Question 92Electricity & Electronics - 1st Asst/Chief

The correct answer is A) Wired local area network. Modern ships typically use a wired local area network (LAN) to connect the various computer systems and devices aboard the vessel. This allows for reliable and secure communication between the different shipboard functions, such as navigation, engine control, and communications. A wired LAN provides a robust and hardwired infrastructure that is well-suited for the marine environment and meets the regulatory requirements for maritime data networks. The other options are not as appropriate for most ships. Wireless LANs (B) can be used but may not provide the same level of reliability and security as a wired network. Wireless wide area networks (C) are typically used for long-distance communication, not for the local network aboard a ship. Wired wide area networks (D) are not commonly used for the internal shipboard systems, as they are designed for connecting remote locations, not for the local network on a vessel.
