システム

A system is a set of related parts that work together as a whole, and it can be classified based on how it exchanges energy or matter with its surroundings—isolated systems exchange nothing, closed systems exchange energy but not matter, and open systems exchange both. Understanding systems matters because this framework helps us analyze everything from chemical reactions to ecosystems to machines by clarifying what's included in our study and what can move in or out.
