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 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.






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






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






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






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






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






7. 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.






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






9. 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.






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






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






12. 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






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






14. 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.






15. 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.






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






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






18. 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.






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






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






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






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






23. 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.






24. 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.






25. 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.






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






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






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






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






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






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






32. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






47. See removable media.






48. 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.






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






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