TCP/IP Model This lesson gives a brief overview of the TCP/IP Model. This model has four layers: - Network Interface - Internet Layer - Transport Layer - Application Layer These layers work together to perform network communications.

Now that we've talked about Roos I model, we also need to talk about our t c p i p model now r T c P I P model is actually a
more broad view of our OS I model t c p I p model describes
are networking in a series of layers just like Roos I model does. However, if we take a look at our t c p i p model and compare it with roos I'm model r T c P I P model is going thio have layers which encompass a couple of our different OS I layers. So
if we know our t c p r. If we know Roos, I model in depth. We can use that knowledge to better understand each of our T c P i p layers. So let's take a look at it. We'll go ahead and take a look at a T c. P a p model what each of its layers encompass on roos I models.
And then after this will take a little bit of a in depth look at our T c p i P layers individually.
So our t c P I P model our network interface layer is our first layer, followed by our Internet layer transport layer and then application layer. These work just the same way as R. O s I model does in that each layer works together and perform network communications
and our t c P I p model our network interface layer is going to be referring to on our OS. I'm model what we have as our layer one our physical layer and layer to our data link layer. So network layer our network interface layer in T c p I P model is going to be layer one and later to our OS I model.
Our Internet layer is going to consist of layer three. Our network layer from Roos I model
our transport layer is going to directly correlate with our transport layer on R O s I model
and then our applications layer is going to be our biggest chunk of roos I model r T c P I P Applications layer is going to include our layer five session layer layer six presentation layer and layer seven application layer. So we know now how are layer r T c p I P model correlates with Roos I model
So let's take a look at another pneumonic in order to help us. Better remember it
Now we're going to stick with our food theme here. So are our t c P I. P model is going to be in I t a never ingest toxic apples and then roos I model Please do not throw sausage pizza away. So we're sticking with the food theme.
Please feel free to in our forms or in our discussions,
offer up different ideas as faras Different new Monix The TCP I P model is a little bit easier to remember without the pneumonic just because it's shorter and there's less parts to remember. So
that's how our T c, P, i, P and O S I models correlate. Let's go and take a look a little bit in depth at each individual. T c p i P layer
