Subject : it-skills
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 gearshift-like device used as a controller for arcade-style computer games.






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






3. 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.






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






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






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






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






8. 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.






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






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






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






12. 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.






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






14. 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.






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






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






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






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






19. 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.






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






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






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






23. 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.






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






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






26. See removable media.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






46. 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.






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






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






49. 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.






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