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 network architecture designed to eliminate network downtime cause by a single point of failure.






2. 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.






3. As part of the TCP/IP internet layer - ICMP defines protocol messages used to inform network engineeres of how well an internetwork is working. For example - the ping command sends ICMP messages to determine whether a host can send packets ot another






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






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






6. A general type of cable - with the cable holding twisted pairs of copper wires and the cable itself having little shielding.






7. A physical or a logical area in a LAN where the signals sent by the interfaces ma be subject o being combined. Within a collision domain - if a device sends a frame on a network segment - every other device on that same segment will receive that fram






8. Program used to download and send email. Email clients use POP3 to receive emails and use SMTP to send emails. Also called an email client






9. An application level network protocl mainly applied to shared access to files - printers - serial ports - and miscellaneous communications between nodes on a network.






10. The process of obscuring information to make it unreadable without special knowledge - somtimes referred to as scrambling. The process takes the data to be encrypted and applies a mathematical formula to it along with a secret number. The resulting v






11. 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






12. A type of network cabling that includes twisted-pair wires - with shielding around each pair of wires - as well as another shield around all wires in the cable.






13. A computer program that runs in the background and is usually initiated as a process. Daemons often support server processes.






14. A process used to verify the identity of a person or process






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






16. A group of devices associated by the arrangement of a hierarchial addressing scheme. Devices in the same logical network that share a common network portion of their Layer 3 addresses.






17. A group that receives a multicast transmission. The members of a multicast group have the same mulitcast IP addressing to receive the same transmission.






18. A network device that accesses a service on another computer remotely by accessing the network.






19. Binary digit used in the binary numbering system. Binary digits are units of information storage and communication in computing. Each bit can be either a 0 or a 1.






20. A dotted decimal number defined by the IPv4 protocol to represent a network or subnet. It represents the network that hosts reside in. Also called a network number or network ID.






21. A rectangular cabling connector with eight pins - often used with ethernet cables.






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






23. As filed in the TCP header that is set in a sent segment - signifies the maximum amount of unacknowledged data the host is willing to receive before the other sending host must wait for an acknowledgment.






24. A protocol that allows a computer to retrieve email from a server.






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






26. In networking - a measurement of the speed of bits that can be transmitted over a particular link. It is the amount of data that can be transmitted in a certain amount of time. For digital bandwidth it is usually expressed in bits per second.






27. The ability of a protocol. system or component to be modified to fit a new need.






28. 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.






29. An international standards body that defines many networking standards. Also - the standards body that created the OSI model.






30. Resources used to manage or operate the network. Overhead consumes bandwidth and reduces the amount of application data that can be transported across the network.






31. The cabling and connectors used to interconnect the network devices.






32. The time that passes while some event occurs. In networking - latency typically refers to the time that occurs between when something is sent in a network until it is received by another device.






33. The minimum time a NIC or interface can take to send an entire frame. Slot time - then - implies a minimum frame size.






34. Used in the CLI following the command. Keywords are parameters that are used with the command from a set of predefined values.






35. 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






36. The normal operation of ethernet ports on a hub. In this mode - the mapping of the wire pairs in the hub port is in a normal configuration. Some hubs provide a media-dependent interface/media-dependent interface - crossover switch. This switch is usu






37. A numbering system characterized by 1 and 0






38. The process by which a router receives an incoming frame - discards the ata link header and trailer - makes a forwarding decision based on the destination IP address - adds a new data-link header and trailer based on the outgoing interface and forwar






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






40. A form of signal modulation where the message information is encoded in the amplitude of series of signal pulses. It transmits data by varying the aplitunes of the individual pulses. This is now obsolete and has been replaced by pulse code modulation






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






42. Communication that only allows one station to receive while the other station is transmitting






43. 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






44. In ethernet - the results of two nodes transmitting simlutaneously. The signals from each device are damaged when they combine on the media






45. The learning of source addresses on incoming frames and adding them to the bridging table. After the table has been completed and when a frame is received on one of the bridge's interfaces - the bridge looks up the frame's destination address in its






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






47. Radio frequencies that creat noise that interferes with information being transmitted across unshielded copper cabling.






48. Routing table entry that is used to direct frames for which a next hop is not explicitly listed in the routing table. This route is used to forward a packet when no other known route exists for a give packet's destination address.






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






50. In networking - a symbol used when drawing network diagrams that represent a part of the network whose details can be ignored for the purposes of the diagram.
