Navy IT Communications Part 5 Practice Test

End-to-end communications on a Navy platform requires two segments: the internal network that generates and routes data, and the external medium that carries that data off the ship. The shipboard LAN handles creating, processing, and distributing information among onboard devices, ensuring the data is properly addressed and available where needed. The RF communications system provides the wireless link that actually transmits signals beyond the ship’s boundaries, enabling off-ship communication and connection to shore facilities or distant networks. Shore facilities are the far end of the link, not a segment inside the ship’s own path, so the two essential segments are the on-board LAN and the RF transmission system. Without the LAN, data cannot be produced or routed; without the RF link, the information cannot reach off-ship destinations.
