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






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






3. 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.






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






5. 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.






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






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






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






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






10. 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.






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






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






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






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






15. 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.






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






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






18. 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.






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






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






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






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






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






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






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






26. 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.






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






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






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






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






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






33. 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.






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






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






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






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






38. 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.






39. 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






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






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






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






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






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






45. 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.






46. 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.






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






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






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






50. See IEEE 1394.
