Question

What is functional cohesion?

a.

The elements are grouped into modules in a haphazard way

b.

The elements realize tasks that are logically related

c.

The various elements of a module are independent but they are activated at about the same point in time

d.

All elements in a module with functional cohesion contribute to the one single function of the module.

Posted under Software Engineering

Answer: (d).All elements in a module with functional cohesion contribute to the one single function of the module. Explanation:Functional cohesion is a type of cohesion in software design where all elements of a module contribute to a single, well-defined function of that module. In other words, all elements of the module work together to achieve a common goal. The function is often one of transforming a single input data into a single output data. Examples of functional cohesion can include mathematical subroutines or modules such as "execute the next edit command" or "translate the program given." This type of cohesion is considered to be one of the strongest levels of cohesion.
