     The Transport Layer is a higher level layer on the Open Systems Interconnect model than the Network Layer. The Transport Layer is responsible for checking that data packets created in the Sessions Layer are error free. The Transport Layer ensures that the protocols operated at this layer provide reliable end-to-end flow and error control. The most common protocol that you would see at this layer is TCP/IP.
     The Network Layer is further down the OSI model and is the first physical control layer. It is responsible for logical addressing and translating logical names into physical addressing. That is converting a logical name like to a physical address like This is the layer that controls routing of data from source to destination plus the building and dismantling data packets. The first physical equipment at the Network Layer would be Routers, Bridges and Switches.
