Cohesion is a measurement of the functional stamina of a component. A component with high communication and reduced combining is functionally independent of other modules. Below, functional independence implies that a cohesive component executes a single operation or function. The coupling implies the general association in between the components. Combining counts on the information provided with the user interface with the complexity of the user interface in between the components in which the referral to the section or component was created.

It is exceptionally relevant when both components trade a great deal of information. The degree of coupling between two modules relies on the complexity of the user interface. For more details, please describe the following write-up Coupling and communication.
