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 radio waves to communicate with RFID tags.






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






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






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






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






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






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






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






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






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






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






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






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






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






16. 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.






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






18. 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.






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






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






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






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






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






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






25. 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.






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






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






28. 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.






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






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






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






32. See removable media.






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






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






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






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






37. 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.






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






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






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






41. 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.






42. 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.






43. 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.






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






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






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






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






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






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






50. 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.
