Module

A module is a distinct unit within a software or hardware system designed to perform a specific function or set of functions. In software development, a module is a self-contained component that encapsulates a portion of the program’s code, often with a specific task or functionality, and can be independently developed, tested, and maintained. This modular approach enables developers to manage complexity by breaking down large systems into manageable pieces, enhancing code reusability, maintainability, and scalability. Modules typically interact with other parts of the system through well-defined interfaces, ensuring that changes in one module do not adversely affect others. In hardware, a module refers to a physical unit, like a memory module, that can be integrated into a larger system to enhance or extend its capabilities.
