What Does Loose Coupling Mean?

Loose coupling describes a coupling technique in which two or more hardware and software components are attached or linked together to provide two services that are not dependent on one another. This term is used to describe the degree and intent of interconnected but non-dependent components within an information system.

Techopedia Explains Loose Coupling

Loose coupling is primarily used in enterprise networks and systems to reduce the amount and intensity of risk found in highly dependent systems. A system with multiple components is less likely to have performance issues when those components are loosely coupled.
