The primary function of the transport layer is to build a network layer to provide the transportation.
The application layer provides applications with standardized data exchange.
This layer includes applications or processes that use transport layer protocols to deliver the data to destination computers. The internet protocol suite tcp ip and the osi model. It is used to develop network based applications. While tcp ip is the newer model the open systems interconnection osi model is still referenced a lot to describe network layers.
