Explanation:
“The Session layer (layer 5) is responsible for establishing, maintaining, and terminating
communication sessions between two computers. The primary technology within layer 5 is a
gateway. The following protocols operate within the Session layer: Secure Sockets Layer (SSL)
Network File System (NFS) Structured Query Language (SQL) Remote Procedure Call (RPC) The
presentation layer (layer 6) is responsible for transforming data received from the application layer
into a format that any system following the OSI model can understand. It imposes common or
standardized structure and formatting rules onto the data. The Presentation layer is also responsible
for encryption and compression.” Pg. 79-80 Tittel: CISSP Study Guide.
