sytem

A system is a set of interacting or interdependent components that form a complex and unified whole. Systems have boundaries, structures, and behaviors that enable them to achieve specific purposes or functions. They can be natural, such as ecological systems, or artificial, such as computer systems or organizational systems.

Systems are classified by domain: natural systems (ecosystems, the solar system, the nervous system); engineered or technical systems (computing systems, transportation networks, manufacturing systems); and social or organizational systems (economic systems, legal systems, institutions). Many systems are open, exchanging energy, matter, or information with their environment; others are relatively closed.

Common features include components and interfaces, feedback mechanisms, and emergent properties that arise from interactions among parts. Systems exhibit behavior at the system level that cannot be fully predicted from individual components alone. They are analyzed using systems thinking and modeling to understand flow, control, resilience, and adaptation.

The term "sytem" is typically a misspelling of "system," and may appear in errors or as a proper noun in rare cases. The word "system" derives from the Greek systema, through Latin systema, meaning a whole composed of parts.
