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.

21. Connects multiple LANs






22. Wall-mounted panel of data receptors into which cross-connect patch cables from the punch-down block are inserted






23. A network transport control method used in Ethernet networks. It regulates transmission by sensing the presence of packet collisions.






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






25. Pulses of precise - positive voltages and zero voltages (binary)






26. American national standards institute






27. A route discovery and analysis utility that comes with UNIX and Linux operating systems. Mtr combines with functions of the ping and traceroute commands and delivers an easily readable chart as its output






28. Wireless standard






29. On a cable-TV WAN - a central receiving point for signals from various sources - including satellite - major cable sources - and local tevevision sources.






30. A device that converts an analog to digital signal and vice versa






31. Standard that describes a security technique - wireless networks - in which a port is prevented from receiving traffic until the transmitters credentials are verified by authentication server






32. User datagram protocol






33. Coordinates and maintains communications between two nodes on the network






34. Interference that may be generated by broadcast signals from radio or TV towers






35. Device that separates broadcast domain






36. Single mode fiber






37. Is a challenge respone authentication protocol






38. Internet corporation for assigned names and numbers






39. Offers one way for a computer to access another computer over the network or over the Internet. For example - an IBM programmer can use Telnet on a Windows XP or Red Hat Enterprise Linux computer to access a mainframe though the Internet






40. Name Of Layer 7






41. The process of reconstructing segmented data






42. Device that enables networks or segments using different media to interconnect and exchange signals






43. A term used to refer to data within the Network layer of the OSI model.






44. Address Resolution Protocol






45. For fiber-optic cable communications - the difference between the transmitted power and the receiver sensitivity - as measured in decibels. It is the minimum transmitter power and receiver sensitivity needed for a signal to be sent and received fully






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






47. Assigning a unique frequency band to each communication






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






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






50. A Data Link sublayer that examines addressing information contained in a network frame and controls how devices share communications on the same network.
