Introduction to Cyber-Physical System

Introduction to Cyber Physical System

A Cyber-Physical System (CPS) is a computing system that tightly integrates the physical world with computational elements. It combines hardware, software, networking, and physical processes to monitor, control, and interact with the physical world.

In a CPS, sensors and actuators are used to collect data from the physical environment (such as temperature, pressure, location, etc.), and this data is then processed and analyzed by embedded computing systems. Based on the analysis, the system can make decisions and take actions, often in real-time, to control or influence the physical processes.

CPS plays a crucial role in increasing interaction and communication through the use of computational intelligence. This helps us push the limits of what technology can do.
