What Is A Cyber Physical System
A Cyber physical system is an integrated system that combines computational and physical elements to interact with and adapt to the real world. It merges the digital and physical zone, allowing the cyber (software, computing, communication) and the physical (sensors like radar, and cameras, actuators, and the real world) to work together effortlessly.
