CompTIA Security+ Exam Prep

Answer: B - Coupling indicates how much interaction one module requires carrying out its tasks. If a module has low coupling, this means the module does not need to communicate too many other modules to carry out its job. High coupling means a module depends upon many other modules to carry out its tasks. Low coupling is more desirable because the modules are easier to understand, easier to reuse, and changes can take place and not affect many modules around it. Low coupling indicates that the programmer created a well-structured module.
