Usage Of Application Software

  1. 1. TASK 1: Usage of Application Software By: `Atikah Fatimah Hawa
  2. 2. The Application Software <ul><li>An application program (also called a software application or just an application) is software (usually provided by a vendor such as Microsoft , Inc.) that helps a user perform a specific kind of activity, such as word processing , graphic design , plotting data , playing a game, or anything else that can be done on a computer. The major kinds of application are: </li></ul><ul><li>~ Commercial applications </li></ul><ul><li>~ Shareware applications </li></ul><ul><li>~ Freeware applications </li></ul>
  3. 3. <ul><li>Of these, commercial applications, which the user must purchase the right to use, are the most important. Applications for common tasks such as word processing are almost always of this type. </li></ul><ul><li>The second type, shareware, includes applications usually created by single individuals or small groups of programmers working in their spare time. The user of such an application is on her or his honor to send its creator a small sum of money if they like the product and continue to use it. </li></ul>
  4. 4. Usage of Application Software <ul><li>Word processing and desktop publishing--manipulate text (including images embedded in text) in order to produce a document ready for printing or for electronic display. High-end applications of this class produce camera-ready copy, that is, pages that a printing company can print as-is and bind into a book, magazine, pamphlet, or the like. </li></ul><ul><li>Spreadsheet--perform computational tasks such as payroll, taxes, statistical analysis, etc. </li></ul><ul><li>Computer graphics and multimedia--create, view, or manipulate video or still images, sounds, etc. </li></ul><ul><li>Databases--store and retrieve information, for example household expenses, personal addresses, music collections, etc. </li></ul><ul><li>Telecommunications and networking--browse the Internet and </li></ul><ul><li>World Wide Web , exchange e-mail , etc. </li></ul>
  5. 5. <ul><li>It has become common for software vendors to sell several applications in a &quot;bundle&quot;--a number of applications bound up together in a single, unified software package. Such integrated applications are often cheaper than buying individual applications for different tasks, and they have the additional benefit of assured compatibility, because the vendor guarantees that the applications will all work smoothly together. </li></ul><ul><li>Application programs are specific to certain operating systems; that is, an application written to run under a specific operating system will not run under others. However, some vendors offer equivalent applications </li></ul><ul><li>that run under different systems. For example, nearly identical </li></ul><ul><li>versions of Microsoft Word are available for the Windows and </li></ul><ul><li>Macintosh operating systems. </li></ul>
  6. 6. <ul><li>Applications are sometimes confounded with operating systems, so we should note how the two both differ from and resemble each other. First, both are programs, that is, bodies of instructions that are copied into random-access memory for speedy execution and that manipulate information in the computer. </li></ul><ul><li>The operating system, however, has a unique status: it handles all the user's interactions with the computer itself (copying files, viewing directories, starting other programs, etc.). Running the operating system program is not optional; the user needs to run it to use the computer at all. This </li></ul><ul><li>is not true of any other program. Roughly speaking, </li></ul><ul><li>therefore, an application is any program that the user can </li></ul><ul><li>choose not to run. </li></ul>
  7. 7. <ul><li>Applications are entirely dependent upon the operating system to run properly, whereas the operating system may continue to run even if one or more applications fail. </li></ul><ul><li>Applications are usually &quot;quit&quot; or shut down after being used because computing resources (especially memory) are needed for other tasks; an operating system is only shut down when it is necessary to shut down the computer entirely or to reboot (i.e., to re-start the operating system due to a non-recoverable error). </li></ul>
  8. 8. <ul><li>That’s all.. </li></ul>
