Cyber-physical systems

Definition

Cyber-physical systems are integrations of computation, networking, and physical processes that enable intelligent interaction between the digital and physical worlds. These systems rely on sensors, actuators, and software to monitor and control physical environments, enhancing decision-making and operational efficiency. Their design and functionality are closely tied to the Internet of Things (IoT), as they leverage sensor networks to collect data and facilitate real-time responses to changes in their surroundings.
