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 allows information retrieval without regard to the order in which it was recorded.






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






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






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






5. See IEEE 1394.






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






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






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






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






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






12. 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.






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






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






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






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






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






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






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






20. 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.






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






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






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






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






25. 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.






26. 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.






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






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






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






30. See removable media.






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






32. 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.






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






34. 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






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






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






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






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






39. 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.






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






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






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






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






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






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






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






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






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






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