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.

7. PRI






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






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






10. PPP






11. Digital - one signal one channel at a time (half duplexing) ex. ethernet






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






13. SSH






14. A network on which any computer can communicate with other networked computers on an equal (peer) basic without going though an intermediary - such as a server. Peer-to-Peer networking enables each computer to offer and access shared resoures - such






15. (WIde area network) Carry networks longer distances than Lans






16. Unshielded twisted pair

20. Network news transfer protocol






21. Process of grouping almost identical alarms occurring at almost same time into single higher-level alarm






22. A computer on a network that requests services or resources from another computer on a network






23. Signals travel in both directions but only one at a time






24. Ppp tunneling protocol






25. Used to resolve NetBIOS names w IP address






26. OSPF






27. Reflection in multiple different directions of a signal

29. Network interface card






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






31. Value placed upon an IDPS's ability to detect/identify certain attacks correctly






32. String used to identify an access point - configure on your new access points to match the settings on existing access points






33. UDP






34. Medium network 128-191






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






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






37. Provides services for applications






38. Wrapping one layer's PDU with protocol information so that it can be interpreted by a lower layer






39. Four twisted wire pairs rated for 100 Mhz - but capable of handling the disturbance on eash pair that's caused by transmitting on all four pairs at the same time.






40. The ability to send or receive signals on a medium - but not at the same time.






41. 6th layer; protocols translate between Application and Network layers; data are formatted so that the network can understand - with the format varying according to the type of network; manages data encryption and decryption - such as scrambling of sy






42. Hardware device typically used to connect multiple LANs






43. Saturation of network bandwidth caused by excessive traffic - as when a large number of computers or devices attemp to transmit simultaneously - or when computers or devices presist in transmitting repeatedly.






44. SMF






45. 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






46. AMI






47. (local area network) network of computers and others that is confined to a relatively small space






48. The total amount of opposition to the flow of current.






49. AD
