TCP/IP consists of four layers: link, IP, transport, and application layers. The OSI model consists of 5 layers. So, where is this question coming from? Observation, or just what...?


OSI model 7 layers
Application, presentation, session, transport, network, datalink, physical

Tcp/ip 4 layers
Application, transport, network, datalink

Some of the sytems(like cisco) use 4 layers for tcp/ip but some of them use 5 layers (Application, transport, network, datalink, physical). It totally depends upon the protocol developed by the system.


rubberman you don't have any idea about networking..so just stop replying.


@sdtechi :-) Thanks for the correction. Senior moments, brain farts! You are 100% correct about the 7 layers of the OSI model. But 5 layers are so much simpler! :lol:

And remember that old saw about "standards" - the nice thing is that there are so many!

sdtechi leave him alone!
OSI is a standard model and it has 7 layers. Which is taken worldwide..As i say before you just don't talk anything about networking.. shut your mouth

@sdtechi - regarding your comment about rubberman. First, you come across as being very rude and arrogant. Second, I guarantee you that rubberman has a lot more knowledge about networking that you do and I don't even know him personally.

If you understood that these models are purely conceptual, you wouldn't be asking these questions. The number of layers isn't really that important. The idea behind the models are to illustrate where and how protocols are related to one another in the TCP/IP communication process. The layers also provide a way to organize similar protocols that perform a similar service.
