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






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






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






4. 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.






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






6. 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.






7. 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.






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






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






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






11. A type of optical disk with multigigabyte capacity that can be read - written - and erased.






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






13. A disk drive that uses laser beams to read and write bits of information on the surface of an optical disk.






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






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






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






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






18. 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.






19. 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.






20. A rigid - magnetically sensitive disk that spins rapidly and continuously inside the computer chassis or in a separate box attached to the computer housing. Used as a storage device.






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






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






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






24. A nonimpact printer that sprays ink directly onto paper to produce printed text and graphic images.






25. Standards for ports and other connective technology agreed upon by the hardware industry so that devices made by one manufacturer can be attached to systems made by other companies.






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






27. 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.






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






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






30. Storage medium with random-access capability - accessed by the computer's disk drive.






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






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






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






34. 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.






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






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






37. 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.






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






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






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






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






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






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






44. See IEEE 1394.






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






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






47. See removable media.






48. Compact disc-read-only memory - a type of optical disk that contains data that cannot be changed; CD-ROMs are commonly used to distribute commercial software programs.






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






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