IT: Networking Vocab

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. Technology that uses standard telephone wires and allows transmission of voice and data information. Slower than ADSL.






2. IP






3. Signals travel in one direction






4. Individual insulated wire pairs - less expensive then STP - less resistant to noise






5. Layer 5 through 7 Troubleshooting






6. Application Layer






7. Scrambles information into an alternative form that requires a key or password to decrypt the information.






8. A Data Link sublayer of the OSI model that initiates the communication link between nodes and ensures the link is not unintentionally broken.






9. 12-character string that uniquely identifies a network node - hard coded into the NIC by the manufacturer; composed ot the block ID and device ID






10. Which layer in the OSI is responsible for routing and controling the flow of packets around the network?






11. Guarantees that a server continually has power even if a buildings electrical service is interrupted - continuous voltage to a device by switching virtually instantaneously to the battery when it detects loss of power






12. Network configuration that allows selected outside organizations to access internal information systems.






13. AM






14. Receives a signal on one end - interprets it as 0 & 1 - then generates a new clean signal on the other end.






15. Backbone: A high-capacity communications medium that joins networks on the same floor in a building - on different floors - and across long distances.






16. Physical Layer






17. Teflon-coated cable that is used in plenum area because it does not emit a toxic vapor when burned






18. Used connecting a workstation to a routers console part






19. NLM






20. A wireless station listens on all channels for a bacon frame from an access point

22. Station transmits a probe that is then replied by the access point






23. Unwanted signals from sources near network cabling - such as motors and power lines






24. Is a secure form of HTTP






25. Form of transmission that allows multiple signals to travel simultaneously over one medium






26. Round time trip. time it takes for packet to get from sender to receiver and back






27. This layer in the OSI network model breaks up the files into packets to allow them to be sent around the network.






28. A network design consisting of a continuous path for data with no logical beginning or ending point - and thus no terminators.
