Cohesion is a measurement of the practical strength of a module. A component with high cohesion and low combining is functionally independent of other modules. Here, useful freedom means that a natural component performs a solitary operation or feature. The coupling implies the general association between the components. Combining relies upon the details supplied via the user interface with the complexity of the interface in between the components in which the referral to the section or module was created.

It is incredibly appropriate when both components exchange a whole lot of information. The level of combining between 2 components depends upon the complexity of the interface. For more information, please describe the following post Combining and cohesion.
