on a display screen. FACTOID: The two main players in the spreadsheet business are Microsoft Excel and IBM’s Lotus 1-2-3 . According to the U.S. Business Reporter , Excel has 65% of the market and Lotus 1-2-3 has 35%.
  • A cell pointer, or spreadsheet cursor, indicates where data is to be entered. FACTOID: When all 26 letters of the alphabet have been used up for column headings, spreadsheets start over with two-letter column headings, AA, AB, AC…AZ, BA, BB, BC…BZ, etc. Hence, a cell address of AB5 would be in the 5 th row and the 28 th column.
  • What-if analysis - allows the user to see how changing one or more numbers changes the outcome of the recalculation.
  • Redundancy - repetition of the same piece of information in several different files. Integrity - the accuracy and currency of the information. FACTOID: Many academic institutions offer certificate programs in various database topics. One example is UCD (University of California at Davis) Extension’s Certificate Program in Database Design, Development, and Management .
  • Relational database - the most widely used form of database on PCs, which organizes data into tables. FACTOID: MySQL is a very popular relational database management system. It is also an “open-source” program, which means that anyone can download and use it for free.
  • The most common key field in the U.S. is the Social Security number.
  • This lecture is being presented via presentation graphics software--namely, Microsoft PowerPoint. Well-known presentation graphics software: Microsoft PowerPoint Corel Presentations Lotus Freelance Graphics PowerPoint has several “views”: Slide View - for creating and modifying the slides themselves. Outline View - for entering text to be automatically formatted. Notes Page View - for entering text to be used as Speaker’s Notes. Sorter View - for viewing and reordering miniatures of each slide. Slide Show View - for viewing the slides as the audience will see them.
  • Personal-finance managers - let you keep track of income and expenses, write checks, do online banking, and plan financial goals. FACTOID: When the phrase “personal-finance software” is mentioned, most people immediately think of Quicken created by Intuit . Fortune magazine has named Intuit to its prestigious “100 Best Companies to Work For” list; Intuit is ranked 46 th .
  • Characteristics of DTP: Mix of text with graphics Varied type and layout styles Use of files from other programs
  • Vector image - image created from mathematical calculations. Raster image - image created from many little dots.
  • Web page design/authoring software - used to create web pages with sophisticated multimedia features. Video/audio editing software - allows you to modify a section of video, which is called a clip. Project management software - a program used to plan and schedule the people, costs, and resources required to complete a project on time. Computer-Aided Design (CAD) software - programs intended for the design of products, structures, civil engineering drawings, and maps. Computer-aided design/computer-aided manufacturing - software that allows products designed with CAD to be input into an automated manufacturing system that makes the products.
