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. Storage device that uses magnetic tape to store information.






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






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






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






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






7. 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.






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






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






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






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






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






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






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






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






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






17. 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.






18. 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.






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






20. 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.






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






22. 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.






23. 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.






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






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






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






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






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






29. 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.






30. 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






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






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






33. 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.






34. See IEEE 1394.






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






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






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






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






39. 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.






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






41. 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.






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






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






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






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






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






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






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






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






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