Also to note "watchdog" the term. Is used also in hardware/software context. Usually as a way to mitgate or recover system faulate. I first I heard of this term while taking in a course about PIC microcontroller[1].

> The Watchdog Timer in the PIC16F819 The watchdog timer can be a real source of pain and can also make a PIC system incredibly robust and reliable. But what exactly is the watchdog timer? Simply put, the watchdog timer is a hardware timer in the PIC that, if not constantly reset by the software, will cause the PIC to reset. This feature can be incredibly useful if the PIC should hang due to a hardware or software issue and guarantees that the PIC will restart from the beginning. Not only does it reset the system, it also flags a bit that can be used to determine if the system just crashed.
