Coupling

Coupling is a fundamental concept in software engineering that refers to the degree of interdependence between software modules. It is a measure of how closely connected two or more modules are, and how much they rely on each other to function correctly. In a software system, modules can be coupled in various ways, such as through shared data, control flow, or message passing. The level of coupling can have significant implications for the overall design, maintainability, and scalability of the software. Tightly coupled modules are highly dependent on each other, making the system more rigid and harder to modify or reuse. Loosely coupled modules, on the other hand, have minimal dependencies and can be changed or replaced with minimal impact on other parts of the system. Software designers often strive for loose coupling, as it promotes flexibility, modularity, and easier maintenance. However, achieving the right balance of coupling is crucial, as completely uncoupled modules may not be able to work together effectively to fulfill the system's requirements. Different coupling types, such as data coupling, stamp coupling, control coupling, and common coupling, are identified based on how modules interact and share information. By understanding and managing coupling, software engineers can design more robust, adaptable, and maintainable systems
