Final answer:
Low coupling and high cohesion are two important principles in software development that lead to more modular and maintainable systems.
Step-by-step explanation:
Low coupling and high cohesion are two principles that are often discussed in software development. Low coupling refers to the degree of interdependence between different modules or components in a system. It is better to have low coupling because it allows for better modularity, flexibility, and ease of maintenance. High cohesion, on the other hand, refers to the degree to which the elements within a module or component are related to each other. It is better to have high cohesion because it promotes code readability, reusability, and maintainability. Therefore, low coupling and high cohesion are preferred in software development as they lead to more modular and maintainable systems.
