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






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






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






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






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






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






8. 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.






9. 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.






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






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






12. 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.






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






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






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






16. 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.






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






18. 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.






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






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






21. 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.






22. 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






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. 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.






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






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






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






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






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






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






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






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






34. See IEEE 1394.






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






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






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






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






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






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






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






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






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






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






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






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






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






48. 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.






49. 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.






50. See removable media.
