When we talk about intermediate systems, we are generally referring to those that exist between two different entities and have the ability to facilitate communication or interaction between them. Some common synonyms for intermediate system include intermediary, mediator, go-between, liaison, conduit, bridge, connection, and link. These terms all capture the idea of something that serves as a middleman between two other objects, people, or systems. Whether it's a physical connection like a bridge or a more abstract one like a liaison, intermediate systems play a crucial role in connecting disparate elements and making the flow of information or resources between them smoother and more efficient.
