Hey mate ☺️

Session Layer :

– Network File System (NFS)

– Structured Query Language (SQL)

– Remote-Procedure Call (RPC)

– X Window System

– AppleTalk Session Protocol (ASP)

– DEC Session Control Protocol (SCP)

The session layer establishes, manages, and terminates sessions among applications. This layer is primarily concerned with coordinating applications as they interact on different hosts. Some popular session layer protocols are listed here, Network File Systems (NFS), Structured Query Language or SQL, X Window Systems; even AppleTalk Session Protocol is part of the session layer.

Presentation Layer :

The presentation layer is primarily concerned with the format of the data. Data and text can be formatted as ASCII files, as EBCDIC files or can even be Encrypted. Sound may become a Midi file. Video files can be formatted as MPEG video files or QuickTime files. Graphics and visual images can be formatted as PICT, TIFF, JPEG, or even GIF files. So that is really what happens at the presentation layer.

I Hope it helps you ☺️ ✌️ ✌️
