  1. 1. Nick Gorton Jace Sadowsky
  2. 2.  How data is received into a computer system, and how information and the results of processing are provided to the user from a computer system.
  3. 3.  Used for taking data and entering it into a computer system.  Different types of input devices are designed to accept different types of data.  2 types of data are human readable data and machine readable data.
  4. 4.  Automating data entry where the data is created, thus ensuring accuracy and timeliness.  Used by librarians, many rental car companies and other professionals.  Used to scan books and cars to collect data.
  5. 5.  A device that is made to be used for a variety of computing activities.  Keyboards, pointers, touch screens, multi- touch displays and microphones are general purpose input devices.
  6. 6.  Provide data input for one specific type of activity.  Game controllers, joysticks, webcams, page scanners and handheld scanners are special purpose input devices.
  7. 7.  Businesses and organizations use special- purpose scanners and optical readers to collect data.  Card swipers are another way of collecting data into a computer.  Card swipers are used to verify the identity of individuals wishing to access secure locations.
  8. 8.  Allows a user to see the results of computer processing with one or more senses.  Good output devices deliver information in a manner that allows the information to be interpreted easily.
  9. 9.  Computer output consists of data results that are observable by human senses or that can be used as input into another system.  For example, iPod users synchronize music from their computer to the iPod, with the output of the computer acting as input for the iPod.
  10. 10. VISUAL AUDIO • Monitors • Printed Documents  Speakers  Headphones
  11. 11.  Combine video processing and storage onto an expansion card or onto the motherboard to manage video images for display.  Video cards provide important capabilities for today’s graphics-intensive software.  Also known as graphics cards.
  12. 12.  Video cards manage all images sent to a computer’s display.  Devices that use video cards include:  Microsoft Windows Vista  Mac OS X  3D computer games
  13. 13.  Provides visual computer output on a monitor or screen.  The most common form of computer output is visual on a display
  14. 14.  Cathode Ray Tube (CRT)  Older, bulkier televisions  Liquid Crystal Display (LCD)  Thin flat display using liquid crystals  Plasma Display  plasma gas between two flat panels to excite phosphors and create light
  15. 15.  Light Emitting Diode (LED)  utilize LEDs to provide the backlight for the display rather than the fluorescent light used in traditional LCDs.  Electronic Paper  uses pixels made of particles or oils that reflect light to resemble the pages of a book.
  16. 16.  provides a specific type of computer output on paper or three-dimensional output in plastic.  The different types of printers are  Laser  Ink-jet  Photo  Multifunction  Plotters  3D Printers
  17. 17.  Provide output to senses other than sight.  Sound is used by the computer operating system and other software to make the user aware of certain events.
  18. 18.  Computer’s capacity to interface with external devices by connecting through ports, slots, and wireless technologies.  Expansion allows computer users to enjoy benefits beyond those provided by the computer alone.
  19. 19.  Scanners  Webcams  Keyboards
  20. 20.  Any Questions?
