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. 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.






2. 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.






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






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






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






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






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






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






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






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






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






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






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






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






15. See removable media.






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






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






18. 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.






19. 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.






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






21. 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.






22. See IEEE 1394.






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






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






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






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






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






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






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






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






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






32. 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.






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






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






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






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






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






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






40. 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.






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






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






43. 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.






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






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






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






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






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






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






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.
