  1. 2. The most common utility used to verify Layer 3 reachability.
  2. 5. The IP address of a router interface that a host uses to send traffic to remote networks.
  3. 7. The actual measure of the transfer of bits across the media over a given period.
  4. 9. The Media Access Control address, also known as the hardware or physical address.
  5. 11. The amount of time, including delays, for data to travel from one point to another.
  6. 12. A type of message sent to all hosts on a local network.
  7. 15. Unlike a physical topology, the logical topology focuses on how data flows and how IP addressing is structured.
  8. 17. These documents define the standards and protocols of the Internet.
  9. 19. A Wide Area Network, typically managed by a service provider (ISP).
  10. 20. The industry-standard protocol analyzer.
Down
  1. 1. The "wrapping" of data at each layer; the opposite process is de-encapsulation.
  2. 3. Sending a packet to a selected group of hosts.
  3. 4. A Layer 2 device that makes forwarding decisions based on MAC addresses.
  4. 6. An agreement on how communication is formatted, timed, and shared
  5. 8. Layer 1 of the OSI model, dealing with cables, connectors, and bit signals.
  6. 10. The contention-based media access method used by legacy Ethernet (abbreviation).
  7. 13. The primary intermediary device used to route traffic between different networks.
  8. 14. Layer 2 has frames, Layer 4 (Transport) uses segments.
  9. 16. Protocol used to map a known IPv4 address to a MAC address.
  10. 18. Fiber-optic cabling is immune to EMI and RFI because it uses light instead of electricity.
