CCNA Network Fundamentals Vocab

Subjects : cisco, it-skills, ccna
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 time period between ethernet frames that allows fairness with the CSMA/CD algorithm. Without a space between frames in other words - without some time with no frames being sent a NIC might always listen for silence - never hear silence and therefor






2. Used by tcp or udp - with values between 0 and 1023 - these ports are allocated by high-privilege processes. They are used so that all clients know the correct port number to connect to.






3. A collection of data that establishes a reference for network performance and behavior over a period of time. This reference data is used in the future to assess the health and relative growth of network utilization.






4. A device on a network that serves as an access point to other networks. A default gateway is used by a host to forward IP packets that have destination addresses outside the local subnet. A router interface typically is used as the default gateway. W






5. The lower of the two sublayers of the IEEE standard for ethernet. It is also the name of that sublayer






6. A 32-bit number - written in dotted decimal notation - used by the IP to uniquely identify an interface connected to an IP network. It is also used as a destination address in an IP header to allow routing - and as a source address to allow a compute






7. A system of network design characterized by one or more major components that are required to maintain operation.






8. The design on networks that can continue to operate without interruption in the case of hardware - software or communications failures.






9. A network device that has an IPv4 address assigned to it to communication over a network.






10. A numbering system characterized by 1 and 0






11. The loss of communication signal on the media. This loss is due to degradation of the energy wave over time.






12. A related set of communications transactions between two or more network devices.






13. Additional data that is provided with a command to provide information used by the execution of the command. IOS command arguments are entered at the CLI after the command






14. The method of for finding a host's hardware address from its IPv4 network layer address.






15. A 1-bit flag in the TCP header used to indicate that the receiving host should notify the destination process to do urgent processing.






16. A process that uses the same ARP messages as a normal ARP - but by which a router replies instead of the host listed in the ARP request. When a router sees an ARP request that cannot reach the intended host - but for which the router knows a route to






17. A request for information. Queries are answered with replies.






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






19. When used generically - this term refers to end-user data along with networking headers and trailers that are transmitted through a network. When used specifically - it is end-user data - along with the network or Internet layer headers and any highe






20. A data link layer address - for example a MAC address






21. In a web browser - an application the browser uses - inside the browser window to display some types of content. For example - a browser typically uses a plug-in to display video.






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






23. Line code in which 1s are represented by one significant condition and 0s are represented by another.






24. IPv4 address of a network host. When talking about host addresses - they are the network layer addresses.






25. A form of transmission where one device transmits to all devices within the network or on another network






26. 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.






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






28. 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






29. Communication where the sender and receiver must prearrange for communications to occur; otherwise - the communication fails.






30. A method of internal processing by LAN switches. The switch must receive the entire frame before it sends the first bit of the frame. Store and forward switch is the method used by cisco switches.






31. A number used in the 802.11 header to specify the session between a wireless client and the access point.






32. A map of the devices on a network representing how the devices communcate with each other.






33. In ethernet - the process performed by a bridge or switch when it decides that it should send a frame out another port.






34. Network protocols or technologies that do not use the acknowledgment system to guarantee reliable delivery of information






35. Interface by magnetic signals caused by the flow of electricity. EMI can cause reduced data integrity and increased error rates on transmission channels. The physics of this process are that electrical current creates magnetic fields - which in turn






36. A host or node that participates in some form of a group. For example - p2p technology defines a group of peers that participate jointly in the same activity - each one having a server and client component.






37. A written specification that defines what tasks a service or device should perform. Each protocol defines messages - often in the form of headers - plus the rules and processes by which these messages are used to achieve some stated purpose.






38. An internationally recognized definition of technical specifications that ensure worldwide consistency.






39. An organization that assigns the numbers important to the proper operation of the TCP/IP protocol and the Internet - including assigning globally unique IP addresses.






40. The range of ip addresses that can be assigned by the DHCP server.






41. A routing feature in which frames in an interface output queue are prioritized based on various characteristics such as packet size and interface type.






42. A high-speed line or series of connections that forms a major pathway within a network. The term is often used to describe the main network connections comprising the Internet.






43. The origin of the PDU. This can be a process a host or a node - depending on the layer to which you are reffering.






44. Ethernet that transmits data at 1 -000 -000 -000 one billion bits per second.






45. A grouping of code that meets a certain - already specified - condition for entering in that certain group.






46. A delineation of networking protocols and standards into different categories - called layers - along with definitions of which sets of standards and protocols need to be implemented to create products that can be used to create a working network






47. Data that directs a process. a flag in a data-link frame is an example of control data.






48. Data link layer term describing a device connected to a network.






49. Devices at the user end of a user-network interface that serves as a data source - destination or both. DTE connects to a data network through a DCE device and typically uses clocking signals generated by the DCE. DTE includes such devices as compute






50. A member of a multicast group. Every multicast client in each group has the same IP address. Multicast addresses begin with 224... and end with 239...
