What is loose coupled?

Loose coupling is a design principle in computer science that promotes the separation of software components so that they may be developed, deployed, and updated independently of one another. It facilitates modular design, promotes strong cohesion of software components, and leads to reusable code. Loose coupling reduces the interdependency of components by using well-defined interfaces and protocols to communicate between them, without requiring knowledge about the internal workings of the other components. This approach ensures that changes to one component do not affect the entire system, making it reliable, scalable, and easier to maintain. Loose coupling is often used in service-oriented architecture (SOA) and microservices architectures.
