Question

How is information hiding related to cohesion and coupling in design?

a.

It increases coupling between modules

b.

It decreases cohesion within modules

c.

It decreases coupling between modules and increases cohesion within modules

d.

It increases coupling between modules and decreases cohesion within modules

Posted under Software Engineering

Answer: (c).It decreases coupling between modules and increases cohesion within modules Explanation:Information hiding decreases coupling between modules and increases cohesion within modules. It increases cohesion as the module's secret binds the module's constituents together and decreases coupling as the module's secret does not permeate the module's boundary.
