  • 1. Keyboarding Concepts Dale Gunter Forestview High School
  • 2. Objective:
    • Describe the purpose, components, and use of computer hardware and software.
  • 3. Components of an Information System
    • Hardware
    • The ‘physical’, tangible parts of the computer system.
    • This includes monitors, disk drives, cables, printers, keyboards, scanners, microphones, speakers, modems, etc.
  • 4. Components of an Information System
    • Applications Software
    • Computer programs designed to perform specific functions….
    • Word-processing, database, and spreadsheet software are examples of applications software.
  • 5. Components of an Information System
    • Systems Software
    • Computer programs designed to run the actual computer when it is turned on.
      • Examples are MS-Dos, Windows 95, Windows 98.
  • 6. Applications Software
      • Word Processing
      • Used to create documents such as letters, reports, memos, and flyers.
      • Word processors perform work that was originally done on the typewriter.
  • 7. Applications Software
      • Spreadsheet
      • Used to process numerical information.
      • Spreadsheets are used to process financial and statistical calculations.
      • Spreadsheets consist of rows and columns and are widely used in accounting.

  • 11. Definitions of Hardware Types
      • Four main types of hardware make up the computer system
      • 1. Input devices
      • 2. Processor
      • 3. Storage
      • 4. Output Devices
  • 12. Definitions of Hardware Types
      • Input Devices
      • Used to enter information into the computer.
      • Examples are keyboard, joystick, mouse, scanner, voice recognition device, touch screen, microphone and light pen.
  • 13. Definitions of Hardware Types
      • Processor
      • The device or microcircuits that manipulates data and receives and carries out instructions.
      • The processor is the ‘brains’ of the computer
  • 14. Definitions of Hardware Types
    • Storage
    • Devices that save data so that it can be used again.
    • Disk drives are used to store data on disks
    • Storage capacity is measured in megabytes and gigabytes.
  • 15. Definitions of Hardware Types
    • Output Device
    • Displays or prints information produced by the computer.
    • Printers and monitors are examples are examples of output devices.
  • 16. Definitions of Hardware Types
    • Output Devices
    • A Printer produces ‘hard’ copy output
    • A Monitor produces ‘soft’ copy output
  • 17.
    • System Schematic
    Hardware Diagram Input Processor Output Storage
  • 18. Input Devices
  • 19. Storage Devices
  • 20. Output Devices
  • 21. Printers
    • Impact Printers-a printer that strikes the paper in order to form images.
      • Example: Dot Matrix Printer
    • Non-Impact Printers-a printer that forms images without striking the paper.
      • Example Laser or Inkjet printers
  • 22. Computer Care
    • Keep food and drinks away from the computer and keyboard.
    • Avoid dusty locations.
    • Avoid bright sunny locations.
    • Do not move the computer while it is in use.
    • Always exit programs per user manual instructions.
