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






2. 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.






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






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






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






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






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






8. 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.






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






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






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






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






13. 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.






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






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






16. 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.






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






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






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






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






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






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






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






25. 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.






26. 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.






27. 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.






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






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






30. 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.






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






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






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






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






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






36. 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






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






38. 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.






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






40. See removable media.






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






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






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






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






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






46. 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.






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






48. See IEEE 1394.






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






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