Module granularity refers to the level of detail or size of a software module. A module can be a small function or a large subsystem, and its granularity determines how specific or general its purpose is. Higher granularity modules are more specific and focused on a narrow task or function, while lower granularity modules are more generic and cover a wider range of tasks. Granularity is important in software design as it affects the complexity, maintainability, and reusability of the software modules.
