What's going on everybody!
Welcome to today's video on the network
plus exam preparation.
Today is the ninth video and we are going to be talking
about TCP and
IP. In this video, I'm gonna be talking
about. First, the overview of
the model. Then I'm gonna be
talking about the network interface.
Then I'm gonna be talking about
the internet layer, yes, I'm waiting
for the video to play to. And then lastly,
I'm waiting for the transport layer. Waiting for the
transport layer? I'm talking about the transport layer.
And then I'm gonna be talking about the application
layer. So we already talked about the
OSI model. Now we have to talk about
the TCP/IP
model. And these two models are very
simular. Of course, the TCP
IP model is just shrunken down into two
different sections instead of the three. Instead of the seven,
sorry. But it works the same way. The
network interface, level 1 is pretty much the same as the
first two layers of the OSI model
and so on. It matches up with the pictures.
Just follow that.

[Music]. The network
interface of the TCP IP layer
is all the physical equipment.
Such as ethernet, FDDI
and so on and so forth.

The internet layer is where
IP and ARP which is
address resolution protocol which is
responsible for turning things such as
the IP address into physical addresses or
DCL addresses. Again,
this is not a networking course so I'm not gonna get into
the full detail. So take the networking course if you have no
idea what I'm talking about right now.

The transport layer is where TCP and
UDP, which we already talked about, is the user
datagram
protocol is that this is where the information
is then transported off
into the world.

The application layer is where the
actual application is from. And it
includes alot of protocols.
HTTP, SMTP,
DNS, HTTPS
so on and so forth, so many
that we really don't care.
[Music]
[Music]. Let's recap. The first
layer is the network interface which has all the
physical devices such as ethernet
and so on. The second layer is
the internet layer which includes the
IP and the ARP
protocols. The third
layer is the transport layer which includes
TCP and UDP
and last is the application layer, which includes
alot of protocols.
So you don't really need to know the
function of each layer. However you do need to know the
certain protocols that work within each one.
So that's it for today's video
tune in next time for when I'm gonna be talking about
not really sure yet. Oh well,
I make it up as I go along. At least for this series.
So, tune in next time
