7 General-Purpose Applications Application software is any program that gives the user the ability to complete work on the computer. General-purpose applications, such as word-processing or spreadsheet programs, enable users to complete common tasks. Copyright 2011 Pearson Education, Inc. Publishing as Prentice Hall 7

8 General-Purpose Applications Types of general-purpose application software Personal productivity programs Multimedia and graphics software Applications that work through and run from the Internet Home and education programs Copyright 2011 Pearson Education, Inc. Publishing as Prentice Hall 8

9 General-Purpose Applications Personal productivity programs Make it easier to do work Examples Word-processing software Spreadsheet or database software Presentation software Copyright 2011 Pearson Education, Inc. Publishing as Prentice Hall 9

10 General-Purpose Applications Multimedia and graphics software includes the use of two or more media, such as graphics plus video or audio. Copyright 2011 Pearson Education, Inc. Publishing as Prentice Hall 10

11 General-Purpose Applications Multimedia and graphics software programs Professional desktop publishing Multimedia authoring Paint, drawing, and animation Image editing 3D rendering Audio Video editing Copyright 2011 Pearson Education, Inc. Publishing as Prentice Hall 11

12 General-Purpose Applications Codecs are algorithms that reduce file size and allow faster Internet transfer speeds. Lossless compression does not delete any information needed to reproduce the image without flaw. Lossy compression removes some information, but the loss is typically not noticeable. Copyright 2011 Pearson Education, Inc. Publishing as Prentice Hall 12

13 General-Purpose Applications Use paint programs to create bitmapped images (raster graphics), which are made up of tiny dots known as pixels. Copyright 2011 Pearson Education, Inc. Publishing as Prentice Hall 13

14 General-Purpose Applications Paint program standard file formats Graphics Interchange Format (GIF) Lossless compression of simple images Often used for Web pages Joint Photographic Experts Group (JPEG) Lossy compression of complex images Also used for Web pages Copyright 2011 Pearson Education, Inc. Publishing as Prentice Hall 14

15 General-Purpose Applications Portable Network Graphics (PNG) Patent-free alternative to a GIF Lossless compression, suitable for Web use only Windows Bitmap (BMP) Compression optional Files tend to be large Tag Image File Format (TIFF) Includes descriptive information with the image Used in publishing Copyright 2011 Pearson Education, Inc. Publishing as Prentice Hall 15

16 General-Purpose Applications Drawing programs create vector graphics that can be edited and resized without distortion. Copyright 2011 Pearson Education, Inc. Publishing as Prentice Hall 16

17 General-Purpose Applications Three-dimensional rendering programs provide graphic objects with 3D effects. Image editors Are advanced types of paint programs Can change complicated bitmapped objects, including photographs Can edit, but not create, bitmapped images Copyright 2011 Pearson Education, Inc. Publishing as Prentice Hall 17

18 General-Purpose Applications Animation programs give the user the ability to create animation from images and run the animation. Copyright 2011 Pearson Education, Inc. Publishing as Prentice Hall 18

19 General-Purpose Applications Audio software is used to capture and process sound used in multimedia presentations. Copyright 2011 Pearson Education, Inc. Publishing as Prentice Hall 19

20 General-Purpose Applications Standard sound file formats MP3 Windows Media Audio (WMA) WAV Ogg Vorbis Musical Instrument Digital Interface (MIDI) Copyright 2011 Pearson Education, Inc. Publishing as Prentice Hall 20

21 General-Purpose Applications Video editors enable the user to: Modify digitized videos. Save those videos in at least one of the following video file formats: Moving Picture Experts Group (MPEG) QuickTime Video for Windows Copyright 2011 Pearson Education, Inc. Publishing as Prentice Hall 21

22 General-Purpose Applications Multimedia authoring systems Used to create multimedia presentations Require a large amount of disk space and memory to run properly Copyright 2011 Pearson Education, Inc. Publishing as Prentice Hall 22

23 General-Purpose Applications Applications that work through the Internet Examples Instant messaging software Web browsers Video conferencing programs Copyright 2011 Pearson Education, Inc. Publishing as Prentice Hall 23

24 General-Purpose Applications Web-hosted technology Share files and collaborate. Windows Office Live Google Docs Help avoid file incompatibility. Undesirable Internet software Spyware monitors your activity. Adware targets products to your interests. Copyright 2011 Pearson Education, Inc. Publishing as Prentice Hall 24

25 General-Purpose Applications Home and educational programs Computerized reference software Multimedia dictionaries Encyclopedias How-to guides Personal finance software Computer games Copyright 2011 Pearson Education, Inc. Publishing as Prentice Hall 25

26 Tailor-Made Applications Software designed for specific businesses or users are known as tailor-made applications. Tailor-made applications normally cost more than general-purpose applications because of their development costs. Copyright 2011 Pearson Education, Inc. Publishing as Prentice Hall 26

27 Tailor-Made Applications Custom software, developed for a user s specific needs, may be necessary when an application is not available. Packaged software is developed for the mass market. Copyright 2011 Pearson Education, Inc. Publishing as Prentice Hall 27

28 Standalone Programs, Integrated Programs, & Software Suites A fully self-contained program is called a standalone program. Advantages Purchased and installed separately Function by themselves Disadvantages Take a lot of storage space Do not share resources Copyright 2011 Pearson Education, Inc. Publishing as Prentice Hall 28

29 Standalone Programs, Integrated Programs, & Software Suites Integrated programs provide leading productivity programs in one package. Easy to learn and share the same interface Example: Microsoft Works Have fewer features than standalone programs and software suites Copyright 2011 Pearson Education, Inc. Publishing as Prentice Hall 29

30 Standalone Programs, Integrated Programs, & Software Suites A software suite (office suite) is a bundle of standalone programs.

Publishing as Prentice Hall 33

34 System Requirements & Software Versions Documentation may be in print or downloaded from the Internet. Brief tutorials Read Me files Help files Copyright 2011 Pearson Education, Inc. Publishing as Prentice Hall 34

35 Software Licenses & Registration A contract included with purchased software that permits the user to install the program on one computer is known as a software license. A contract that gives organizations the right to install copies of programs on a precise number of computers is known as a site license. Copyright 2011 Pearson Education, Inc. Publishing as Prentice Hall 35

36 Software Licenses & Registration Commercial Software Users must purchase before using Examples Microsoft Office Adobe Acrobat Apple ilife Shareware You may try software before purchasing it.

Publishing as Prentice Hall 37

38 Installing & Managing Application Software Installing software on a computer involves moving the software to the hard disk and properly configuring the software. Uninstalling software takes the program off the hard disk. Launching software moves it from the hard disk to memory. Copyright 2011 Pearson Education, Inc. Publishing as Prentice Hall 38

39 Installing & Managing Application Software Users can choose options to identify how they want a program to run. Defaults are software settings used by the program unless overridden by the user. Quitting or closing down an application is known as exiting. Copyright 2011 Pearson Education, Inc. Publishing as Prentice Hall 39

40 Summary System software supports application software, the programs that give the user the ability to complete work on the computer.
