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. Network layer device






2. Application Layer






3. Honey pot that has been protected so it cannot be easily compromised






4. Open Systems Interconnection model is standard description or reference model for how messages should be transmitted between any 2 points in a telecommunications network.






5. 2nd layer; bridges the networking media with the Network layer. Primary function is to divide the data it receives from the Network layer into frames to be transmitted by the Physical layer






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






7. Allows you and eight coworkers to share a single internet routable IP address






8. NTP






9. TFTP is a TCP/IP file transfer protocol that is designed for task such as the transfer of data to enable a diskless workstation to boot using files trasmitted from a server






10. Device that separates broadcast domain






11. International Organization for Standardization






12. IPv6 addressing - multicast group






13. Ensures that messages being transmitted on the internet are private and tamper proof






14. NLM






15. Groups of workstations are star connect to connectivity devices and then networked via single bus - cover long distances - easy to interconnect - more expensive - ethernet






16. Style of data transmission in which the pulses that represent bits follow one another along a single transmission line; sequentially issued






17. A type of address translation in which each private IP address is correlated with its own Internet-recognized IP address.






18. Extended service set: a group of access points






19. SSH - secure shell






20. Gigabit Interface Converter - Plugs in to an interface on a switch






21. Data transmission that involves one transmitter and one receiver






22. Protocol data unit






23. OTDR






24. A group of two or more computer systems linked together.






25. The seventh layer of the OSI model. Application layer protocols enable software programs to negotiate formatting - procedural - security - synchronization - and other requirements with the network.






26. Device that acts as a wireless switch so that nodes can connect wirelessly to a network.






27. Minimum cabling standard for PoE






28. Provides FTP - HTTP - SMTP...






29. Term that describes current anti-intrusion technologies






30. 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.






31. A coaxial connector uses a twist and lock style - may be used with Rg-6 and RG-59






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






33. On a computer that receives data over a network - the process in which the device interprets the lower-layer headers and - when finished with each header - removes the header - revealing the next-higher-layer PDU.






34. (fix) if analog an amplifier or if digital with repeater






35. Firewalls perform two basic security functions






36. Representatives from electronics manufacturers across the US that sets standards for electronic equipment and lobbies for legislation favorable to the growth of the computer and electronics industries
