Cohesion is a dimension of the practical stamina of a component. A module with high communication and low coupling is functionally independent of various other modules. Here, functional independence suggests that a natural component carries out a solitary operation or feature. The coupling implies the general organization between the components. Combining counts on the details supplied via the user interface with the complexity of the user interface in between the components in which the recommendation to the section or module was developed.

It is remarkably appropriate when both modules trade a whole lot of details. The degree of coupling in between 2 components depends upon the complexity of the interface. For more details, please refer to the following short article Coupling and cohesion.
