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. 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.






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






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






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






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






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






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






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






9. 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.






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






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






12. 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.






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






14. See removable media.






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






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






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






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






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






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






21. 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.






22. 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.






23. 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.






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






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






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






28. 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.






29. 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.






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






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






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






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






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






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






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






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






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






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






40. 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.






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






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






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






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






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






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






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






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






49. See IEEE 1394.






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