What are the definitions of the four categories of operational status?

The four categories of operational status typically include:

1. Operational: The system or facility is fully functional and performing its intended duties effectively.
2. Degraded: The system is operational but functioning at reduced capacity or efficiency, possibly due to minor issues.
3. Non-operational: The system is not currently functioning and cannot perform its intended duties, often requiring repairs or maintenance.
4. Standby: The system is not actively in use but is ready to be activated or deployed when needed.
