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.

What is a tightly coupled system?


It is a concept of system design and computing where every hardware and software components that are linked together in such manner that each component is dependent upon each other.


For example, in a tightly coupled system when a dependent class contains a pointer directly to a concrete class which provides the behavior of the object.


Tightly coupled architecture promotes interdependent applications and code. 


Tightly coupled architecture is fragile as the minor issue in one segment can bring the whole system down.
