Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. A disk drive that uses laser beams to read and write bits of information on the surface of an optical disk.






2. Locating and identifying printed characters embedded in an image - allowing the text to be stored as an editable document. OCR can be performed by wand readers - pen scanners - and OCR software.






3. A pressure-sensitive touch tablet used as a pointing device. The user presses on the tablet with a stylus.






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






5. Hardware peripheral that enables a computer to send onscreen documents to a receiving fax machine by translating the document into signals that can be sent over phone wires and decoded by the receiving fax machine.






6. A reading tool that uses light to read universal product codes - inventory codes - and other codes created out of patterns of variable-width bars.






7. Television-style monitors used as the output device for many desktop computers.






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






9. 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.






10. A type of erasable memory chip used in cell phones - pagers - portable computers - and handheld computers - among other things.






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






12. See removable media.






13. An output device capable of sending - in effect - a photocopy through a telephone line - allowing for fast and convenient transmission of information stored on paper.






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






15. To remove and replace peripheral devices without powering down the computer and peripherals. Some modern interface standards such as USB and FireWire allow hot-swapping.






16. Flat-panels displays - once primarily used for portable computers but now replacing bulkier CRT monitors for desktops.






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






18. Compact disk-recordable - an optical disk you can write information on - but you cannot remove the information.






19. Compact disk-rewritable - an optical disk that allows writing - erasing - and rewriting.






20. Converting information into a digital form that can be stored in the computer's memory.






21. The science of designing work environments that enable people and things to interact efficiently and safely.






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






23. Storage device that uses magnetic tape to store information.






24. A nonimpact printer that uses a laser beam to create patterns of electrical charges on a rotating drum. The charged patterns attract black toner and transfer it to paper as the drum rotates.






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






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






27. 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.






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






29. Pointing device that responds when the user points to or touches different screen regions.






30. A type of newer inkjet printer specially optimized to print high-quality photos captured with digital cameras and scanners.






31. An input device that makes a digital representation of any printed image. See flatbed scanners - slide scanners - drum scanners - and sheetfed scanners.






32. An impact printer used by mainframes to produce massive printouts. They print characters only - not graphics.






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






34. 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






35. A gearshift-like device used as a controller for arcade-style computer games.






36. An output device that displays text and graphics onscreen.






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






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






39. 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.






40. Storage - such as flash memory - with no moving parts. Solid-state storage is likely to replace disk storage in the future.






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






42. Storage method that requires the user to retrieve information by zipping through it in the order in which it was recorded.






43. A reading tool that uses radio waves to communicate with RFID tags.






44. 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.






45. Long-term repository for data. Disks and tape drives are examples.






46. Input device - similar to a typewriter keyboard - for entering data and commands into the computer.






47. A terminal with a wand reader - barcode scanner - or other device that captures information at the check-out counter of a store.






48. A common optical drive in computers that can read data from CD-ROM disks.






49. A camera that captures images and stores them as bit patterns on disks or other digital storage media instead of using film.






50. Software that translates the user's handwritten forms into ASCII characters.
