Final answer:
The error message 'Non-recoverable fault, system restart required' means that the system encountered a fault that cannot be fixed and requires a restart.
Step-by-step explanation:
The meaning of the error message 'Non-recoverable fault, system restart required' is 1) The system encountered a fault that cannot be fixed and requires a restart. "Non-recoverable fault, system restart required" implies that the system has encountered a critical fault or error that cannot be resolved without a complete restart. Option 1) "The system encountered a fault that cannot be fixed and requires a restart" is the correct interpretation. In this scenario, the fault is severe and has caused the system to reach a state where continuing normal operations is not possible without a reboot. Restarting the system is necessary to clear the error state, reset the system components, and potentially load a clean and stable state to resume normal functioning.
