Definition
A module is a self-contained component of a larger system. 🧩 It can be a physical unit or a software component. Think of it like a Lego brick that fits into a bigger structure. Unlike a monolithic system, a modular system is easily customizable and expandable. Modules promote reusability and maintainability. They are used in a wide range of fields, from engineering to computer programming. Modularity simplifies complex systems.
