A system is a set of interacting or interrelated elements organized to form a unified whole that functions according to certain rules or principles. It is characterized by its structure, purpose, behavior, and interconnectivity of its parts, which work together toward a common goal or function

. Key aspects of a system include:

• Components : The parts or elements that make up the system.
• Interdependence : The components affect one another and the system as a whole.
• Boundaries : The limits that define what is inside the system and what is part of its environment.
• Purpose or function : The system performs a specific function or set of functions.
• Behavior : The overall behavior emerges from the interactions of the parts, not just from the parts individually

Systems can be physical (like the human respiratory system), abstract (like a classification system), simple (a recipe), complicated (a rocket), or complex (raising children)

. In summary, a system is an organized assembly of components that interact and depend on each other to achieve a particular purpose, and the whole system exhibits properties that cannot be understood solely by examining its parts separately
