Open Systems Interconnection Specification

From Wikipedia, the free encyclopedia

The Open Systems Interconnection Specification (OSI)--Protocol is the lowest level of abstraction within the OSI standards scheme.

Each OSI--Protocol Specification operates at a single layer. Each defines the primitive operations and permissible responses required to exchange information between peer processes in communicating systems to carry out all or a subset of the services defined within the OSI--Service Definitions for that layer.
