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. Four twisted wire pairs rated for 250 MHz.






2. A drawback of certification






3. Sequences packets in correct order






4. Equivalent to OSI Layer 2 Data Link & Layer 1 Physical






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






6. RADIUS






7. IEEE standard for broadband wireless in MAN (WiMAX)






8. Secure sockets layer-encyrpts TCP/IP transmission including web forms- en route b/w the client server using public key encryption technology






9. Resistance that contributes to controlling an electrical signal; measured in ohms






10. Application Layer






11. Twisted pair patch cable in which the termination locations of the transmit and receive wires on one end of the cable are reversed






12. A professional membership society that helps establish technical standards for the internet






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






14. Open source program that allows you too remotely take over another workstation and walk through support process






15. A generic term for data being transmitted






16. 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.






17. Transport Layer






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






19. Basic error checking and correction






20. Ethernet LAN-all forms of Ethernet media and interface






21. Max size of data units on Ethernet networks






22. HTTP/web/internet - change this port to make it more difficult for someone to connect to your web server






23. IMAP - internet message access protocol






24. A logical grouping of information that includes the network layer header and encapsulated data - but specifically does not include any headers and trailers below the network layer.






25. Receives a signal on one end - interprets it as 0 & 1 - then generates a new clean signal on the other end.






26. Does not operate at the application layer






27. Open Systems Interconnection model






28. 5 segments b/w two nodes - 4 repeating devices - and 3 segments connected by two repeating devices






29. Glass/plastic - light pulses high throughput - resistant to noise - most expensive cable






30. Firewall packet inspection that examines the data contained in a packet as well as the state of the connection between internal and external computers.






31. GSNW






32. Junction point between the MDF and concentrations of fewer connections; those that terminate in a telecommunications closet






33. The physical cables that link computers in a network






34. Form of transmission that allows multiple signals to travel simultaneously over one medium






35. The medium that carries multiple signals simultaneously






36. Name Of Layer 7






37. A service on a node






38. A station checks for existing wireless transmissions before starting the transmission






39. Physical Layer






40. This phase begins and end a PPP session.






41. Cross talk that occurs between wire pairs near the source of a signal






42. Facilities necessary for a service provider to connect with another organization LAN or WAN






43. Network-max segment length-100 meters






44. PPP






45. Restructuring data units that have been segmented






46. A connecting device for a network that accepts messages and passes them on to other parts of the network. Generally more intelligent than a hub.






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






48. A form of address translation that uses Tcp port numbers to distinguish each client's transmission - thus allowing multiple clients to share a limited number of Internet-recognized IP addresses.






49. IEEE standard describing specifications for wireless transmissions






50. Most common cabling used in networking. Usually connects nodes to the main network.
