Component

In software development, a component is a modular, self-contained, and reusable building block that encapsulates a specific function or set of functionalities within a larger system. It is designed with a well-defined interface, allowing it to interact with other components while hiding its internal implementation details. This approach promotes modularity, making systems easier to understand, develop, test, and maintain. Components can range in granularity from a simple UI widget, like a button, to complex business services, like an authentication module.
