1. A connecting device for a network that accepts messages and passes them on to other parts of the network. Generally more intelligent than a hub.






2. A specialized UN agency that provides developing countries with technical expertise and equipment






3. Uses multiple frequencies to transmit signal






4. A shell protocol that enables systems to use various authenticaion mechanisms.






5. QoS






6. Most common cabling used in networking. Usually connects nodes to the main network.






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






8. International Organization for Standardization






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






10. A private computer network with resources accessible only to internal members.






11. Professional organization with 90 chapters around the world that helps to establish technical standards for the internet






12. A connector that is used for thin coax cable and that has a boyonet-like shell.






13. An authentication protocol that uses public key technology to provide users with secured access to network resources.






14. OTDR






15. A TCP/IP troubleshooting utility that provides information about NetBIOs names and their addresses. If you know the NetBIOs name of a workstation - you can use nbtstat to determine its IP address






16. A technique in which IP address used on a private network are assigned a public IP address by a gateway when accessing a public network.






17. What early protocol allows users to access machines remotley that has no security implemented within it?






18. Term that describes current anti-intrusion technologies






19. Large diameter. led/light is generated at different angles. high throughput - high noise resistance - excellent security - and long distances






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






21. Hard-to-define skills such as dependability






22. BERT






23. A route discovery and analysis utility that comes with UNIX and Linux operating systems. Mtr combines with functions of the ping and traceroute commands and delivers an easily readable chart as its output






24. Signals traveling on one wire infringes on the signal traveling over an adjacent wire






25. Device that separates broadcast domain






26. Services that handle hardware diagnoses and failure alerts






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






28. Session Layer






29. Transmission control Protocol/Internet protocol






30. A protocol that runs in the Dession and Transport layers of the OSI model and associates NetBIOS names with workstations. NetBIOS alone is not routable because it does not contain Network Layer information. However - when encapsulated in another prot






31. Tool used to determine whether a customers line is obtaining dial tone from the CO






32. Layer 5 through 7 Troubleshooting






33. IEEE standard for Ethernet devices and data handling






34. Defines the physical characteristics of the network






35. The wave bounces back when encountering an object






36. Institute of electrical and electronics engineers






37. A network that links multiple LAN's in large city or metropolitan region.






38. Using part of a leased line






39. A drawback of certification






40. PPPoE






41. Cross talk that occurs between wire pairs near the source of a signal






42. 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 stops. Absorbing the signals ensures they are not reflected back onto the cable after they reach the end






43. A logical process of combining bits. In ANDing - a bit with a value of 1 plus another bit with a value of 1 results in a 1. A bit with a value of 0 plus any other bit results in a 0.






44. Network interface card






45. Method of data modulation in which the frequency of the carrier signal is modified by the application of the data signal






46. An internetwork is two or more computer networks connected together.






47. Communications arrangement in which a single transmitter issues signals to multiple - defined recipients






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






49. RSA






50. Manages end-to-end delivery of data
