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






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






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






4. 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.






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






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






7. See IEEE 1394.






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






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






10. 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






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






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






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






14. 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.






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






16. 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.






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






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






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






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






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






22. 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.






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






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






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






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






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






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






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






30. 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.






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






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






33. 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.






34. 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.






35. 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.






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






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






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






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






40. 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.






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






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






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






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






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






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






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






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






49. 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.






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