Comparison of OSI Reference Model and TCP/IP Reference Model Following are some major differences between OSI Reference Model and TCP/IP Reference Model, with diagrammatic comparison below. OSI(Open System Interconnection) TCP/IP(Transmission Control Protocol / Internet Protocol) 1. OSI is a generic, protocol independent standard, acting as a communication gateway between the network and end user. 1. TCP/IP model is based on standard protocols around which the Internet has developed. It is a communication protocol, which allows connection of hosts over a network. 2. In OSI model the transport layer guarantees the delivery of packets. 2. In TCP/IP model the transport layer does not guarantees delivery of packets. Still the TCP/IP model is more reliable. 3. Follows vertical approach. 3. Follows horizontal approach. 4. OSI model has a separate Presentation layer and Session layer. 4. TCP/IP does not have a separate Presentation layer or Session layer. 5. OSI is a reference mode...

The TCP/IP Reference Model TCP/IP means Transmission Control Protocol and Internet Protocol. It is the network model used in the current Internet architecture as well. Protocols are set of rules which govern every possible communication over a network. These protocols describe the movement of data between the source and destination or the internet. These protocols offer simple naming and addressing schemes. Overview of TCP/IP reference model TCP/IP that is Transmission Control Protocol and Internet Protocol was developed by Department of Defence's Project Research Agency (ARPA, later DARPA) as a part of a research project of network interconnection to connect remote machines. The features that stood out during the research, which led to making the TCP/IP reference model were: Support for a flexible architecture. Adding more machines to a network was easy. The network was robust, and connections remained intact untill the source and destination machines were functio...
