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






2. 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






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






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






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






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






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






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






9. See removable media.






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






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






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






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






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






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






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






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






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






19. 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.






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






21. 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.






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






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






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






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






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






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






28. 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.






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






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






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






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






33. 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.






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






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






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






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






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






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






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






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






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






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






45. 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.






46. See IEEE 1394.






47. 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.






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






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






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