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. Backbone: A high-capacity communications medium that joins networks on the same floor in a building - on different floors - and across long distances.






2. Name Of Layer 1






3. International society composed of engineering professionals with goals of promoting development and education in the electrical engineering and computer science fields






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






5. Layer 1






6. Virture privat network






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






8. CIFS






9. The physical layout of a computer network






10. Speed: 1000 Mbps - Altenative name: 1000BASE-T - IEEE Standard: IEEE 802.3ab - Cable type: copper max length 100m






11. Similar to FTP. lets you transfer files between a host and an FTP server






12. Every node on the network is connected through a central device like a switch - cannot be disabled by a single malfunction in a workstation - scalable - - popular - expensive - cable malfunction will only effect 2 workstations - more fault tolerant.






13. Basic error checking and correction






14. SSH - secure shell






15. Data circuit-terminating equipment. multiplexer or modem






16. First part of the datagram - which consists of general information about the size of the packet - the protocol that was used to send it - and the IP address of both the source computer and its destination.






17. Wrapping one layer's PDU with protocol information so that it can be interpreted by a lower layer






18. Data transmission that involves one transmitter and one receiver






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






20. IEEE standard for token ring devices and data handling






21. 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






22. Type of interference that may be caused by motors - power lines - televisions - copiers - etc






23. Transport Layer






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






25. Dynamic Host Configuration Protocol






26. Unshielded twisted pair






27. Type of multiplexing that assigns a unique frequncy band to each communications subchannel






28. Coordinates and maintains communications between two nodes on the network






29. Provides service that ensure accurate and timely delivery of network communications between two hosts






30. Layer 1 Troubleshooting






31. Distance between corresponding points on cycle






32. A high-capacity communications medium that joins networks on the same floor in a building - on different floors - and across long distances.






33. The IEEE stanard for error and flow control in data frames.






34. Open Systems Interconnection model is standard description or reference model for how messages should be transmitted between any 2 points in a telecommunications network.






35. 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






36. Useful for troubleshooting a network connectivity problem from workstation to another workstation






37. A Data Link sublayer of the OSI model that initiates the communication link between nodes and ensures the link is not unintentionally broken.






38. End-user device - such as a workstation - terminal - or console






39. NNTP






40. Regular voice-grade telephone service.






41. Capability for a component or system to continue functioning despite damage or malfunction






42. A term used to refer to data within the Network layer of the OSI model.






43. Loop back address for IPv6






44. Appends physical address of destination computer onto the frame






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






46. Individual insulated wire pairs - less expensive then STP - less resistant to noise






47. Is a host-to-host protocol like TCP - however it does not include mechanisms for ensuring timely delivery






48. A TCP/IP utility that at its simplest returns either to IP address of a host if its host name is specified or its host name if its IP address is specified






49. Addresses packet size






50. Internet Engineering Task Force
