OSI Reference Model function is in the bit stream transmitted between devices.

OSI Reference Model from the different devices to communicate between applications in a service request and response form.

OSI reference model provides network services through the application process, providing inter- application communication is.

Similar to the OSI model, TCP / IP model uses the same hierarchical structure. TCP / IP model is divided into a level.

TCP / IP model and OSI reference model, the difference is that TCP / IP to the OSI model are included in the application layer.

TCP / IP model layer using the PDU (protocol data unit) to exchange information with the TCP transport layer header of the PDU is called.

TCP / IP model specification data transfer rate, maximum transmission distance.
