  2. 2. Software It means computer instructions or data. Anything that can be stored electronically is software.
  3. 3. Difference of a Software Engineer from a Programmer While a programmer creates the codes that make a program run, a software engineer creates the designs the programmer implements.
  4. 4. Categories of Software Software is often divided into two categories : Operating System  Application Software
  5. 5. Operating System The Operating System is the most important program that runs on a computer. Every general-purpose computer must have an operating system to run other programs.
  6. 6. Operating System Without a computer operating system, a computer and software programs would be useless.
  7. 7. Operating System
  8. 8. Operating System Types  GUI –Graphical User Interface  Multi-user  Multiprocessing  Multitasking  Multithreading
  9. 9. Graphical User Interface A GUI Operating System contains graphics and icons and is commonly navigated by using a computer mouse. Example : System7.x,Windows98,
  10. 10. Multi-user A multi-user operating system allows for multiple users to use the same computer at the same time and different times. Example :Linux, Windows 2000,
  11. 11. Multiprocessing An operating system capable of supporting and utilizing more than one computer processor. Example :Linux, Windows 2000,
  12. 12. Multitasking An operating system that is capable of allowing multiple software processes to run at the same time. Example :Unix, Windows 2000
  13. 13. Multithreading Operating systems that allow different parts of a software program to run concurrently. Example :Linux, Windows 2000, Unix
  14. 14. Operating System
  15. 15. Basic Tasks of an Operating System Recognizing input from the keyboard Sending output to the display screen Keeping track of files and directories on the disk Controlling peripheral devices
  16. 16. Applications Software It is also called end- user programs. It includes programs that do real work for users. It is the general designation of computer programs for performing user tasks.
  17. 17. Applications Software Figuratively speaking, applications software sits on top of systems software because it is unable to run without the operating system
  18. 18. A layer structure showing where the operating system software and application software are situated while running on a typical desktop computer Operating System and Application Software
  19. 19. Programs of an Applications Software Database Programs Games Web Browsers  Word Processing Spreadsheets
  20. 20. Categories of an Application Software  Vertical Application-designed for a particular type of organization.  Horizontal Application- are the most popular and widespread in departments or companies.
  21. 21. Conclusion The operating system itself can be considered application software when performing simple calculating, measuring, rendering, and word processing tasks that not used to control hardware via command- line interface or graphical user interface. This does not include application software bundled within operating systems such as a software calculator or text editor.
