25 Questions

1. Printer that forms images by physically striking paper - ribbon - and print hammer together.

2. A handheld input device that - when moved around on a desktop or table - moves a pointer around the computer screen.

3. A keyboard that places the keys at angles that allow your wrists to assume a more natural position while you type - potentially reducing the risk of repetitive-stress injuries.

4. Pointing device that remains stationary while the user moves a protruding ball to control the pointer on the screen.

5. A circuit board that allows the PC to accept microphone input - play music and other sound through speakers or headphones - and process sound in a variety of ways.

6. A reading device that uses reflected light to determine the location of pencil marks on standardized test answer sheets and similar forms.

7. A device that enables digital machines to monitor a physical quantity of the analog world - such as temperature - humidity - or pressure - to provide data used in robotics - environmental climate control - and other applications.

8. An optical disk drive that can read high-capacity DVD disks.

9. A storage medium used with a tape drive to store large amounts of information in a small space at relatively low cost.

10. Output device that produces a paper copy of any information that can be displayed on the screen.

11. An all-in-one output device that usually combines a scanner - a laser or inkjet printer - and a fax modem.

12. A printer that produces characters without physically striking the page.

13. A tiny joystick-like device embedded in the keyboard of a laptop computer.

14. A device that - when energized by a nearby RFID reader - broadcasts information to the reader for input into a computer.

15. Storage method that allows information retrieval without regard to the order in which it was recorded.

16. A disk drive that can read and write on rewritable optical disks.

17. Conditions that result from repeating the same movements over long periods - such as keyboarding-induced carpal tunnel syndrome - a painful affliction of the wrist and hand.

18. A small flat-panel pointing device that is sensitive to light pressure. The user moves the pointer by dragging a finger across the pad.

19. A keyboardless machine that accepts input from a stylus applied directly to a flat-panel screen.

20. A data path standard that theoretically allows up to 126 devices - such as keyboards - digital cameras - and scanners - to be chained together from a single port - allowing for data transmission that is much faster and more flexible than through trad

21. An automated drawing tool that produces finely scaled drawings by moving pen and/or paper in response to computer commands.

22. A type of impact printer - which forms images by physically striking paper - ribbon - and print hammer together - the way a typewriter does.

23. A device that reads numbers printed with magnetic ink on checks.

24. Density of pixels - measured by the number of dots per inch.

25. Small - magnetically sensitive - flexible plastic wafers housed in a plastic case - used as a storage device.
