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. IEEE standard for Ethernet devices and data handling






2. Unit of data that results from subdividing a larger protocol data unit






3. A specially configured connection on a network device that is capable of viewing all the traffic that moves through the entire device.






4. PAP






5. VPN






6. AM






7. Open Systems Interconnection model






8. This phase begins and end a PPP session.






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






10. 3rd layer; protocols translate network addresses into their physical counterparts and decide how to route data from the sender to the receiver






11. File Transfere Protocol






12. Carrier sense multiple access with collision detection






13. POE standard






14. The scheme for assigning a unique identifying number to every node on a network






15. Decoy systems designed to lure potential attackers away from critical systems






16. Groups of workstations are star connect to connectivity devices and then networked via single bus - cover long distances - easy to interconnect - more expensive - ethernet






17. Transport layer protocol that services a request without requiring a verified session and without guaranteeing delivery data






18. IEEE standard for wireless networking






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






20. Frequency division multiplexing






21. Defines host IP in packet headers






22. A flexible communications cable that contains pairs of insulated copper wires that are twisted together for reduction of EMI and RFI and covered with an outer insulating jacket.






23. Decreasing the size of data units when moving data from a network that can handle larger units to one that can handle only smaller units






24. The wave bounces back when encountering an object






25. Networking technology developed by IBM in the 80s; relies upon direct links between nodes and ring topology - using tokens to allow nodes to transmit data






26. A versatile - chainable serial-bus technology that connects up to 127 devices at speeds of 1.5 Mbps and 12 Mbps as well as 480 Mbps.






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






28. Satellite used for broadband internet access






29. Used with single mode or multi mode fiber optic cable






30. Media Access Unit (transmitter/ receiver)






31. 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).






32. Communications that occur in discrete units where the start of a unit is signaled by a start bit at the front and the end of the unit is signaled by a stop bit at the back.






33. Internet assigned numbers authority






34. The process of connecting to a wireless network






35. Only two wire pairs are reversed






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






37. Allows you and eight coworkers to share a single internet routable IP address






38. The actual data - any communication that encodes a message






39. Package for data that includes not only the data - or 'payload -' but also the sender's and recipient's addressing and control information. Generated at the Data Link layer and issued to the Physical layer






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






41. A shell protocol that enables systems to use various authenticaion mechanisms.






42. A utility for viewing or modifying a host's routing table






43. A type of interference that occurs when two LAN cables run close to each other. If one cable is carrying a signal and the other isn't - the one carrying a signal will induce a 'ghost' signal in the other cable






44. More variable - convey greater subtleties with less energy






45. A common way of sharing resources on a peer-to-peer network






46. Modulation technique in which the amplitude of the carrier signal is modified by the application of a data signal






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






48. Two twisted wire pairs. It's the oldes type and is only voice grade - it isn't rated for data communication.






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






50. Standards organizations representing 157 countries headquartered in Geneva. Goal is to establish international standards to facilitate global exchange of information and barrier-free trade
