CWNA Vocab

Subjects : cisco, it-skills, cwna
Instructions:
  • Answer 24 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. In terms of CWNA it means the loss of signal strength.






2. Shape and form of the AC signal






3. Is an alternating current (AC)that continuously chaanges b/wa possitive and negative voltage.






4. The fluctuation of voltagein an AC current - AKA Cycling. Single change from up to down -or from positive to negative to positive.






5. A modulated signal that is capable of distinguishing between 0s and 1s






6. The distance that a single cycle RF wave travels.






7. Developed Open Systems Interconnection (OSI) model






8. Best known for LAN standards. Mission is to 'promote the engineering process of creating - developing - integrating - sharing - and applying knowledge about electro and information technologies and sciences for the benefit of humanity and the profess






9. Global hierarchy that maintains a database for worldwide frequency assignments and coordinates spectrum management through five administrative regions






10. The distance between similar points on two back-to-back waves. Typically measured from the peak of a wave to the peak of the next wave






11. Height - force - or power of a wave






12. The manipulation of a signal so that the receiving station has a way of distinguishing 0s and 1s






13. A term describing a behavior of waves. How fast the waves travel - or more specifically - how many waves are generated over a 1-second period of time






14. Independent United States agency that regulates communications to and from the United States. Regulates radio signals that are used for wireless networking






15. Range of all possible electromagnetic radiation






16. Method of manipulating a signal so that it can represent multiple pieces of data. It's what changes a signal into a carrier signal.






17. Non-profit group devoted to the growth of wireless LANs (WLANs). One of their primary task is to ensure interoperability of WLAN products by providing certification testing






18. The speed of an RF signal in a vaccum






19. The relationship between two waves with the same frequency






20. Wavelength=speed of light(constant)/Frequency.






21. Varies the height of a signal to represent binary data. A current state technique.






22. Effective area for receiving power (catching signals)






23. Varies the phase of the signal to represent the binary data. State transition technique. determines the data that is being transmitted. one phase can represent a 0 bit and another phase can represent a 1 bit






24. A current state technique. one frequency can represent a 0 bit and another frequency can represent a 1 bit
