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. GBIC






2. Two communication systems establish 2-way communication prior to the exchange of data






3. A generic term referring to any set of protocols and standards collected into a comprehensive grouping that - when followed by the devices in a network - allows all the devices to communicate. Examples include TCP/IP and OSI.






4. Describes the relative strength over a three dimensional area of an antenna






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






6. Packet internet groper






7. Vulnerability created in a system by a virus or worm which allows the attacker to access the system at will with special privileges.






8. IP






9. Speed: 1000 Mbps - Alternative name: 1000BASE-LX - 1000BASE-SX - IEEE Standard: IEEE 802.3z - Cable Type: Fiber max length 550m (sx) - 5 km(lx)






10. User friendly web addresses are translated into IP addresses by the...






11. Manually specify on each workstation so that their users can pick up their internet email from the linux email server






12. Where demarc is located if an organization follows structured cabling standards






13. QoS technique enables packet switches technologies to travel over traditionally circuit switched connections






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






15. Is a secure form of HTTP






16. POE standard






17. Theoretical. difference b/w highest and lowest frequency.






18. A series of interconnected computers - printing devices - and other computer equipment that share hardware and software resources. The services area usually is limited to a given office - floor - or building.






19. FM






20. The distinct units of data that are exchanged between nodes on a network






21. A service used via the Application layer to recognize and access other layers






22. Also called the physical or MAC address - the hexadecimal number permanently assigned to a network interface and used by the MAC sublayer within the DATA Link layer (Layer 2).






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






24. Attachment Unit Interface Cable equipped with 15 pin connectors






25. Data Link Layer






26. Guarantees that a server continually has power even if a buildings electrical service is interrupted - continuous voltage to a device by switching virtually instantaneously to the battery when it detects loss of power






27. An app. that provides centralized authentication and authorization services for a network.






28. A resistor that is connected to the end of a segment on a bus network - so that data-carrying signals are absorbed at the point where the segment stops. Absorbing the signals ensures they are not reflected back onto the cable after they reach the end






29. Uses multiple frequencies to transmit signal






30. More variable - convey greater subtleties with less energy






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






32. On a computer that receives data over a network - the process in which the device interprets the lower-layer headers and - when finished with each header - removes the header - revealing the next-higher-layer PDU.






33. Is a protocol for defining host groups.






34. Application Layer






35. Transport Layer






36. A Data Link sublayer that examines addressing information contained in a network frame and controls how devices share communications on the same network.






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






38. ISM






39. Physical layer. 10 mpbs throughput. baseband transmission. max length is 100 meters. follows 5-4-3 rule. star topology. cat 3 or higher utp. twisted pair.






40. Prevents broadcast storms by enabling switches to calculate paths that avoid potential loops and artificially block the links that would complete a loop






41. Telnet






42. Layer 4 Troubleshooting






43. Direct-sequence spread spectrum: signal bits are distributed over a frequency band






44. Four twisted wire pairs rated for 100 Mhz.






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






46. A device that converts an analog to digital signal and vice versa






47. A single physical/non-physical medium for connecting computers






48. Service that supports email






49. Also called coax - a network cable medium that consists of a copper core - surrounded by insulation.






50. HTTPS - Secure implementation of HTTP
