OSI is the Open System Interconnection reference model for communications. OSI as a
whole never succeeded in the marketplace, although some of the original protocols that
comprised the OSI model are still used.
Well, the OSI model now is mainly used as a point of reference for
discussing other protocol specifications.


The OSI reference model consists of seven layers. Each layer defines a set of typical
networking functions.


Today the OSI model can be used as a standard of comparison to other networking models.

Not all TCP/IP layers correspond to a single OSI layer. In particular, the TCP/IP network
access layer defines both the physical network specifications and the protocols used to
control the physical network. OSI separates the physical network specifications into the
physical layer and the control functions into the data link layer. In fact, many people think
of TCP/IP as a five-layer model, replacing the TCP/IP’s network access layer with two
layers, namely a physical layer and a data link layer, to match OSI.



The upper layers of the OSI reference model (application, presentation, and session—Layers 7,
6, and 5) define functions focused on the application. The lower four layers (transport,
network, data link, and physical—Layers 4, 3, 2, and 1) define functions focused on end-
to-end delivery of the data.
