Question 6Modules A and B both rely on global data or a global variable. This is an example of what type of coupling?1 pointTight content couplingTight external couplingTight common coupling
Solution
The answer is Tight common coupling.
Here's why:
Coupling refers to the degree to which one module (or component) of a system depends on other modules. In the context of software engineering, lower coupling is generally more desirable as it promotes modularity and the separation of concerns, making the system easier to understand, modify, and test.
Tight common coupling occurs when multiple modules share the same global data or global variables. This is considered a high level of coupling because a change in the global data can potentially impact all the modules that depend on it. This can make the system more difficult to maintain and more prone to bugs.
