1.The OSI model originally distinguishes between service,interval and protocols.
1.The TCP/IP model doesnt clearly distinguish between service,interval and protocol.
2.The OSI model is a reference model.
2.The TCP/IP model is an implementation of the OSI model.
3.In OSI model,the protocols came after the model was described.
3.In TCP/TP model,the protocols came first,and the model was really just a description of the existing protocols.
4.In OSI model,the protocols are better hidden.
4.In TCP/IP model ,the protocols are not hidden.
5.The OSI model has 7 layers.
The TCP/IP model has only 4 layers.
6.The OSI model supports both connectionless and connection-oriented communication in the network layer,but only connection -oriented communication in transport layer.
6.The TCP/IP model supports both connectionless and connection-oriented communication in the transport layer.,giving users the choice.

TCP/IP because the osi model has seven layer but in tcp/ip only four layers and most important is that the tcp/ip model is reduce the function of osi model.
Offcourse osi..... TCP/IP is an implementation of osi....
The OSI model came after TCP/IP networking protocols were available in networks. The OSI description also as to describe and identify networking components that do not exist in the TCP/IP model.
The OSI model encompasses all of the TCP/IP sub-protocols plus several other protocols that are not part of TCP/IP. These would include IPX/SPX, NetBEUI, Appletalk, and other proprietary protocols that are not part of the TCP/IP model.
•The layers perform the same duties as in OSI, however, OSI's top three levels are combined into the single Application layer in TCP/IP.•It carries out all of the same functionality as those three layers in OSI.—In simple terms is a language that enables communication between computers—A set of rules (protocol) that defines how two computers address each other and send data to each other—Is a suite of protocols named after the two most important protocols TCP and IP; but includes other protocols such as UDP, RTP, etc.—The OSI model is a model comprises of 7 layers.—The TCP/IP model only has 4.—In reality the TCP/IP model was developed around about the same time as the OSI model which is why it is inspired by it but does not completely conform to the specifications of the OSI model.—The TCP/IP model is a description framework for computer network protocols created in the 1970s by DARPA, an agency of the United States Department of Defense.
The OSI model is used today with current networking standards. It covers more than the more limited TCP/IP model.
tcp is the transport control protocol and ip is the internet protocol. tcp is concerned with guaranteed delivery of packets from source to destination, while ip is the protocol used to actually deliver packets. tcp is located at layer 4 of the osi model, or the transport layer. ip is located at layer 3 of the osi model, or the network layer. check out the video tutorials in the link below.
UDP or User Datagram Protocol works on the Transport Layer (layer 4) in the OSI model.
tcp ip and osi are having their reference models, they are not reference models.......they are network models, defines how does a network works when data is sent from one node to another within a network.
The TCP/IP model was adopted and condensed into 4 Layers.1. Link layer ( Layer 1and 2 of the OSI model)2. Internet Layer (Layer 3 of the OSI model)3. Transport ( Layer 4, 5 and 6 of the OSI model)4. Application ( Layer 7 of the OSI model)http://en.wikipedia.org/wiki/TCP/IP_model#Link_Layer
The OSI model is a simple framework for categorizing the different layers that make up network communication. There is no direct relation between the OSI model and any network address or protocol. In fact, most network protocols don't fit neatly in to the OSI model. TCP/IP, for example, spans the data-link, network, and transport layers.
