What are the three segments of End-to-End communications?

• A. Shipboard LAN, RF communications systems, Shore facilities
• B. Shipboard LANs, RF communications systems, Shore facilities
• C. Shipboard LAN, RF communications, Shore facilities
• D. Shipboard LAN, RF communications systems, Shore facility

Answer: (A)

The three segments of End-to-End communications are the shipboard LAN, the RF communications systems, and the shore facilities. The shipboard LAN handles all internal on-board data traffic and user access. The RF communications systems provide the over-the-air link that carries data between the ship and shore, including radios, antennas, and modems. The shore facilities are the onshore network infrastructure that terminates the link and connects to the wider network and services. This combination creates a complete path from an on-board device to off-shore destinations. Variations like labeling the ship network as LANs or dropping words such as “systems” or “facility” blur the distinct segments and aren’t as precise.
