Hello again.
Well, as we knew, the difference between local area network and wireless area network and are going
to address them as LAN or Wan lent when.
And now we are going to see the hard work composed of a network, what is what, what can we touch the
stuff that we can touch?
Now we have and devices and also hosts what are our hosts?
They are a form of interface between the human network and the underlying communication network is through
a computer network printer.
Epiphone and Surveyor surveys a surveillance camera.
By the way, my small little, not me, my end of the year project when I was in school, it was about
the device before it was both connected to.
Two different machines.
One used Linux and the other is Windows seven.
Back in the day.
And I had to install the secured network and also a VIP thorn in the Linux was going to be the the main,
uh, the main person to go all the client, which was the windows.
And you can you can see I have the detailed information about how to make a VIP phone between Linux
and and a Windows in my neck that date.
I'm going to put it on description and now we have the intermediate devices.
What are the intermediate devices such as hops, switches, wireless access points, wireless routers,
browsers, firewalls?
These are the devices.
That conduct.
The network with each other.
That connect the main thing to the user and the main thing or the mean machine is basically the server,
so very is is everything and you, the user, is the whether it is the client or the, I don't know,
the agent, the person with the computer and between the server and the computer we call them, we call
all the things that in between the intermediate intermediate devices.
And then we have the network supports it as the metal wires, optical fibers, wireless transmissions,
the distance over which media can probably properly carry the signal.
The hero are going to use a protocol, which is which is called the.
You are going to use a protocol which is called a.
Eli, are big.
And here.
The amount of data transmissions are going to use a protocol that is called the Oh, let's b is I'm
giving you this.
Do stuff so you can know about because it is in the invented and advanced part of learning, networking
and physical package.
Is it because it is?
It is something very little to your own such and such such stuff because of the media installation.
Yes, we are going to always be here.
I know you are going to learn divisive symbols and network supports.
Basically, the we have them here, we have them here.
And each I mean, the voice.
And when you click on, I come in, give us the multiple the voices in the same.
Type of device.
I'm going to give you an example, such as you have the rotors, a rotor overalls.
We are going to use very, very much in our cars.
We have this simple Wrangler.
I'm so sorry about this.
And then we are going to use the wireless router.
And we are going to use the.
Basically, this this is everything.
I'll go into the water and the water shelter.
I am going.
I am going to put the project where the ground terminal.
Maybe in the end, because it is very high experience level.
And we are going to see the other side of it.
We have heard the hubbub this is we're having to switch.
This is the icon of the switch.
We've talked before then we have here at the hub, this stupid device, as we we mentioned before,
we call it stupid or less work than we have here.
The server IP phone, the firewall, the laptop, the computer basics.
You have the access point, the wireless access point.
We we have the wireless router.
The wireless router is very interesting to learn about in Cisco Pocket router that it experienced.
If.
Then we have that wireless connection.
This this is the thinking of the wireless connection between two networks and this is the the the local
connection or the local area network connection and Cisco Bucket.
Here we have the wireless connection.
The difference between these two, this is for a one wireless area network, and this is going to it
can be outside a one area network because we're going to have cases when we have network and just one
computer with a with a with Iran, and we called it a we were not going to with anything.
It's going to be just a computer that is, it's going to be a client by by the internet or something.
We use this type of of connection so we can.
We can mention it's in our pocket raised.
Here we are going to see the Composantes, the software composantes.
And the layered model already talked about, and there are the protocols and they are the layers.
So what we are going to see next is the message, I'm sorry.
Here we have the network addressing, as I told you, the thing that we call the message and we called
specifically in networking and elections.
Here we have it, here we have the physics part, the physical part and then the datalink, then the
network, then the transport, then the top players, the other three layers that we talked about.
And in every and in every part, you are going to have between eight or 16 zeros and ones and every
eight and 16 zeros and the ones means iMessage, and we are going to see that later.
