loosely coupled system

What is a loosely coupled system?

It is a concept of system design and computing where loosely coupled system is one in which every individual component has no knowledge of the definitions of other components.

In another meaning loosely coupled architecture or system means changes in one module / section that affect the other components and every module is somewhat independent of each other.

In a loosely coupled system, hardware and software may interact but they are not dependent on each other.
