Additionally, the session layer is responsible for terminating sessions between software processes.

Session layer establishes, controls and ends the sessions between local and remote applications.(tracks the dialogs between multiple computers)
According there name it going to build session between source & destination like when we are opening any site on browser then it's responcebale to create a back to back connectivity with destination point for us. And it is 5th layer of OSI model.
The main role of seesion layer is managing and setting up the data,
