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