👉 Hibernacle is a term used in science and engineering to describe a process or event where a system goes into a low-power state, typically due to reduced energy consumption or maintenance. The term comes from the Greek word "hibernatio," which means "sleeping" or "rest." In this context, hibernacle refers to a state of rest and inactivity, often associated with animals such as bears, seals, and deer during winter months when they enter into hibernation cycles.
