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 printer that produces characters without physically striking the page.






2. 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.






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






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






5. 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.






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






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






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






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






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






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






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






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






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






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






16. 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.






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






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






19. See removable media.






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






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






22. 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.






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






24. 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.






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






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






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






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






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






30. 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.






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






32. 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






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






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






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






36. 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.






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






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






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






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






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






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






43. 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.






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






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






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






47. 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.






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






49. 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.






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