This layer provides netwrok services to the users applications, and does not provide services to any other OSI layer.
Application Layer
-
Application Layer (name 5)
- 1 - Layer 7 OS
- 2 - closest to user
- 3 - No services to any other OSI layer
- 4 - establishes availability of intended communication partners, synchronizes agreement on procedures for err rec and control of data integrity.
- 5 - OSI Layer 7
-
Ensures the information that the application layer of one system sends out is readable by the apllicationlayer of another system.
