25 Questions

1. Refers to whether the performance of a device - attached to a particular type of LAN - can be accurately predicted. Token Ring LANS are deterministic - but ethernet LANS are non deterministic.

2. An IPv4 address in the range of 169.254.1.0 to 169.254.254.255. Communication using these addresses is used with a ttl of 1 and limited to the local network

3. MDIX is an alternative operation of ethernet ports on a hub. In this mode - the mapping of the wire pairs used in the hub port is in a crossover configuration. This allows you to use a straight-through cable to interconnect the hub to another hub.

4. An international - nonprofit organization for the advancement of technology related to eletricity. IEEE maintains the standards defining many LAN protocols.

5. A corporate system such as a website that is explicitly used by internal employees. Can be assessed internally or remotely

6. Information systems that allow the creation of a document or documents that can be edited by more than one person in real time

7. An application protocol typically not used by end users. Instead - it is used by the network management software and networking devices to allow a network engineer to monitor and troubleshoot network problems.

8. The IPv4 address block 192.0.2.0 to 192.0.2.255 that is set aside for teaching and learning purposes. These addresses can be used in documentation and network examples.

9. The layer 3 address to which the data is going.

10. A part of a computer network that every device communicates with using the same physical medium. Network segments are extended by hubs or repeaters.

11. The arrangement of the nodes in a network and the physical connections between them. This is the representation of how the media is used to connect the devices.

12. Defines which wires in a cable should connect to each pin on the connectors on both ends of a cable. For example - a UTP cable used for ethernet - used for a straight-through cable pinout - connects the wire at pin 1 on one end with the pin 1 on the

13. One of the three basic binary logic operations. ANDing yields the following result: 1 and 1 = 1 - 1 and 0 = 0 - 0 and 1 = 0

14. A method of expressing a network prefix. It uses a forward slash / followed by the network prefix.

15. Another form of the root word converge in the phrase converged network. This kind of network aggregates various forms of traffic such as voice - video and data on the same network infrastructure. A more common usage represents the process by which ro

16. A model that consists of various layers that enable the development and explanation of technology to be done on a modular basis. This allows interoperability among different technologies among the different layers.

17. An IPV4 addressing scheme that uses a subnet mask that does not follow classful addressing limitations. It provides increased flexibility when dividing ranges of IP addresses into separate networks. Classless addressing is considered the best in curr

18. The glass fibers inside certain cables over which light is transmitted to encode 0 and 1

19. A protocol used between routers so that they can learn routes to add to their routing tables.

20. A special reserved IPv4 address - 127.0.0.1 that can be used to test TCP/IP applications. Packets sent to 127.0.0.1 by a computer never leave the computer or even require working NIC. Instead - the packet is processed by IP at the lowest layer and is

21. A network model defined by the IETF that has been implemented on most computers and network device in the world.

22. A 1-bit flag in the tcp header that indicates the acknowledgment field is valid.

23. The standards body responsible for the development and approval of TCP/IP standards

24. Application-level throughput. It is the number of useful bits per unit of time from a certain source address to a certain destination - excluding protocol overhead and excluding retransmitted data packets.

25. In ethernet - the process performed by a bridge or switch when it decides that it should not forward a frame out another port
