Comptia Network + Wireless

Instructions:
  • Answer 29 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 process of mixing a data signal with a carrier wave






2. The ability of an antenna to transmit electromagnetic signals in all directions






3. A transmission technique that transmits data over different channels with in an assigned frequency range. Each channel is broadcast separately - or multiplexed.






4. Any standard not fully developed and adopted as an official standards recognized by IEEE






5. Refers to wireless network products used in the 802.11 category






6. Interference that matches the frequency of the carrier wave






7. A wireless network that contains one or more access points (WAPs)






8. A wireless networking device that provides a connection between a wireless network and a cable-based network and controls the data flow of all packets on the wireless network






9. Wireless network that does not contain a wireless access point (WAP)






10. An electromagnetic wave of a set frequency that is used to carry data






11. The ability of an antenna to focus or aim an electromagnetic signal in a particular direction






12. An electronic device that generates a carrier wave and modulates data signals into the carrier wave






13. A Bluetooth network






14. An orbit in which a satellite's rotational speed is synchronized with the aearth's rotational speed - making the satellite appear to stay in the same position relative to the Earth






15. The process of separating a data signal from a carrier wave






16. A technology based on radio waves connecting to designated areas referred to as cells






17. The time it takes data to be transmitted from the earth to a satellite






18. A transmission technique that uses multiple channels to transmit data either simultaneously or sequentially






19. Electromagnetic waves with a frequency range of 10 kHz to 3 -000 -000 MHz






20. A spread spectrum technique that transmits data on multiple channels sequentially






21. A data encryption protocol that makes a wireless network as secure as a wired network






22. The bandwidth of a carrier wave






23. The band of radio frequencies associated with industrial - scientific - and medical devices






24. A standard developed to insure the safe exchange of data between a wireless network and a portable Wi-Fi device such as a cell phone






25. An authentication protocol used on both wired and wireless systems






26. A protocol that combines the wireless authentication method with encryption






27. A spread spectrum technique that transmits data on multiple channels simultaneously






28. An unrestricted path for network transmissions






29. An electronic device that receives a modulated signal and demodulates it
