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. 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






2. A switching method that enables multiple devices to communicate over the same commnications medium by creating time slots in which each device transmits.






3. Network Layer






4. Domain Name System






5. Form of transmission in which signals are modulated as radiofrequency analog pulses with different frequency ranges; does not involve binary coding






6. A private network that functions like a tunnel through a larger network






7. Signals on bus that would travel endlessly between two nodes






8. A command-line utility that combines the functionality of the tracert and ping commands (similar to UNIX's mtr command) and comes with Windows XP - Vista - and Windows Server 2003 and Server 2008






9. Application Layer






10. Provides services for applications






11. Process of breaking large packets into smaller packets.






12. Is a challenge respone authentication protocol






13. Process in which an NIDPS inspects the higher-order protocols (HTTP - FTP - Telnet) are examined for unexpected packet behavior or improper use






14. Four twisted wire pairs rated for 100 Mhz.






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






16. Attacker who utilizes tactics designed to trip the organization's IDPS - essentially causing the organization to conduct its own DoS attack - but overreacting to an actual - but insignificant - attack.






17. Maximum arc into which you can loop a cable before you will cause data transmission errors






18. Uses multiple frequencies to transmit signal






19. 4th layer; protocols ensure that data are transferred from point A to point B reliably and without errors; services include flow control - acknowledgment - error correction - segmentation - reassembly - and sequencing






20. Cause by length - loss of signals as it travels farther away






21. Style of data transmission in which the pulses that represent bits follow one another along a single transmission line; sequentially issued






22. (WIde area network) Carry networks longer distances than Lans






23. Transport Layer






24. Local area network






25. RAS






26. Term that describes current anti-intrusion technologies






27. Data only






28. 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






29. Largest data unit a network will accept for transmission






30. Internet Layer






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






32. In TCP - a term used to describe a TCP header and its encapsulated data (also called an L4PDU). Also in TCP - the process of accepting a large chunk of data from the application layer and breaking it into smaller pieces that fit into TCP segments. In






33. Application Layer






34. The shorter the wavelength






35. An International organization of scientists - engineers - technicians - and educators that play a leading role in developing standards for network cabling and data transmissions.






36. 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.






37. The sender transmits the data to the destination without establishment of a connection.






38. Assigning a placeholder to each piece of a block of data to allow the receiving node's Transport layer to reassemble the data in the correct order






39. NLM






40. QoS






41. Layer 3 Troubleshooting






42. Ethernet NICs listen on network and wait until they detect no other nodes transmitting data






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






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






45. 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.






46. A type of cable used in network wiring and is usually shielded - which means that it is more immune to interference then unshielded cables






47. IEEE standard for Ethernet devices and data handling






48. Gives each node unique address






49. Data Link Layer






50. Network segment that contains end nodes - such as workstations
