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 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.






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






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






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






5. 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.






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






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






8. 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.






9. 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.






10. 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.






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






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






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






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






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






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






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






18. 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.






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






20. 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.






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. Storage device that uses magnetic tape to store information.






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






24. 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.






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






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






27. See removable media.






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






29. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






44. 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.






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






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






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






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






49. 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.






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