I am having trouble finding out in which OSI Layer does the ultimate sender and receiver of data make contact?

Hi,

It's been a while since I looked at the OSI, but from memory it is the session layer.

Layer 5: The session layer...This layer sets up, coordinates, and terminates conversations, exchanges, and dialogs between the applications at each end. It deals with session and connection coordination.

cheers

the ultimate sender is of course layer 3 . The network layer . TCP puts info about the source and destination , ip puts more fcs ( control check ) and port info . the destination knows where and from which port the request or data came from and answers to the sender ip address and port related to the contacting application.
