Well, hello again.
And now we have the ozone and dissipate IP models, and here gives us the explanation that I told you
before to remember in the layer that multiplexing, what is the multiplexing?
Is it sending different communication on the same circuit and also increase the reliability of communication
segments?
Can we use different circuits and only missing segments in case of their loss should be transmitted
again?
What are busy?
So basically, they are talking about this, which what is this which are?
Oh, I'm going to what is this, which is which is when we have a line and what is line?
It is a local area network.
And here is this, which this is the logo of the switch.
And this is the server.
Here are the computers and an IP phone.
So when we have this which.
This, which is a multiple ports with one with one.
And remember this very.
And remember it very carefully.
We have one port as an entrance and 24 at least ports as exits.
So we take the information from that one port.
It could be a rotor.
And in this case, we have a server webserver.
And we should we should multiply, transfer the messages and every message is different from the other
end or it can be sent to the users, which are these computers?
This is what multiplexing is about.
And they are present in the different communication on the same circuit.
This is what we said.
It's a grisly ability of communications on the missing segment.
They can be transmitted again, nowhere the size of the network.
What can we say?
About or have you ever heard about one or one?
Here we have the line, we already explained that it is a local area network when we don't use our outer.
So this is a did I'm going to get I'm going to give you a tip so you can be it more smart how to deal
with with such things, it takes some experience, but this is why we are here, why we are here.
So when you see a A.
A network without a realtor.
Different, there is a lot is a local area network, a local network means a local network typically
spend single geographic area.
Exactly, yes.
And provide services and applications to the people within a commune organizational structure, such
as businesses, Gompers regions that will basically that.
Are you saying when we have a network?
That you a kill.
We have a network that we connect with each other with a cable, and that cable is RJ 45 or RJ 11,
or it can be that.
I don't know any cable.
And what is why?
What is what it is a wide area network.
Wide area network here, we can use it, Rogers, when we see there's Rogers between two two lines and
two local area networks, we use that draw outdoors.
That means you are connected, different, different.
They can be the same, the same network, but they are in different location.
That means you are going to use a wireless connection.
I'm sorry there is a mistake here, one wireless area network, not wide area network.
I'm going to correct this.
Wireless.
Worms.
Area Network.
We should remember here we have a wider area and it's not wide, and it's it means we're a company or
organs.
That organization has location separated by a large geographical distance.
As I explained before, it may be necessary to use telecommunications services or telecommunications
service providers, you know, for telecommunication to interconnect a local area network in different
locations.
That means are going to use a a provider, a telecommunications service provider to give us a private
wireless IP address or a wireless network so we can communicate with each other in a secure way.
We are going to what we are doing this while we are doing all of this, the complications just.
For a secure communication or for a secure transfer.
And now we are going to see you next.
