OSI
Standard legislated by official recognized body. (ISO)
The OSI reference model was devised before the protocols
were invented. This ordering means that the model was not
biased toward one particular set of protocols, which made
it quite general. The down side of this ordering is that
the designers did not have much experience with the subject
and did not have a good idea of which functionality to put
in which layer.
Being general,the protocols in the OSI model are better
hidden than in the TCP/IP model and can be replaced
relatively easily as the technology changes.
Not so widespread as compared with TCP/IP. (complex ,
costly)
More commonly used as teaching aids.
TCP/IP
Standards adopted due to widespread use. (Internet)
The protocols came first, and the model was really just a
description of the existing protocols. There was no problem
with the protocols fitting the model, but it is hardly
possible to be use to describe other models.
“Get the job done" orientation.
Over the years it has handled most challenges by
growing to meet the needs.
More popular standard for internetworking for several
reasons :
relatively simple and robust compared to alternatives such
as OSI
available on virtually every hardware and operating system
platform (often free)
the protocol suite on which the Internet depends.
