IT: Networking Vocab

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. Secure Sockets Layer






2. SLIP






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






4. Facilities necessary for a service provider to connect with another organization LAN or WAN






5. A frame (or packet) sent to all nodes on the network.






6. ICS






7. Area above the ceiling tile or below the subfloor in a building






8. Model for understanding and developing computer-to-computer communication developed in the 80s by ISO; divides networking functions among 7 layers






9. Decreasing the size of data units when moving data from a network that can handle larger units to one that can handle only smaller units






10. Physical layer standard for serial communications






11. Private connection from a LAN to an internet service provider.






12. Type of sensor deployed in such a way that the network traffic it is monitoring must pass through it.






13. Network Layer






14. A transmission method that has distinct signal levels to represent binary zeroes or ones - such as +5 volts and 0 volts.






15. A worldwide network of interconnected LANs and MANs that uses the TCP/IP protocol to enable people to shares e-mail messages and computer files and to access a vast array of information.






16. An IP addressing and subnetting method in which network and host information is manipulated without adhering to the limitations imposed by traditional network class distinctions. CIDR is also known as classless routing or supernetting. Older routing






17. Is used to allow searching and updating of a directory service






18. Hardware device typically used to connect multiple LANs






19. 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.






20. Uses frame headers






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






22. Logical link control






23. Data Link Layer






24. Also called the star-wired bus topology - a network design that combines the logial comunications of a bus with the physical layout of a star.






25. Process in which an NIDPS look for invalid data packets - packets that are malformed under the rules of the TCP/IP protocol






26. Requires many pulses to transmit same info that an analog can transmit in a wave






27. A computer that accesses another computer - such as a workstation that accesses a shared file on another workstation - server - or mainframe. The client may use the accessed computer (host) to process data - or may process accessed data using its own






28. 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






29. LLC






30. A type of interference that occurs when two LAN cables run close to each other. If one cable is carrying a signal and the other isn't - the one carrying a signal will induce a 'ghost' signal in the other cable






31. 192-223






32. Translates data to a format the receiving node understands - such as from EBCDIC to ASCII - Performs data encryption - Performs data compression






33. 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.






34. Routes packets through network






35. Electromagnetic interference. waves from electrical devices. ex. RFI






36. Standard analog telephone system






37. Radio frequency interference. interference caused by radio.






38. Anything - hardware or software - that monitors transmission of packets of digital information that attempt to pass the perimeter of a network






39. A unit of data transmitted on a network that contains control and address information corresponding to the OSI Data Link layer - or Layer 2.






40. A data encryption technique employed between a server and a client - such as between a client's browser and an Internet server.






41. Transport protocol and TCP/IP port that uses telnet utility use






42. Unlicensed band with 11 channels






43. CRAM-MD5






44. A fiber-optic data transport method capable of a 100-Mbps transfer rate using a dual ring topology; largely supplanted today by faster Ethernet method.






45. Transport Layer






46. PPP






47. Is a host-to-host protocol like TCP - however it does not include mechanisms for ensuring timely delivery






48. (fix) if analog shield twisted pairs or if digital with a repeater






49. Data circuit-terminating equipment. multiplexer or modem






50. Measure of a signal's strength
