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. SLIP






2. Can use WPA to improve the security of data in transit






3. Twist wire so you don't get interference on the memory






4. Packet one node sends to request a connection with another; 1st of three-step process of establishing a connection






5. AH






6. Allows an attached computer to act as a dumb terminal - with data processing taking place on the TCP/IP host computer






7. International society composed of engineering professionals - promotes development and education in the electrical engineering and computer fields






8. A type of fiber optic cable connector that uses a mechanism similar to the BNC connectors used by Thinnet






9. Determines the network path on which to route packets - Help reduce network congestion - Establishes virtual circuits - Routes packets to other networks - resequencing packet transmissions when needed - Translates between protocols






10. A network design consisting of a continuous path for data with no logical beginning or ending point - and thus no terminators.






11. IEEE 802.2 Logical Link Control (LLC) sublayer of the data link layer






12. Technology that uses standard telephone wires and allows transmission of voice and data information. Slower than ADSL.






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






14. Equivalent to OSI Layer 7 Application - Layer 6 Presentation - Layer 5 Session






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






16. The placement of data from a higher-layer protocol behind the header (and in some cases - between a header and trailer) of the next-lower-layer protocol. For example - an IP packet could be encapsulated in an Ethernet header and trailer before being






17. SNMP






18. A boundary between two zones of trust






19. Software that is stored on a chip in a device - such as in a ROM - and that typically composes some type of system software






20. Generates signals as changes in voltage at the NIC






21. PDC






22. Signals travel in one direction






23. HDLC






24. Manages end-to-end delivery of data






25. Signals travel in both directions but only one at a time






26. 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.






27. Data Link Layer






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






29. Consists of single cable that connects all nodes on a network without intervening connectivity devices - inexpensive - hard to find source of error - not very fault tolerant - data is transmitted in one direction in the ring.






30. Digital subscriber line- support multiple data and voice channels over a single line - extraordinary throughput though telephone lines






31. This layer in the OSI network model manages log on procedures and password recognition.






32. Is part of theTCP/IP protcol suite and used to retrive e-mail from a remote server to a local client over a TCP/IP connection






33. IPv6 addressing - multicast group






34. The physical layout of cable and wireless network devices and the logical path followed by network frames or packets sent on the cable or by wireless transmissions.






35. Enables sharing remote drivers - Enables sharing remote printers - Handles e-mail messages - Provides file transfer services - Provides file management services - Provides terminal emulation






36. Physical layer. 100 mpbs throughout. baseband transmission. cat 5 or higher utp. max length is 100 meters. two wire twisted pair-full duplexing.






37. Hard-to-define skills such as dependability






38. Works closely with IP in providing error and control information - by allowing hosts to exchange packet status information to help move the packets along the internetwork






39. 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






40. The action of luring an individual into committing a crime.






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






42. Occurs when attacker attempts to gain entry or disrupt normal operations of information systems - almost always with intent to do harm






43. Divides channel into different time slots and assigns data to nodes who are attached to time slots






44. Most resistant to EMI






45. A type of fiber optic connector. These connectors are square shaped and have release mechanisms to prevent the cable from accidentally being unplugged






46. International Organization for Standardization






47. Frequency Division Multiple Access






48. Process of retransmitting a digital signal; repeats the pure signal without the noise






49. Signals travel both directions simultaneously






50. Any device connected to a network - such as a microcomputer - mainframe - midrange computer - network equipment - or printer. Also called a station.
