Description: The external interface is defined as a point of interaction between a system and external entities or systems. This concept is fundamental in system architecture, as it allows communication and information exchange between different components, whether hardware or software. In the context of technology, the external interface may refer to APIs (Application Programming Interfaces) that allow developers to interact with a system and leverage its functionalities. In microkernel-based systems, the external interface is crucial for modularity and inter-process communication, as it enables different services to communicate efficiently and securely. The main characteristics of an external interface include its ability to abstract the complexity of the underlying system, provide standardized access to functionalities, and facilitate the integration of new components or systems. The relevance of external interfaces lies in their role in the interoperability and scalability of systems, allowing different technologies and platforms to work together effectively.
