Why has the internet model replaced the open system interconnection reference model?

Answer 1

Because internet model uses less layer which would take less time for the data to pass through

Answer 2

: The Internet model is simpler (effectively collapsing the top three layers of the OSI model into a single

model) and easier to remember and understand. Further, the ISO OSI Reference Model is the result of a formal

standardization process and is technical in its presentation. By contrast, the Internet model is appropriate for those

within the networking community with practical needs related to implementing the Internet and networking.

However, only a few years ago the Internet model was commonly understood to have only four layers. Today, the

transport layer is now separately identified in the Internet model, yielding an important, fifth layer for

comprehension. This evolution in presentation may show that at least one technical distinction from the OSI model

is now considered practical as the scope, volume of traffic, and complexity of networking (and of the Internet)

grows.
