Now, let's talk about the history of the actual tree from Wales or ordinator.
So first those introduced this Andy Serwer, uh, new technology.
And with this, they have to do a separate operating system for Sarasate, for managing services, as
you can see.
This is called and Hoya's Operating System Network Operating System.
So this is installed on the Saraa computer, which has very powerful configuration.
And then in this server that we use to carry the information about the cranes and also cranes, request
the queries about some information and the server will do so.
It is introduced in the 1990s, I don't know particularly here, but just here is not a model.
So then what the hell is this empty invoice operating system on Windows Server then?
This, uh, invoice operating system has, uh, uh, limitations.
So that is, uh, it can only generate up to 40000 objects.
So whether if you want to create users or computers, printers, groups, etc., all you can do is up
to only 40000 objects on the water account you can create is part of the.
If your organization is small, then it's OK, if it doesn't is fine, but if any big, upper, big
organization wants to use this and then they have so much limitations because of 40000 objects may not
be sufficient.
So that's why what they have done is they have removed this invoice and they have created the extra
finder directory services.
So this supports more than part objects, and you can see here, this is the diagram, sorry for not
making PowerPoint presentation.
So this is the kind and connected to these servers, to servers.
We have extra funded servers and this client will ask for information using this directory access protocol,
and the server uses a directory service protocol.
So using the staff grant will connect to the server and coding for any information he wants.
So this is a very good one, actually founded it has overcome the limitations of this and its operating
system.
So the directory service is excellent.
So this expert finder uses all you say more as a reference.
So it's a model it uses for interaction and communication.
Then in the early 2000 or 1995, it was then this TCP IP model has been implemented in order to assist
all over the network.
So this became very tough, very tough to handle, and also better application or database replication
from one to another.
Server is very low across this extraordinary directory services.
So if the server wanted to send a database to the server and want to replicate.
So this takes more time.
So whenever you have so much of an application going on, then this is not considered as a good one.
So that's why they have implemented this and ended up stands for Directory Access Protocol.
So this is like Middlesworth between the client and the Explorer Finder, uh, server.
As you can see, the first client since using FDCPA because the computer using the user by the client
has been implemented that E.S.P.
So this request will be converted into the OSA model using this adultry access protocol, because all
of the computers and at the 2000 using this model so that the requested we can return to the Western
model because this already this layers will be understood by the actual vendor.
So that's where this ended up are they want to process have been installed on this, uh, middleware
server.
So to convert this VIP package, it's always separate.
So now the sex offenders understand the request and processes that request and send the response, so
this was verified.
So they have got much idea that to mix these two services.
So be sure we can remove this material and implement this in the server, then this accurately came
into place actually is like a phone book.
It is not any service to directory users and services.
So there is a recent update, uh, version three.
So this portion will be installed along with this actor to try to retrieve the phone.
It contains every other every object information and data.
And this that client access to this data using this services and also this to the tree will be will
I mean, they will ask for any other information on the client, the printers, computers, etc., you
know, set it up so that these are services that are insured on the server, so that for this video,
I hope they understood this history.
Just, uh, we need to notice this.
There is a invoice operating system which has some limitations and overcoming that invoice operating
system.
There is extra fire under it.
And then it has been very, uh, it also has some limitations, uh, like that, uh, slow progression
and also the a model then and what they came into, uh, came into the way and this ended up has been,
uh, implemented, as it were.
And then they had to mix these two into a single whole system.
