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. Used to resolve NetBIOS names w IP address






2. Total amount of communication cable that make up a network.






3. PRI






4. Two twisted wire pairs. It's the oldes type and is only voice grade - it isn't rated for data communication.






5. Transport Layer






6. A thin coaxial cable usually RG-58






7. Progress of a wave over a time in a relationship






8. IS designed for the exchange of electronic mail between networked systems -such as between mail servers over a TCP/IP network






9. Communications that occur in discrete units where the start of a unit is signaled by a start bit at the front and the end of the unit is signaled by a stop bit at the back.






10. A resistor that is connected to the end of a segment on a bus network - so that data-carrying signals are absorbed at the point where the segment stop. Aborbing the signals ensures they are not reflected back onto the cable after they reach the end-t






11. The Application layer TCP/IP subprotocol responsible for moving messages from one e-mail server to another.






12. Uses frame headers






13. Layer 7






14. IP






15. (fix) if analog shield twisted pairs or if digital with a repeater






16. Telnet






17. Requires many pulses to transmit same info that an analog can transmit in a wave






18. Connects multiple LANs






19. A term referring to a data-link header and trailer - plus the data encapsulated between the header and trailer.






20. Any end device on the network (for example: computers - printers - copy machines...)






21. The 100BaseVG/100VG-AnyLAN approach abandon the CSMA/CD transmission technique for one called demand priorTity.






22. Layer 1 Troubleshooting






23. Eight bits of information; in a digital signaling system - one byte carries one piece of information






24. Frequency modulation-frequency of signal is modified






25. Aka main cross-connect - first point of interconnection between an organization's LAN or WAN and a service provider's facility






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






27. Braided metal shielding used to insulate some types of coaxial cable






28. Cross talk that occurs between wire pairs near the source of a signal






29. Also called the physical or device address - the hexadecimal number permanently assigned to a network interface and used by the MAC sublayer within the DATA Link layer (Layer 2).






30. Wavelength division multiplexing






31. Communications for continuous burst of data controlled by a clock signal that starts each burst.






32. A type of transmission in which the entire channel capacity of the communications medium (such as cable) is used by one data signal - enabling only one node to transmit at a time.






33. Manages network communication - available on a CD-ROM for example - that is used to manage communications and how frames or packets are sent using a protocol.






34. Name Of Layer 7






35. Application Layer






36. Unix command at shell prompt to send a file to printer






37. Unit of data at any layer of the OSI model






38. Network Access Layer






39. Positive and zero. 1 and 0's.






40. Twist wire so you don't get interference on the memory






41. Anything - hardware or software - that monitors transmission of packets of digital information that attempt to pass the perimeter of a network






42. Private connection from a LAN to an internet service provider.






43. The means through which data is transmitted and received






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






45. Device used to regenerate a signal






46. A type of multimode fiber-optic cable that reflects the light-based signals like a mirror within the cable - resulting in different signals arriving at different times and with an increased likeihood of distortion over longer cable runs.






47. Simple Mail Transfer Protocol






48. Provides Internet access and/or other services such as email and Web hosting






49. Virtually local area network-device-switch






50. Which layer in the OSI network model handles data format information for networked communications?
