Why there is gap between coupling?

A gap between coupling refers to a disconnection or inconsistency in the relationship between different components or systems, often due to differences in design, communication protocols, or operational goals. This gap can arise from a lack of standardization, leading to incompatibility, or from insufficient integration efforts. Additionally, varying levels of complexity and abstraction in coupled systems can contribute to this disconnect, making it challenging for them to interact seamlessly. Addressing these gaps often requires careful design, effective communication, and alignment of objectives among the involved components.
