The session layer is meant to store states between two connections, like what we use cookies for when working with web programming.
The presentation layer is meant to convert between different formats. This was simpler when the only format that was worried about was character encoding, ie ASCII and EBCDIC. When you consider all of the different formats that we have today(Quicktime, Flash, Pdf) centralizing this layer is out of the question.
TCP/IP doesn't make any allocation to these layers, since they are really out of the scope of a networking protocol. It's up to the applications that take advantage of the stack to implement these.
The layer that translates application layer data to an intermediate form that provides security, encryption, and compression for the data

The Application layer The Presentation layer The Session layer
There are three layers in between the network layer & application layer on the basis of ISO-OSI refference they are given below 1:Transmition layer 2:Session layer 3:Presentation layer
Application Presentation Session
The network layer. # Physical # Data Link # Network # Transport # Session # Presentation # Application
physical layer Data Link Layer Network Layer Transport layer session layer Presentation layer Application layer
presentation layer is used
The session layer (layer 5)
There are 7 layers in the OSI model which are from top to bottom: application layer / presentation layer / session layer / transportation layer / network layer / data link layer / physical layer
The three layers that I could think of are User interface, Client side, and server side.
