Layered Architecture Flashcards
What is layered architecture?
Layered architecture has been the standard approach to networking for many years because it enables you to break a very complex process into smaller processes.
How does the OSI model integrate this concept?
In the OSI model a range of complex processes is also split into separate layers to allow changes to one layer without affecting the next one. For instance, layer 7 of the OSI model, which is the application layer, is not concerned with what happens in layer 1, the physical layer. All that is required is that layer 7 receives the data in a format it can understand from layer 6, the presentation layer. Many things can change at each layer but as long as the input and output to each layer is correct the layers will continue to function.
