The main theme of dividing the protocol into layers is to explain the rules of each layer specifically. This helps in putting various functions in separate modules and at the same time hiding the details of what they do and how they do it from other layers. This way we could improve the performance of one function or even change it all together, without having to change the whole protocol stack.

∙ 14y agoThe TCP/IP networking model was developed together with the TCP/IP protocols. It is a good description of these protocols. For example, if you use the 7-layer OSI model, some layers don't have an "independent existence" in the TCP/IP protocols - for instance, the TCP protocol is usually associated with layer 4, but layer 5 (sessions) are also handled by this protocol.

Which one is the best model between osi and tcpip and why?
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.
Compare the osi model and tcp-ip model and their associative protocols?
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.
Why is tcp combined with ip?
TCP and UDP are considered transport protocols (layer 4 of the OSI model). They were developed in conjunction with IP (routing - layer 3). Since they were developed together they were also designed to function together. Well the above answer is not up to the mark. Tcp is combined with ip because of following reason:- TCP in TCP/IP ensures that data is broken into packets and provides surety of end to end transmission . While IP in TCP/IP uniquely identifies the hosts on the network . So combining the both protocols ensures that data is transferred completely and among right hosts
Which company developed the tcp ip protocol?
DOD
What is the sub protocol that enables tcp ip to internetwork?
Both TCP and IP are subprotocols in the OSI model. IP is used for routing purposes, whereas TCP is used for transport control. If you are asking primarily about internetworking then it would be the IP protocol.
When transferring a file using FTP what is the order of protocols from the upper layers of the TCP IP model to the lowest layers?
FTP uses TCP, which uses IP
Who developed the TCP-IP model?
Dr. Vinton Cerf in 1973 while teaching Electrical Engineering and Computer Science at Stanford University. The Department of Defense. DoD
What differences between TCP and IP?
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.
Why tcp ip was adopted instead of osi 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.
What is the difference between osi and tcp model?
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.

What is layered architecture?
layered model architecture is tcp/ip model .you can reference this model as layered model architecture protocol.
Why Internet and its protocols is prior over 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.
