Hello again.
And now are we reached the Port of Fire Transfer Protocol, which is which is the FTB.
And as you can see, community use application layer protocol was developed to allow file transfer between
a client and a server.
As you can see here in our in our image here to Joseph to transfer file correctly, we can we can see
the FTB required that two connection be established between the client and the server.
A control connection for command and response.
And other for the very transfer of files.
This is that requires all of the features of a file transfer protocol or the FTB protocol.
Now we have the most interesting and the most
interesting and the most, oh, I'm going to say it like essential protocol ever.
Which is the DHC Dynamic Host Configuration Protocol.
I mean, here we have the explanation.
It is very detailed, but I am going to give you my explanation like.
Sometimes some things that I'm going to see it from my heart and some things that will make you understand
how important is the protocol basically in our our description here, they say the servers enable devices
on a network to obtain the IP configuration, IP addresses, subnet mask, get away and other IP settings
for defined duration.
Please.
After the plane disconnected, the IP address is released and it can be used by other declined.
They simply don't pose a security risk because any device connected to the network can be received and
address it because of this.
In most cases, the ACP is used for any other devices and static addresses for getaways, which are
servers and printers.
What does it say, description?
Simply, it says that in a network, we have multiple machines.
And there's multiple machines could be a is a client that works from a distance.
It's going to be a local area network like we have here at the server.
It's going to know.
We can as.
I'm going to give you like myself, I'm a technician like I'm a senior technician in networking, like
I'm going to have a LAN log in the door.
I can apply to all these machines and static static IP addresses, but it is dangerous.
Is strictly dangerous if a user like like, I don't know, because I'm going to go in in another way
and I'm going to tell you something about cyber security, sometimes we have, we have employees that
can be it can be a danger for our local area, network security or for the network security because
they can take our IP address and they can hack it or send it to any hacker.
We have that.
We have that on cybersecurity.
So.
This is just one case.
There's other cases, but for more security, we applied ECP protocol, the AC protocol.
We give him, we give him a pledge of addresses or a number of addresses, IP addresses of or hosts.
And he gives them to machines like in a in a way that's dynamic and it can change.
When the computer turned off and then turned on, it would change automatically, or sometimes it will
change for a duration, duration of time.
I think in Windows servers, they give eight days and they recall you would get the IP address would
change in the in the middle of the lease or use of that duration, which is for these.
And Lennox, I don't I don't really remember because basically when you turn off your computer and turn
inward, not it will change automatically.
This is the this is the the the main purpose of dynamical configuration protocol to the ACP.
It gives IP addresses or host machines in the network, and it would change them dynamically as soon
as it passes the duration or the mission is turned off and turned on.
Now we have a you can see one question well, what we can do for the server.
The server can't be turned off or still not.
It is not.
It should be turned on.
They'll always.
Further, the server we are going to apply is said to address.
Also for the getaways, which is which is we can we can see it is possible, but for the ever getaway
and printers there, they should have static addresses, then that means we're not going to use the
ACP protocol.
By the way, this isn't information.
Do you remember that place that is the starter with the IP address of one six nine?
We can I mean, I mean, computers give themselves just in case that we don't have a dealership.
Could they give themselves an IP address that is in the pledge of the one six nine address?
I don't I don't really remember that the phone address, but we are going to search that up.
We are going to associate IP the air.
196 that.
It's called Dora.
All right.
Hmm.
We have that.
This is very funny, but I think it is called Dora the O'Reilly, and you should you should have it
in this video.
I'm not going to go back because we already address that and see you in the next video.
