Read the first 7 Computer Systems & Software Updates flashcards as text

  1. A marine technician needs to update the engine management system (EMS) software on a vessel's main propulsion unit. Which precaution is most critical?

    Answer: Ensuring the vessel is securely moored with engines stopped

    Engine management system updates must be performed with engines stopped and the vessel securely moored to prevent loss of propulsion control.

  2. In a shipboard local area network (LAN), what device is used to connect multiple computers and marine systems within the same network segment?

    Answer: Network switch

    A network switch connects multiple devices within the same LAN segment and directs traffic using MAC addresses.

  3. What is the function of an Uninterruptible Power Supply (UPS) connected to a vessel's navigation computer?

    Answer: To provide temporary battery power during power interruptions

    A UPS provides battery-backed power to keep critical navigation computers running during brief power outages, preventing data loss and system crashes.

  4. Which of the following best describes the NMEA 2000 standard compared to NMEA 0183?

    Answer: NMEA 2000 is a higher-bandwidth network that allows multiple devices on a single backbone

    NMEA 2000 is a CAN bus-based network standard that supports multiple devices communicating on a single backbone at much higher data rates than NMEA 0183.

  5. A vessel's integrated bridge system (IBS) displays an 'out of sync' warning after a software update to one subsystem. What does this typically indicate?

    Answer: Different subsystems are running incompatible software versions

    An 'out of sync' warning in an IBS usually means that one or more subsystems are running software versions that are not compatible with the others on the network.

  6. When a marine technician performs a factory reset on a chart plotter before installing updated software, what is the primary risk?

    Answer: Loss of all saved waypoints, routes, and user settings

    A factory reset erases all user-stored data including waypoints, routes, and custom settings, so these must be exported and backed up beforehand.

  7. What is the recommended method for transferring chart update files to an ECDIS unit that is not connected to the internet?

    Answer: Using an approved, virus-scanned USB drive or DVD

    Offline ECDIS units receive chart updates via approved removable media such as USB drives that have been scanned for malware before use.
