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. LC - ST - SC - or MT RJ






2. Lower sublayer of the Data Link layer; appends the physical address of the destination computer onto the fram






3. Device that separates broadcast domain






4. NTP






5. Supplying electrical power through ethernet






6. Set of routines that make up part of a software application

8. A very high speed - long distance media that consists of a single strand of fiber glass that carries the signals. Can transmit data 50 times further than multimode fiber at a faster rate






9. 3rd layer; protocols translate network addresses into their physical counterparts and decide how to route data from the sender to the receiver






10. A system of computers - printer devices - network devices - and computer software linked by communications cabling or radio waves.






11. Set of protocols that specify how wireless networks works. Most common are currently B and G. N is an emerging standard.






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






13. A computer that has its own CPU and may be used as a stand-alone computer for word processing - spreadsheet creation - or other software applications. It also may be used to access another computer such as another workstation or server via a network.






14. 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






15. UDP






16. Simple Mail Transfer Protocol






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






18. Describes the relative strength over a three dimensional area of an antenna






19. IEEE 802.2 Logical Link Control (LLC) sublayer of the data link layer






20. Process in which an NIDPS look for invalid data packets - packets that are malformed under the rules of the TCP/IP protocol






21. Multiple signals travel simultaneously - medium is separated into multiple channels






22. Internet assigned numbers authority






23. Internet Layer






24. PPP






25. IEEE standard for error and flow control in data frames






26. HDLC






27. Serial internet protocol






28. Small Form Plug-gables - Plugs in to an interface on a switch






29. Amplitude modulation-amplitude of signal is modified






30. Contains information that a wireless node needs to associate with an ap






31. DNS - Domain name system






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






33. Determines the network path on which to route packets - Help reduce network congestion - Establishes virtual circuits - Routes packets to other networks - resequencing packet transmissions when needed - Translates between protocols






34. Bus topology: A network design built by running cable from one PC or file server to the next - like links in a chain.






35. An International organization of scientists - engineers - technicians - and educators that play a leading role in developing standards for network cabling and data transmissions.






36. Layer 3 Troubleshooting






37. Minimum cabling standard for PoE






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






39. Which address is split in to four 8-bit parts called octets?






40. Network standard that can reliaby transmit data farthest






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






42. Short reach. only multimode-max length is 500. baseband transmission. 1000 mpbs.






43. A logical grouping of information that includes the network layer header and encapsulated data - but specifically does not include any headers and trailers below the network layer.






44. Twisted pair patch cable in which the termination locations of the transmit and receive wires on one end of the cable are reversed






45. Largest data unit a network will accept for transmission






46. Can use WPA to improve the security of data in transit






47. Layer 1






48. 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






49. The oldest type of network design - this topology consists of multiple nodes attached to a central hub - switch - or router.






50. A cable TV company - such as Comcast Broadband.
