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






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






3. 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






4. Shape and form of the AC signal






5. Height - force - or power of a wave






6. 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






7. In terms of CWNA it means the loss of signal strength.






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






9. 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






10. Effective area for receiving power (catching signals)






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






12. Developed Open Systems Interconnection (OSI) model






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






14. The speed of an RF signal in a vaccum






15. 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






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






17. Range of all possible electromagnetic radiation






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






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






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






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






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






23. The relationship between two waves with the same frequency






24. 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
