Layered Network Architecture is a type of architecture that splits the functionality of a computing system into different layers. Each layer has distinct responsibilities and interfaces, allowing for modular design and improved maintenance. Commonly seen in both networking and software engineering, this architecture enhances scalability and interoperability. For example, the OSI (Open Systems Interconnection) model divides networking into seven layers, from physical to application, making it easier to troubleshoot and implement changes without affecting the entire system.
