Dialog Control is the main function of Session layer.
Session layer manages dialogs between two computers and it is responsible for communication or conversation.
There are three forms of dialog.
1. Simplex dialogs : one way transfers, for example.. computer to printer ( computer will send data to printer and printer will receive the data ).
2. Half-Duplex Dialogs - Two-way transfers, Each device must take their turn. Both cannot transfer at the same time. for example..walkies-talkie
3. Full-Duplex Dialogs - Two-way simultaneous data transfers. Each device has it's own channel. for example.. telephone.

What are differences between the Session layer and presentation layer of the OSI model?
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.
