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 ability of an antenna to transmit electromagnetic signals in all directions






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






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






4. 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






5. Interference that matches the frequency of the carrier wave






6. The bandwidth of a carrier wave






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






8. 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






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






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






11. A Bluetooth network






12. 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






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






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






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






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






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






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






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






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






21. An unrestricted path for network transmissions






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






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






24. The process of mixing a data signal with a carrier wave






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






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






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






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






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