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






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






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






4. 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






5. 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.






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






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






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






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






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






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






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






13. 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.






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






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






16. 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.






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






18. 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.






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






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






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






22. 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.






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






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






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






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






27. 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.






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






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






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






31. 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.






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






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






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






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






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






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






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






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






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






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






42. 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.






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






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






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






48. See removable media.






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






50. 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.
