Cyber-physical systems

Definition

Cyber-physical systems (CPS) are integrations of computation, networking, and physical processes. They encompass a range of technologies that allow for real-time data exchange between digital systems and their physical counterparts, enabling monitoring, control, and automation of processes. This integration is crucial for enhancing system efficiency, safety, and reliability across various applications, particularly in automation and monitoring contexts.
