What does the term "Sick" imply about a system's status?

The term "Sick" in reference to a system's status indicates that the system is degraded or partially operative. This condition suggests that while the system may still be functioning to some extent, it is not performing optimally and is likely experiencing issues that limit its effectiveness. This status usually alerts personnel to the need for monitoring and potentially addressing the underlying problems to restore full functionality.

In contrast, "fully operational" would imply that the system is working at its peak performance without any issues. "Requires immediate attention" indicates a more critical status than just being "sick," suggesting that the system might be non-functional or on the verge of complete failure. Lastly, "undergoing maintenance" refers to a planned downtime for repairs or upgrades, which fundamentally differs from a system that is simply impaired but still operational to an extent. Thus, the term "sick" is best captured by the definition of a system that is degraded or partially operative.
