This Component Diagram Tutorial divides a large object-oriented system into smaller components, making it easier to manage. It represents the physical view of a system that is contained within the node, such as executables, files, libraries, and so on. It depicts the relationships and organization of the system's components. It aids in the development of an executable system. A member is a single system unit that can be replaced and executed. A component's implementation details are hidden, requiring an interface to perform a function. It is analogous to a black box, the behavior of which is explained by the provided and required interfaces. It holds because it is a specific type of UML diagram.
