Answer: Layered network architecture enables us a clear loosely coupled system with a definite distinction between the various layers visible.
Step-by-step explanation:
Layered architecture enable independent deployment of each of the different layer, so that emphasis can be laid to the layers in respect of their protocol deployment.
TCP/IP is a standard model which is being followed everywhere, however the OSI is a conceptual model. The TCP/IP is actually derived from the OSI model.
Both the models differ in the number of layers present in them.
TCP/IP has 4 layers whereas OSI has 7 layers.
