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






2. See removable media.






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






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






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






6. 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.






7. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






22. 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.






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






24. See IEEE 1394.






25. 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.






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






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






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






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






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






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






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






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






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






36. 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.






37. 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






38. 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.






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






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






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






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






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






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






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






46. 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.






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






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






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






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