What does the value "Online" indicate when using the display device command?

The value "Online" in the context of the display device command indicates that the board is operational and fully connected to the system. This status signifies that the hardware components are functioning as expected and are ready to perform tasks, making them available for processing data or handling requests.

When a board is marked as "Present" and indicates that it is "Online," it confirms not only that the hardware exists and is recognized by the system but also that it is actively engaged in its intended operations. This is essential for system performance and reliability, as online components can provide the necessary services without interruption.

In contrast, other statuses such as "Absent" or "Unavailable" reflect conditions where the hardware may not be functioning correctly or is not connected, but "Online" is definitive in asserting that the device is operational and ready for use.
