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. 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.






2. 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.






3. 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.






4. 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.






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






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






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






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






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






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






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






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






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






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






15. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






31. 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.






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






33. See IEEE 1394.






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






35. 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.






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






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






38. 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.






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






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






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






42. 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.






43. 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






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






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






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






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






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






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






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