What is a simple definition of a system?

A system is best defined as a whole consisting of interacting parts. This definition captures the essential nature of a system, which is that it is made up of multiple components that work together to achieve a common purpose or function. Each part within a system influences and is influenced by the other parts, creating a dynamic interaction that is critical to the system's overall behavior and performance.

This concept highlights the importance of relationships and interactions in understanding how a system operates, as simply having parts in isolation would not qualify as a system. Therefore, defining a system this way underscores the interconnectedness and interdependence of its components, celebrating the complexity and functionality that emerges when they come together to form a cohesive whole.
