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. Degradation of a light signal on a fiber-optic network






2. DNS - Domain name system






3. Protocol data unit






4. Signals composed ot pulses that can have a value of only 1 or 0






5. Secure sockets layer-encyrpts TCP/IP transmission including web forms- en route b/w the client server using public key encryption technology






6. Station transmits a probe that is then replied by the access point






7. Activities finalize restoration of operations to a normal state and seek to identify source and method of intrusion to ensure same type of attack cannot occur again






8. EFS






9. Method of controlling how network nodes access communication channels - ex highway






10. NNTP






11. A remote connection where the client computer is a low-end computer that communicates with a terminal server.






12. IPX






13. Manages network communication - available on a CD-ROM for example - that is used to manage communications and how frames or packets are sent using a protocol.






14. Change in signal strength as a result of reflection - scattering - or diffraction






15. Physical Layer






16. On a network using the MIcrosoft Internet Connections Sharing service - the computer whose Internet connection other computers share. The ICS host must contain two network interfaces: one that connects to the Internet and one that connects to the LAN






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






18. Sequences packets in correct order






19. Amplitude modulation-amplitude of signal is modified






20. ICA






21. Provides strung security for HTTP- transpored information - but it is only used by some vendor's application






22. A system of computers - printer devices - network devices - and computer software linked by communications cabling or radio waves.






23. Which protocol allows users to send emails?






24. BDC






25. Is a secure form of HTTP






26. A generic term referring to the header defined by some layer of a networking model - and the data encapsulated by the header ( and possibly trailer) of that layer - but specifically not including an lower-layer headers and trailers.






27. Transport Layer






28. Techniques that employ hardware and software to province assurance against equipment failures - computer service interruptions - and data losses






29. Doesn't use frame headers - uses cells






30. More reliable then analog - noise doesn't affect as much - more efficient - fewer errors






31. Transport Layer






32. A transport system that uses the CSMA/CD access method for data transmission on a network. Typically it is implemented in a bus or star-bus hybrid topology.






33. The device inside a computer that connect a computer to the network media






34. A logical grouping of information that includes the network layer header and encapsulated data - but specifically does not include any headers and trailers below the network layer.






35. Services that handle hardware diagnoses and failure alerts






36. IKE






37. SMF






38. Used on many UNIX/LINUX systems to provide authentication security for TCP/IP applications such as Telnet and FTP






39. Protocol data unit. An OSI term to refer generically to a grouping of information by a particular layer of the OSI model. More specifically - an LxPDU would imply the data and headers as defined by Layer x.






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






41. FM






42. Performs name resolution






43. Connectivity device - data link layer (2) - reads header info to forward packets according to MAC addresses






44. A TCP/Ip troubleshooting utility that displays statistics and the state of current TCP/IP connections. It also displays ports - which can signal whether services are using the correct ports.






45. An organization composed of more than 100 representatives from industry and government who together determine standards for the electronics industry in addition to other fields - such as chemical and nuclear engineering.






46. Best fault tolerance






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






48. This layer in the OSI network model breaks up the files into packets to allow them to be sent around the network.






49. Faster networking and inexpensive - flexible - easy to install






50. Networking technology developed at Xerox in the 70s and improved by Digital Equipment Corp - Inel - and Xerox. Most common form of network transmission - follows IEEE 802.3 standard
