Once again, coming in network security, fundamental course, not in the model number two.
We understand the border was a mortar.
That hole was a model water, and that hope was a more lonelier work.
Now, when we start dipping into computer network science, the first thing we learn it usually ECPA,
BCB, IP protocols, water for down network connections.
Then internationally Stender organizations should die.
The protocol currently known as the open system interconnection or a protocol in.
That means all the data will be transferred according to the WHO is a modem.
There was a modem igy difference and basic concept of the tutee of how their protocol works.
Now let's say becomes a connection, a standard for the computer.
In addition, it was created.
Also Boothville fixed certain objectives.
Now let's say you had Silverleaf.
Each now had your functions and had their respective doors mean that you would only had a different
different functions and different different tasks.
Now, part we learned about which layer will be in the same order.
Now, first is not clear here.
Secondly, that datalink clear part is done at drug port is their transport pitted the Sesson Section
60, the project station and last seven is that application.
These seven layers are come in the same order with Fiji clear.
It used for the bill's transmissions and it's used the Internet, fiber and wireless protocol.
And in the hybrid part, it work on the husband, the repeaters, the hub and the printers are connected
with that.
Always say Pidgey can live now.
Secondly, that datalink clear data Letelier is responsible for.
The freeze means that if every bita, each not successful rassman then again, that the data will be
transferred.
And this is dependent on the datalink.
And depending clear it can with that it cannot.
And a.D.A these two type of protocol not connected with the datalink.
Clear.
And when we talk about the hardware part, then switch and bridges are connected with the data nuclear
powered.
And most importantly, it is that networking is network layer are responsible for interconnections of
the different different types of computers here.
IP, ICMP, IP X and the IP protocol log used in that Natera clear.
And the hardware part that the rotor is connected with the network.
When we talk about the data, then the whole kit will be saying that it's dependent.
Datalink, clear.
Next is dark transport layer in the transport layer.
We'll work on the BCB, UDP and SBX protocols and the segmentation parts of that data.
Each responsible doing the transport layer.
Next is the sets and lived since the late Zippel responsible for the internal host communications.
And it used a Bulldog and Winshaw protocols and the details depend on that sensor.
Next up, agenda should live.
That whole group agenda under Dindo to see what side.
So they had be Jebb Big J put MBG protocols out.
You did the presentation live and how we did Dedee Project Daejeon and encryption will be an independent
presentation.
Last is the application layer in the application.
Live it you toward the netbook process to applications.
And here we used that as TDP FPP or as empty B protocols.
So these are the same months earlier, which comes that same order.
No, we discussed the A one by one.
Now first is that physically nothing you can do is not first lab in the West Year near property first
model.
The responsibility is to transmit the WS.
It is done from the sender Fiji can live and a disk to that except Fiji.
Khalia mean that in the hardware side nuts and different lere sender.
And to see what our connection with that Fiji Callea next is that they don't include clear that they've
done LeClaire.
That's clear from the boten in.
That was a model which can garden white night films that contain data that detect atah and transmit
failer frames megadeath are also implemented in this layer.
Some devices such as done network interface card, layer to suite and network.
But it is also obreht here means that the.
Let is work on the frames.
Mean that if any data it failed to transmit, then it's again cosmic by that data link.
Next is that network.
Network Live has that Dosso defining IP address that.
How are we defined the IP based that is depends on the network layer.
Means that in every computer we have IP address.
And that is defined by that night directly.
These make each computer can be connected to one network network.
It also functions to give the old dog routine process and makes her less on existing day topic.
Is that how we make the pictures, how we transmit the speakers?
All I depend do not know directly.
Up next is that transport layer.
This man will break the daytime to break it and give the serial number to the data, pick it so that
they can be rearrange when they is that destinations means they're done.
That's how we bring that data is depend that transport layer and the receiver silverside how we collect
the data, how we collect up beakers in defending the transport layer.
In this layer we needed reminder protocol that we will use to transmit data.
Put a jumper DCP Protocol.
This protocol will send data, pictures, white also shooting there that big indigency successfully
and retransmitted big gauge that I load would be made in the middle of the road means that if any big
it will be lost in the transmitter or receiver side on the inside.
Then it again, it's transmitted by the transporter nasties that says and it says it literally define
how and connections can be made, maintain or destroy.
And these live there are name recombinations and Nafez or SMB crypto could mean that the three parts
that how we make the connections, how we maintain the connections on how we disconnect the connections.
D.R depend on the Sicilian and naturally dock project isn't there.
The budget is embedded responsible for Duckhorn meeting and delivery of information as to the application
layer for for the processing or display.
But then how will we display that data is depend on the agenda.
Chevallier 50 little application network consent regarding syntactical difference in detailed communications
between that and UJA system and at GIAMPAOLO up vegetation.
So this will be the convergence of that.
You BCB coded text computer file doing ASCII code.
It is not clear is the application layer, the application layer an obstacle layer that specify does
sered communication look good?
And Andrew Fierce method used by Kristiina Communications Network.
That application layer abstraction is huge in both the standard model of the computing networking that
internet protocol suit VCP AP and was a modern I'll do both more than use the same Thom's for data spec
to high used to live in layer that deal definitions and perfect are defense.
So friends.
This is thus seeking module of that network security fundamentals.
If you have any crealy then you can ask me now regarding the modular but tucked.
