Safety-critical system

A safety-critical system is a kind of system that is designed to protect people from getting hurt. It can be a system inside a car, a plane, or a machine at a factory. The system is carefully designed so that it will help prevent accidents that might hurt people. For example, in a car, the safety-critical system is made up of seatbelts, airbags, and other electronic systems that help protect the driver and passengers if the car crashes.
