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. Translated network addresses into their physical counterparts






2. A process that ensures one device does not send information faster than it can be received by another device.






3. A standard for encoding and interpreting binary files - images - video - and non-ASCII character sets within an e-mail message.






4. Device that modulates analog signals into digital signals for transmission over telephone lines - and demodulates digital signals into analog for the receiving end






5. Physical Layer






6. Provides th transfer medium (such as cable) - Translates data into a transmission signal appropriate to the transfer medium - Sends the signal along the transfer medium - Includes the pyical layout of the network - Monitors for transmission error - D






7. Firewall packet inspection that examines the data contained in a packet as well as the state of the connection between internal and external computers.






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






9. TFTP is a TCP/IP file transfer protocol that is designed for task such as the transfer of data to enable a diskless workstation to boot using files trasmitted from a server






10. 12 digits - A-F/0-9






11. Point or stage in a wave's progress over time






12. IKE






13. Transport Layer






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






15. An IP addressing convention that adheres to network class distinctions - in which the first 8 bits of a Class A address - the first 16 bits of a Class B address - and the first 24 bits of a Class C address are used for network Information






16. A medium that carries 1 signal






17. Used by web browser and web servers to exchange files






18. Address Resolution Protocol






19. A TCP/IP utility that queries the DNS database and provides information about a host given its IP address or vice versa. Dig is similar to the nslookup utility - but provides more information - even in its simplest form - than nslookup can.






20. MX






21. F type (like TV cable) or BNC (crimped)






22. Layer 1 Troubleshooting






23. NFS






24. Network device that makes high-level application connections on behalf of internal hosts and other machines






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






26. Multiplexing based on priority






27. A transmitter concentrates the signal energy at a single frequency or in a very small range of frequencies






28. Response generated atTransport layer confirming to sender that its frame was received; 3rd step in establishing a connection






29. BDC






30. Type of switching for multiple data packets make up the same transmission and use identical paths to reach the destination






31. A technique for transmitting data over a network by encapsulating it within another protocol.






32. Contains information that a wireless node needs to associate with an ap






33. The more resistant to cross talk (STP)






34. The capacity to send and receive signals at the same time on the same medium.






35. Point of division between a telecommunications service carrier's network and a building's internal network






36. Data terminal equipment - little independent data processing capability. ex. workstation






37. Data Link Layer






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






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






40. To make more efficient use of limited numbers of legitimate IP addressing






41. QoS






42. Device that separates a medium into multiple channels and issues signals to each of those subchannels






43. Which layer in the OSI is responsible for routing and controling the flow of packets around the network?






44. Layer 6






45. An Application layer protocol used to retrieve messages from a mail server. When a client retrieves mail via POP - messages previously stored on the mail server are downloaded to the client's workstation - and then deleted from the mail server.






46. The seventh layer of the OSI model. Application layer protocols enable software programs to negotiate formatting - procedural - security - synchronization - and other requirements with the network.






47. Amplitude modulation-amplitude of signal is modified






48. Transmission that involves one transmitter and multiple - undefined receivers






49. A network that links multiple LANs in a large city or metropolitan region.






50. Accurate alarm events that do not pose significant threat to information security
