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. A device that converts an analog to digital signal and vice versa






2. 192-223






3. 128-191






4. Tools in order to connect a new RJ45






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






6. Device that connects network segments and directs data based on information in the data packet






7. The cabling or radio waves used to connect one network computer to another - or one network to another - and transport data between them. - Means by which a communications signal is carried from one system to another (for example - twisted-pair wire






8. Also called coax - a network cable medium that consists of a copper core - surrounded by insulation.






9. SNMP






10. Multimode fiber






11. Brief delay in processing - length of cable can contribute to this






12. Translated network addresses into their physical counterparts






13. Twisted pair cable consisting of a number of twisted pairs of copper wire with a simple plastic casing. Because - no shielding is used in this cable - it is very susceptible to EMI - RFI - and other types of interference






14. Metropolitan area network






15. Round time trip. time it takes for packet to get from sender to receiver and back






16. Multiple physical/non-physical mediums for connecting computers






17. Strategy that combines the best of the other two strategies; while individual agents still analyze and respond to local threats - their reporting to a hierarchical central facility enables the organization to detect widespread attacks






18. Tracks running and graphing data from any workstations. should ensure that new routers and switches can support it in order to easily automate network management






19. Most resistant to EMI






20. Cabling that transmit data using light waves. Higher bandwidth than other types of cabling.






21. Event that triggers alarm when no actual attack is in progress






22. LC - ST - SC - or MT RJ






23. Encrypts






24. The cableing or radio waves used to connect one network computer to another - or one network to another - and transport data between them.






25. Coordinates and maintains communications between two nodes on the network






26. Layer 2 Troubleshooting






27. FDM






28. A specialized device that allows multiple networks or segments to connect and exchange data






29. Technique for formatting signals in which one property of a carrier wave is modified by the addition of a data signal during transmission






30. 185 meters - 10Mbps






31. A versatile - chainable serial-bus technology that connects up to 127 devices at speeds of 1.5 Mbps and 12 Mbps as well as 480 Mbps.






32. PDC






33. Prevents broadcast storms by enabling switches to calculate paths that avoid potential loops and artificially block the links that would complete a loop






34. L2TP






35. Basic service set: a group of stations that share an access point






36. 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






37. ISM






38. Equivalent to OSI Layer 4 Transport






39. Similar to bus topology - but the ends are connected






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






41. Ppp tunneling protocol






42. Connection based






43. Largest data unit a network will accept for transmission






44. What is an agreed set of rules that two parties agree on in order to communicate with each other commanly known as?






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






46. A switchhing method that creates separte channels on one communication medium by establishing different frequencies for each channel.






47. Defines the physical characteristics of the network






48. A network that any user can access with no restrictions. the most familiar example of a public network is the Internet






49. Interference that may be generated by broadcast signals from radio or TV towers






50. 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.
