Questions: According to systems theory, are the borders or margins that separate one entity from another. interfaces relationships roles boundaries

The answer is boundaries.

Interfaces refer to the points of interaction or communication between different systems or components within a system. While they are important in systems theory, they do not specifically denote the separation between entities.

Relationships describe the connections or interactions between entities within a system. They are crucial for understanding how systems function but do not define the separation between entities.

Roles refer to the functions or responsibilities assigned to different parts or members within a system. They help in organizing the system's operation but do not indicate separation.

Boundaries are the borders or margins that separate one entity from another in systems theory. They define the limits of a system and distinguish it from its environment or other systems. Boundaries are essential for understanding the scope and identity of a system.
