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






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






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






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






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






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






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






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






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






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






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






12. 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.






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






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






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






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






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






18. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






40. See IEEE 1394.






41. 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






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






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






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






45. 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.






46. 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.






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






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






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






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.
