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.

15. Authentication prtocol that does not issue a challenge or require 3rd party verification of the computer requestiing authentication






16. All wires are reversed






17. Control frame that indicates to the rest of the network that a particular node has the right to transmit data






18. Type of transmission in which signlas may travel in both directions over a medium - but only in one direction at a time






19. A standard for encoding and interpreting binary files - images - video - and non-ASCII character sets within an e-mail message.






20. Transport Layer






21. Strength of digital signal






22. NTP - network time protocol






23. Security measure verifies that your user name and password are contained in the NOS directory






24. An adapter board designed to connect a workstation - server - or other network device to a network medium.






25. Determines standards for the electronics industry and other fields - such as chemical and nuclear engineering - health and safety - and construction






26. Minimum cabling standard for PoE






27. Which protocol provides the user with many functions of the world wide web?






28. The _____________ allows computers to 'talk' to themselves on a different port.






29. A generic term referring to any set of protocols and standards collected into a comprehensive grouping that - when followed by the devices in a network - allows all the devices to communicate. Examples include TCP/IP and OSI.






30. Application Layer






31. Central component of a cable designed to carry a signal






32. An established guidline that specifies how networked data is formatted into packet or frame - how it is transmitted - and how it is interpreted at the receiving end.






33. Panel of data receptors into which twisted pair wire is inserted to complete a circuit






34. Transport Layer






35. Communications cable that consists of one or more glass 0r plastic fiber cores inside a protective cladding material - covered by a plastic PVC outer jacket. Signal transmission along the inside fibers typically uses infrared light.

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






40. Unique identifying number for a network node; follows a hierarchical addressing scheme; can be assigned through OS software; added to data packets and interpreted by protocols at the Network layer






41. Frequency hoping spread spectrum: a signal jumps between several different frequencies






42. A connector used to terminate coaxial cable used for transmitting television and broadband cable signals






43. International Organization for Standardization






44. OTDR






45. Layer 3 Troubleshooting






46. Four twisted wire pairs with three twists per foot. This type can handle transmissions up to 16 MHz. Now limited to telecommunication equipment






47. A cable that consists of a single cable sheath containing a combination of fibers and copper cable.






48. Controls how applications access network






49. A connecting device for a network that accepts messages and broadcasts them out to the rest of the network.






50. 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.
