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






2. A protocol used to dynamically assign IP configurations to hosts. The services defined by the protocol are used to request and assign an IP address - default gateway - and DNS server address to a network host.






3. 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.






4. The connection of devices on a common media. Sometimes a physical network is also referred to as a network segment.






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






6. The largest IP packet size allowed to be sent out a particular interface. Ethernet interfaces default to an MTU of 1500 because the data field of an Ethernet frame should be limited to 1500 bytes - and the IP packet sits inside the ethernet frame's d






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






8. Somtimes called place-value notation - this is a numeral system in which each position is related to the next by a constant multiplier - a common ration - called the base or radix of that numeral system.






9. To transfer data from the computer functioning as a server to the client computer you are using.






10. 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






11. Define in RFC 1918 - an IP address that does not have to be globally unique because the address exists inside packets only when the packets are inside a single private IP internetwork. Private IP addresses are popularly used in most company today - w






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






13. A network with a geographic size between a LAN and a WAN. Typically used by service providers to create a highspeed network in a major metropolitan area where many customers might want high speed services between large sites around a city.






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






15. 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






16. A common term for 10base2 ethernet - referring to the fact that 10base2 cabling is thinner than coaxial cabling used for 10base5






17. 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.






18. The table used by a switch that associates MAC addresses with the outgoing port. A general term for the table that a LAN bridge uses for its forwarding/filtering decisions. The table holds a list of MAC addresses and the port out which the bridge sho






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






20. The time required to send a single bit over some transmission medium. The time can be calculated at 1/speed - where speed is the number of bits per second sent over the medium






21. A network topology characterized by a central location connected to multiple hubs. In an extended star - these interconnected hubs may be connected to more hubs. It is essentially a hierarchical topology but typically is drawn with the central site i






22. Can refer to computer hardware that is to be used by multiple concurrent users. Alternatively - this term can refer to computer software that provides services to many users. For example - a web server consists of web server software running on some






23. The spreading of light signal caused by light signals traveling at different speeds through a fiber.






24. Part of a company's intranet that is extended to users outside the company






25. 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






26. A series of documents and memoranda encompassing new research - innovations and methodologies applicable to Internet technologies. RFCs are a reference for how technologies should work.






27. The physical interface transceivers. It deals with Layer 1 (the physical layer - hence the PHY) of ethernet.






28. A communication path over a medium used to transport information from a sender to a receiver. Multiple channels can be multiplexed over a single cable






29. The optical or electrical impulse on a physical medium for purposes of communication.






30. 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.






31. 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.






32. The forwarding of packets where the forwarding decision is taken dynamically - hop by hop - based on the conditions of downstream fowrading nodes.






33. 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






34. 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






35. Also known as boolean algebra. These consist of the AND OR and IF operations






36. 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






37. A unicast IP address that is considered to have three parts: a network part - a subnet part - and a host part. The term classful refers to the fact that classful network rules are first applied to the address - and then the rest of the address can be
