# Client-Server Relationship

A fundamental principle (Axiom II) stating that every networked software system is based on client-server or caller-called function interaction at various levels. The relationship is contextual: the entity requesting a service is the "client," and the entity providing that service is the "server". Roles can be dynamic and change depending on interaction context, particularly across protection ring boundaries.
