Can you explain the concept of strong cohesion in a system or module?

High cohesion means that elements within a module or class are closely related and perform a single well-defined task. This increases readability, makes maintenance easier, and supports code reuse.

An example of high cohesion:

• A class responsible only for managing users (creation, deletion, update).
• All methods and properties of the class are related to this task.

An example of low cohesion is when a class mixes functions unrelated to each other, such as user management and file processing.

High cohesion promotes better modularity and reduces the likelihood of errors during changes.
