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 radio waves to communicate with RFID tags.






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






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






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






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






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






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






8. 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.






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






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






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






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






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






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






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






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






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






18. See removable media.






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






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






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






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






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






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






25. 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.






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






27. 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.






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






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






30. 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.






31. 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.






32. 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






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






34. 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.






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






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






37. See IEEE 1394.






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






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






40. 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.






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






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






43. 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.






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






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






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






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






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






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






50. 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.
