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






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






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






4. 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.






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






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






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






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






9. 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.






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






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






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






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






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






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






16. 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.






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






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






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






20. 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






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






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






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






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






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






26. 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.






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






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






29. 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.






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






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






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






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






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






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






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






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






38. 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.






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






40. 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.






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






42. See removable media.






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






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






45. 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.






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






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






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






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






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