Understanding Computer Software: Types, Functions, and Development Process

DESCRIPTION

Computer software is essential to operate hardware and perform various tasks. It includes applications, system software, and language translators, which help convert code into a language the computer understands. Significant figures like Grace Hopper, who developed COBOL, contributed to this field, which is multi-step and complex. Operating systems like Windows, MacOS, and Unix serve as the interface between users and computers. Additionally, utility software assists with housekeeping tasks. Understanding software is crucial for maximizing computer functionality.

  1. What is Computer Software?

  2. Hardware vs Software Got to have both to get the job done!

  3. How does Software work? • Algorithms have to be written • Algorithm turned into computer language • Another specialized program turned this language into something the computer understands • Software development – multi-step process • First programmer – Grace Hooper – created FLOW MATIC (later known as – COBOL)

  4. Types of Software • Applications Software • Systems Software • Operating systems • Utilities • Language translators

  5. Applications Software

  6. Operating Systems • Interface between user and the computer • Many brands • Windows – designed for processor Intel • Apple – Mac OS, IOS

  7. Utility Software • Helps perform housekeeping chores • Tasks include: • Antivirus programs • Copy file from hard drive to another location • Convert graphics file so it can be used by another program • Backup copy of hard drive

  8. Language Translators • Converts code written in English to a language the computer can understand • Translator helps computer process data I don’t understand! I need a translator.

  9. Operating Systems • Mac OS • DOS • Windows • Unix – portable operating system (can run on just about any hardware platform) • Networking Operating System – group of two or more computers to be connected • Window NT • Novell’s Netware • IBM’s Warp Server

  10. Operating Systems Statistics • http://www.w3schools.com/browsers/browsers_os.asp

  11. User Interfaces • Determines how user friendly the computer is • Part we interact with when using the computer • Command-line interface such as DOS • Graphical interfaces such as Windows

  12. Command Line • Early computers used only this • Have to memorize codes • Not very user friendly • Not colorful – usually written in black and white • No pictures

  13. Graphical User interfaces • Came about with menus • Graphical user interface (GUI) • Came about with Apple’s development of Macintosh Finder • Pictures (icons) represent software • Colorful • Contributed to the explosion of computer use.

  14. Project • See website for assignment
