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. A network transport control method used in Ethernet networks. It regulates transmission by sensing the presence of packet collisions.






2. Reflection in multiple different directions of a signal






3. Also called the star-wired ring topology - a network design in which the logic communication are in a ring - but the phyical layout of the network star.






4. A fixed number associated with a device's NIC






5. Each computer is connected to a central device






6. Serial internet protocol






7. A type of transmission that can vary continuously - as in a wave pattern with positive and negative voltage levels.






8. 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






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






10. 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.






11. Telecommunications industry association






12. Encrypts






13. In CIDR notation - the number of bits used for an extended network prefix. For example - the CIDR block for 199.34.89.0/22 is /22






14. A computer that accesses another computer - such as a workstation that accesses a shared file on another workstation - server - or mainframe. The client may use the accessed computer (host) to process data - or may process accessed data using its own






15. FDDI






16. The physical layout of a computer network






17. Uses multiple frequencies to transmit signal






18. A computer that has its own CPU and may be used as a stand-alone computer for word processing - spreadsheet creation - or other software applications. It also may be used to access another computer such as another workstation or server via a network.






19. Small network 192-223






20. RDP






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






22. 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






23. 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






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






25. Hardware that constitutes the enterprise-wide cabling system






26. Change in signal strength as a result of reflection - scattering - or diffraction






27. Allows for secure interactive control of remote systems






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






29. Process by which attacker changes the format and/or timing of their activities to avoid being detected by the IDPS






30. Provides th transfer medium (such as cable) - Translates data into a transmission signal appropriate to the transfer medium - Sends the signal along the transfer medium - Includes the pyical layout of the network - Monitors for transmission error - D






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






32. Routing protocol most likely used to replace a router for that handles traffic to and from the companies connection to its NSP






33. A unit of data formatted for transmission over a network that contains control and other information that corresponds to the OSI Networklayer; also called Layer 3.






34. An algorithm used to verify the accuracy of data contained in a data frame.






35. BRI






36. Also called the star-ring hybrid - topology - a network design in which the logic communication are in a ring - but the phyical layout of the network star.






37. Method of controlling how network nodes access communication channels - ex highway






38. A network design consisting of a continuous path for data with no logical beginning or ending point - and thus no terminators.






39. Presentation Layer






40. AD






41. Appends physical address of destination computer onto the frame






42. Device that can detect intrusion and launch an active response






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






44. Gigabit Interface Converter - Plugs in to an interface on a switch






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






46. An established guidline that specifies how networked data is formatted into packet or frame - how it is transmitted - and how it is interpreted at the receiving end.






47. Performs name resolution






48. LDAP






49. Layer 5 through 7 Troubleshooting






50. 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.
