1
00:00:00,570 --> 00:00:05,880
Now, let's talk about the history of the actual tree from Wales or ordinator.

2
00:00:06,210 --> 00:00:10,770
So first those introduced this Andy Serwer, uh, new technology.

3
00:00:11,010 --> 00:00:17,850
And with this, they have to do a separate operating system for Sarasate, for managing services, as

4
00:00:17,850 --> 00:00:18,180
you can see.

5
00:00:18,210 --> 00:00:21,940
This is called and Hoya's Operating System Network Operating System.

6
00:00:21,990 --> 00:00:28,580
So this is installed on the Saraa computer, which has very powerful configuration.

7
00:00:28,890 --> 00:00:36,870
And then in this server that we use to carry the information about the cranes and also cranes, request

8
00:00:36,870 --> 00:00:41,960
the queries about some information and the server will do so.

9
00:00:42,600 --> 00:00:49,390
It is introduced in the 1990s, I don't know particularly here, but just here is not a model.

10
00:00:49,680 --> 00:00:56,880
So then what the hell is this empty invoice operating system on Windows Server then?

11
00:00:57,360 --> 00:01:02,450
This, uh, invoice operating system has, uh, uh, limitations.

12
00:01:02,910 --> 00:01:07,660
So that is, uh, it can only generate up to 40000 objects.

13
00:01:07,670 --> 00:01:15,750
So whether if you want to create users or computers, printers, groups, etc., all you can do is up

14
00:01:15,750 --> 00:01:20,340
to only 40000 objects on the water account you can create is part of the.

15
00:01:22,260 --> 00:01:29,130
If your organization is small, then it's OK, if it doesn't is fine, but if any big, upper, big

16
00:01:29,160 --> 00:01:35,250
organization wants to use this and then they have so much limitations because of 40000 objects may not

17
00:01:35,250 --> 00:01:36,190
be sufficient.

18
00:01:36,660 --> 00:01:44,160
So that's why what they have done is they have removed this invoice and they have created the extra

19
00:01:44,180 --> 00:01:45,760
finder directory services.

20
00:01:46,670 --> 00:01:55,940
So this supports more than part objects, and you can see here, this is the diagram, sorry for not

21
00:01:55,940 --> 00:01:57,380
making PowerPoint presentation.

22
00:01:57,530 --> 00:02:01,390
So this is the kind and connected to these servers, to servers.

23
00:02:01,400 --> 00:02:09,260
We have extra funded servers and this client will ask for information using this directory access protocol,

24
00:02:09,590 --> 00:02:12,220
and the server uses a directory service protocol.

25
00:02:12,230 --> 00:02:18,260
So using the staff grant will connect to the server and coding for any information he wants.

26
00:02:19,470 --> 00:02:26,910
So this is a very good one, actually founded it has overcome the limitations of this and its operating

27
00:02:26,910 --> 00:02:27,370
system.

28
00:02:27,390 --> 00:02:30,090
So the directory service is excellent.

29
00:02:30,450 --> 00:02:36,030
So this expert finder uses all you say more as a reference.

30
00:02:36,060 --> 00:02:39,480
So it's a model it uses for interaction and communication.

31
00:02:40,390 --> 00:02:50,590
Then in the early 2000 or 1995, it was then this TCP IP model has been implemented in order to assist

32
00:02:51,040 --> 00:02:52,140
all over the network.

33
00:02:52,480 --> 00:02:59,620
So this became very tough, very tough to handle, and also better application or database replication

34
00:02:59,620 --> 00:03:00,830
from one to another.

35
00:03:00,830 --> 00:03:05,800
Server is very low across this extraordinary directory services.

36
00:03:06,340 --> 00:03:11,630
So if the server wanted to send a database to the server and want to replicate.

37
00:03:11,950 --> 00:03:14,560
So this takes more time.

38
00:03:14,590 --> 00:03:21,830
So whenever you have so much of an application going on, then this is not considered as a good one.

39
00:03:23,080 --> 00:03:30,940
So that's why they have implemented this and ended up stands for Directory Access Protocol.

40
00:03:31,300 --> 00:03:36,940
So this is like Middlesworth between the client and the Explorer Finder, uh, server.

41
00:03:37,330 --> 00:03:42,730
As you can see, the first client since using FDCPA because the computer using the user by the client

42
00:03:43,030 --> 00:03:44,930
has been implemented that E.S.P.

43
00:03:45,070 --> 00:03:52,850
So this request will be converted into the OSA model using this adultry access protocol, because all

44
00:03:52,850 --> 00:04:00,420
of the computers and at the 2000 using this model so that the requested we can return to the Western

45
00:04:00,430 --> 00:04:05,920
model because this already this layers will be understood by the actual vendor.

46
00:04:05,930 --> 00:04:10,900
So that's where this ended up are they want to process have been installed on this, uh, middleware

47
00:04:11,050 --> 00:04:11,550
server.

48
00:04:11,860 --> 00:04:15,640
So to convert this VIP package, it's always separate.

49
00:04:17,260 --> 00:04:25,390
So now the sex offenders understand the request and processes that request and send the response, so

50
00:04:26,350 --> 00:04:27,350
this was verified.

51
00:04:27,520 --> 00:04:34,770
So they have got much idea that to mix these two services.

52
00:04:34,780 --> 00:04:42,550
So be sure we can remove this material and implement this in the server, then this accurately came

53
00:04:42,550 --> 00:04:44,770
into place actually is like a phone book.

54
00:04:44,800 --> 00:04:49,770
It is not any service to directory users and services.

55
00:04:50,050 --> 00:04:53,490
So there is a recent update, uh, version three.

56
00:04:54,070 --> 00:05:01,570
So this portion will be installed along with this actor to try to retrieve the phone.

57
00:05:01,780 --> 00:05:07,410
It contains every other every object information and data.

58
00:05:08,590 --> 00:05:21,490
And this that client access to this data using this services and also this to the tree will be will

59
00:05:23,370 --> 00:05:30,170
I mean, they will ask for any other information on the client, the printers, computers, etc., you

60
00:05:30,190 --> 00:05:38,200
know, set it up so that these are services that are insured on the server, so that for this video,

61
00:05:38,430 --> 00:05:40,290
I hope they understood this history.

62
00:05:40,630 --> 00:05:43,390
Just, uh, we need to notice this.

63
00:05:43,540 --> 00:05:48,660
There is a invoice operating system which has some limitations and overcoming that invoice operating

64
00:05:48,670 --> 00:05:48,910
system.

65
00:05:49,000 --> 00:05:50,340
There is extra fire under it.

66
00:05:50,770 --> 00:06:00,610
And then it has been very, uh, it also has some limitations, uh, like that, uh, slow progression

67
00:06:00,610 --> 00:06:11,080
and also the a model then and what they came into, uh, came into the way and this ended up has been,

68
00:06:11,170 --> 00:06:12,880
uh, implemented, as it were.

69
00:06:12,880 --> 00:06:17,020
And then they had to mix these two into a single whole system.
