Understanding the Five-Layer Architecture in Networking Networking plays a critical role in connecting devices and enabling seamless communication across the globe. One of the most prominent concepts in networking is the layered architecture, which organizes communication functions into structured layers. This blog will delve into the five-layer architecture model, tracing its evolution, describing its layers, and illustrating its practical application with an example. The History of Layered Architecture: From Seven to Five Layers The seven-layer OSI (Open Systems Interconnection) model was initially developed in the late 1970s to standardize communication systems. Despite its detailed framework, it became overly complex for practical implementation, and most networking systems gravitated towards the simpler five-layer model. The five-layer model combines some of the OSI layers while maintaining the core functions, making it more pragmatic and widely adopted. The key parties behind...
