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






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






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






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






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






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






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






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






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






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






11. 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.






12. 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.






13. 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.






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. 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






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






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






18. 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.






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






20. 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.






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






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






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






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






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






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






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






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






29. 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.






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






31. See IEEE 1394.






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






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






34. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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