1 Computers Tools for an Information Age
Chapter 2 Applications Software: Getting the Work Done

2 Objectives Distinguish between operating systems and applications software List the various methods by which individuals and businesses acquire software List and briefly describe various types of task-oriented software Identify the kinds of software that are available for both large and small businesses Discuss ethical issues associated with software Describe the functions of various computer professionals

3 Applications Software
Software used to solve a particular problem or perform a particular task

4 Acquiring Software: Traditional Ways
Custom software Written by programmers hired by organization Packaged (commercial) software Purchased from a store, catalog, or Web site

5 Custom Software Specifically tailored to an organization’s needs
Organization hires computer programmers to design, write, test, and implement software Can be extremely complex and take years to write Return

6 Packaged Software Sold in stores, catalogs, or Web sites
Sometimes downloaded from the Internet Package contains one or more CDs or DVDs holding the software Typically contains software documentation Designed to be user-friendly Return

7 User-Friendly Software
Easy to use Should be intuitive for even a beginning user Can be used with minimum of training and documentation Return

8 Acquiring Software: New Ways
Open-Source Software Shareware Freeware Public Domain Software

9 Freeware Author provides it free for all to use
Author retains copyright May place restrictions on its use May not be altered or redistributed without permission Return

10 Public Domain Software
Software that is not copyrighted May be used and even altered without permission Typically developed by universities and/or research institutions using government grants Return

11 Open-Source Software A variation of freeware
Source code made available Source code: readable by humans Other programmers can modify and redistribute the programs freely Helps identify bugs and create improvements more easily Return

12 Shareware Copyrighted software, freely distributed for a trial period
If you like it, register it for a fee Most authors add free documentation, enhancements, support, and updates to encourage people to register Return

13 Buying Commercial Software
Individual copies for each computer Site license Electronic software distribution Application Service Provider

14 Site License Software installed on some or all computers, depending on license terms Customer keeps track of how many users Number of users cannot exceed number of licenses Customer copies and distributes software and manuals to users Some organizations use network licenses Software installed on server License fee based on number of concurrent users Return

15 Electronic Software Distribution
Get software from the Internet Typically freeware and shareware Some commercial software Typical scenario: Download software for trial period Software disables itself after trial period unless you register (pay) Return

16 Application Service Provider
Delivers applications to businesses via the Internet ASP maintains software and data on its systems Customers access applications as needed over the Internet Alternative to creating and maintaining custom software or purchasing packaged software “Rent” software, paying based on usage Return

17 Task-Oriented Software
Often called productivity software Common categories Word processing/Desktop publishing Electronic spreadsheets Database management Graphics Communications Others

18 Working with Words Word Processing Desktop Publishing
Most widely used personal computer software Create memos, reports, papers Incorporate graphics into documents Desktop Publishing High-level publishing needs Newsletters Brochures, promotional materials Return

19 Electronic Spreadsheets
Made up of rows and columns of numbers Perform “what if” analysis Change a cell and have spreadsheet recalculate Present data graphically Show expenses as a pie chart Return

20 Database Management Handles the management of a collection of interrelated facts Software can store, retrieve, update, and manipulate data Can report data in many ways and print Turn large amounts of data into information Return

21 Graphics Graphics software creates graphs and charts from numeric data
Spot trends and compare data more easily Visual evidence more compelling Included in spreadsheet programs Presentation graphics creates “slide show” presentations Combine high-quality graphics, audio, and video Return

22 Communications The ability to hook the computer up to phone line or cable and communicate with another computer Typically connected over the Internet Needs a browser to access other locations on the Internet Return

23 Other Task Software Personal Information Managers Office Suite
Keep track of activities Typically include appointment calendar, address book, and task manager Office Suite A group of basic applications that work together Easy to share data among applications Similar look and feel among applications Integrated application A “stripped down” version of the office suite, e.g. Microsoft Works Return

24 Business Software Vertical Market software Software for Workgroups
Small Business software

25 Vertical Market Software
Written for a particular type of business Written by companies who have a thorough knowledge of that industry Allows business to easily maintain information on the business, customers, vendors Encompasses all of the business’s activities Return

26 Groupware Lets a group of people share or track information together
Also called collaborative software Often combines electronic mail, networking, scheduling, and database technology Data stored in one central location Often used by organizations with remote employees Return

27 Software for a Small Business
Small Office/Home Office (SOHO) Moderately priced software to perform functions aimed at small business Examples: Accounting software Writing and advertising Customer service Keeping contacts Making sales pitches Return

28 Ethics and Application Software
Piracy: the acquisition and use of illegal copies of software Counterfeiting: copying large numbers of CD-ROMs or DVD-ROMs and packaging them to look like the real thing Unauthorized copying of software is stealing

29 Software Piracy Examples of piracy
Copying software from a lab or from a friend Buying 2 or 3 copies of software and distributing it to dozens or hundreds of employees Buying 1 copy of software and installing it on several computers at home

30 Computers and People Most organizations have some sort of information technology department Made up of people who are responsible for the organization’s computer resources Maintain data and provide services to end users

31 Computer People Data entry operators prepare data for processing
Computer operators monitor systems, keep peripherals running, and make backups Librarians catalog processed disks and tapes Programmers design, write, test, implement, and maintain computer programs

32 Computer People Systems analysts plan and design entire systems
Must have knowledge in programming, as well as knowledge of the business Network managers implement and maintain organization’s network(s) Chief Information Officer (CIO) makes key technology decisions A key member of the organization’s strategic decision-making team
