One of the most widely used is the Transmission Control Protocol/Internet Protocol (TCP/IP). Also, a generic protocol model used in describing network communications known as the Open System Interconnection (OSI) model is useful for comparing and contrasting different protocols. 1.
So, when was the TCP IP model developed?
Several other TCP/IP prototypes were developed at multiple research centers between 1978 and 1983. The migration of the ARPANet to TCP/IP was officially completed on January 1, 1983, when the new protocols were permanently activated.
What year was the OSI model created?
The Open Systems Interconnection (OSI) reference model has served as the most basic elements of computer networking since the inception in 1984. The OSI Reference Model is based on a proposal developed by the International Standards Organization (ISO).
