And hello again, last time we stopped here on this page that we have the comments to know in our our
DNA, in our computer.
I mean, let's let's give an example, let's put this this graph or matter of fact, this put this government
and we are going to open our and.
Our command prompt and also you should know something about Windows and Linux capital letters should
always take capital and lowercase letters always say that the work is like we have this on Windows and
Linux, but on Cisco packages, it doesn't matter.
It's like capital or not.
So let's do this.
Come on and look up.
And here we have our default server, which is the NSA, that Google and its address is the public address
of Google, which is 8.8.8.8.
Now let's see what we have there.
Here we have the server.
The this is the description of the server that it was a logical system to create a database to ensure
name resolution.
This is right.
At the top of the hour, she wrote, service servers give records about how to reach top level domain
servers, which which in turn have record pointing to second level domain servers and so on.
We have in this in this place, which is a.
Mainly mainly, you don't study it on networking, but you study it on the networking at Linux or networking
at Windows because there is there is a difference.
And second level domain servers, we call them slaves and the first domains are we would call them masters.
We have a an air show in the inner service that is called master slave.
We are going to see it.
We are going to see, but it is not going to be in this course.
And then they see the different top level domains.
These are the following types like generic sites like dot com that or dot net and foreign nationals
like that that's par for France, that the UK, for the United Kingdom, that us, for the United States,
that is for Morocco.
And then we have the SDP server and protocol.
The server is simply for the web is we.
We have like every website, we have this HDP.
Double dots.
Slash slash.
Then we have the WW W Dot, the name of of the website, then that compass the World Wide Web.
This w w w stands for World Wide Web.
Anyway, is DTP is for is for it.
So as as an example, the browsers start interrupting this three parts of the URL sgp, which is the
protocol or the Typekit.
Sometime we'll have the Prius, which is another protocol.
Just it is more secure.
There is the S10 for security.
Like here we have the example of the school.
Now we have the Bob, and it seems to be the Pope and MGP are similar to the FTB, but the F2P is four
five and MGP is four mrJ or males, females and pope.
I think it's MGP said that for a simple mail transfer protocol and bob, it is for the.
Around the office.
Yes, it is for the post office protocol, I think.
And here.
As we can see, they say that MGB is used for a fair, transparent in emails and Bob is for transit,
for transfer, transfer and that's.
Application layers protocol.
Oh, here we have the description.
They say images requires multiple applications and services, both of his protocol, as I said, which
is pop and simple measures of protocol as MTV are two applications layer protocol.
We saw that in our first video of layers.
The protocol has specific purposes to allow the user to pick up his email or his made from the horse
that does not contain his movements.
So the difference between as A.B. and Bob is MGB should be in the in the network and Bob, it's going
to be outside of the network and you can still use it.
Thank you.
