Chapter 8a: Software - Word Processing Goals In this chapter you will learn about the main categories of software and the most common applications. Applications are defined and classified in terms of their scope and uses. The chapter then turns to giving general concepts about word-processing, spreadsheet, and database software. The reader should review this chapter in conjunction with Workshops 3 7. Whereas workshops focus on the practical and procedural aspects of using applications, this chapter provides a more global approach to the functions served by the applications covered in the workshops. Application Software In contrast to system software, which runs the machine, application software performs tasks that are directly useful to the user. Thus, it is sometimes called personal productivity software. Application software can be classified into horizontal or vertical applications. Horizontal applications are used across the functional divisions of an organization and are really good at performing one task or one kind of tasks. Word processing software and spreadsheets are examples of horizontal applications. Vertical applications are useful at many functional levels within a single enterprise. They are really good at integrating all functions into a single coherent unit that can be tailored to the enterprise. Software used in a dentist’s office is an example of vertical application. The application is used to enter, manage, and archive all transactions and patient’s records. It handles appointments, acquisition, storage and display of X-rays, payroll, etc. Applications should drive the selection of computer systems, because only those computers that can run the necessary applications efficiently will achieve the goals behind the purchase of hardware. Conversely, selecting appropriate software requires consideration of whether it will be compatible with hardware you already own or plan to buy. S OFTWARE C OPYRIGHT C ATEGORIES There are four categories of software in relation to the right to use, modify, and or sell it: commercial, shareware, freeware, and public domain. Commercial software is copyrighted so it cannot legally be used in any ways other than those spelled out in its license and by the owner of the license. Violating this license is a crime called software piracy. The result of software piracy is higher software

8a-2 Software-Word Processing prices for everyone. Shareware and freeware programs are also copyrighted and licensed, but shareware allo ws a “try before you buy” limited period of free use, while freeware costs nothing to license. The “free” in freeware refers only to price. Like commercial programs, shareware and freeware can usually be registered, and should be. It is important to understand the difference between price of software and copyright. Regardless of price, the use and distribution of software may be limited by a copyright and license terms and conditions. Thus, freeware does not cost anything, but
