A watchdog timer is a
computer hardware timing device that triggers a system
reset if the main
program, due to some fault condition, such as a
hang, neglects to regularly service the watchdog (writing a “service pulse” to it, also referred to as “petting the dog” or "kicking the watchdog"). The intention is to bring the system back from the hung state into normal operation.
