what is the difference between osi and tcp ?

Answer Posted / nathan

OSI is a standard "reference model" that describes how
protocols should interact with one another. Invented by the
Department of Defense, TCP/IP became one of the "standards"
that enabled the Internet to become what it is today.
TCP/IP doesn't map cleanly into the OSI model.

OSI has seven layers and TCP/Ip has 4 layers.
