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






2. 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.






3. 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.






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






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






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






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






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






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






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






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






12. See IEEE 1394.






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






14. 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.






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






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






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






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






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






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






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






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






23. 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.






24. 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






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






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






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






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






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






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






31. 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.






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






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






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






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






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






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






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






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






40. 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.






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






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






43. 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.






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






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






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






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






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






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






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