The correct answer is C) Wired local area network. Modern ships typically use a wired local area network (LAN) to connect multiple computers and systems aboard the vessel. This is because wired LANs provide a more reliable, secure, and high-speed data connection compared to wireless options, which can be susceptible to interference and connectivity issues in the maritime environment. Wired LANs also allow for better management, monitoring, and control of the various shipboard systems and functions. The other options are not as suitable for a typical ship's computer network. Wireless LANs and wide-area networks (WANs) can be used, but they are less common and may not provide the necessary performance and reliability required for critical shipboard operations. Wired WANs are generally used for long-distance communication, such as connecting the ship to shore-based facilities, rather than the on-board computer network.
