1
00:00:02,090 --> 00:00:03,050
Well, hello again.

2
00:00:03,680 --> 00:00:14,210
And now we have the ozone and dissipate IP models, and here gives us the explanation that I told you

3
00:00:14,210 --> 00:00:21,110
before to remember in the layer that multiplexing, what is the multiplexing?

4
00:00:21,290 --> 00:00:30,560
Is it sending different communication on the same circuit and also increase the reliability of communication

5
00:00:30,570 --> 00:00:31,190
segments?

6
00:00:31,250 --> 00:00:38,570
Can we use different circuits and only missing segments in case of their loss should be transmitted

7
00:00:38,600 --> 00:00:39,230
again?

8
00:00:41,230 --> 00:00:42,060
What are busy?

9
00:00:43,520 --> 00:00:51,140
So basically, they are talking about this, which what is this which are?

10
00:00:53,240 --> 00:01:00,500
Oh, I'm going to what is this, which is which is when we have a line and what is line?

11
00:01:00,530 --> 00:01:02,000
It is a local area network.

12
00:01:03,950 --> 00:01:08,030
And here is this, which this is the logo of the switch.

13
00:01:09,350 --> 00:01:10,790
And this is the server.

14
00:01:10,860 --> 00:01:14,090
Here are the computers and an IP phone.

15
00:01:15,630 --> 00:01:16,770
So when we have this which.

16
00:01:17,790 --> 00:01:23,700
This, which is a multiple ports with one with one.

17
00:01:24,450 --> 00:01:26,010
And remember this very.

18
00:01:27,000 --> 00:01:28,800
And remember it very carefully.

19
00:01:29,370 --> 00:01:35,250
We have one port as an entrance and 24 at least ports as exits.

20
00:01:35,730 --> 00:01:38,790
So we take the information from that one port.

21
00:01:39,210 --> 00:01:40,370
It could be a rotor.

22
00:01:40,380 --> 00:01:42,690
And in this case, we have a server webserver.

23
00:01:43,680 --> 00:01:54,690
And we should we should multiply, transfer the messages and every message is different from the other

24
00:01:54,690 --> 00:01:59,550
end or it can be sent to the users, which are these computers?

25
00:02:01,160 --> 00:02:03,890
This is what multiplexing is about.

26
00:02:05,020 --> 00:02:08,590
And they are present in the different communication on the same circuit.

27
00:02:08,890 --> 00:02:10,030
This is what we said.

28
00:02:10,360 --> 00:02:14,800
It's a grisly ability of communications on the missing segment.

29
00:02:15,340 --> 00:02:20,170
They can be transmitted again, nowhere the size of the network.

30
00:02:21,420 --> 00:02:22,500
What can we say?

31
00:02:23,890 --> 00:02:27,340
About or have you ever heard about one or one?

32
00:02:28,150 --> 00:02:34,180
Here we have the line, we already explained that it is a local area network when we don't use our outer.

33
00:02:35,200 --> 00:02:42,250
So this is a did I'm going to get I'm going to give you a tip so you can be it more smart how to deal

34
00:02:42,340 --> 00:02:50,110
with with such things, it takes some experience, but this is why we are here, why we are here.

35
00:02:50,440 --> 00:02:54,230
So when you see a A.

36
00:02:56,890 --> 00:02:59,800
A network without a realtor.

37
00:03:00,860 --> 00:03:07,750
Different, there is a lot is a local area network, a local network means a local network typically

38
00:03:07,750 --> 00:03:10,100
spend single geographic area.

39
00:03:10,120 --> 00:03:10,990
Exactly, yes.

40
00:03:11,410 --> 00:03:20,080
And provide services and applications to the people within a commune organizational structure, such

41
00:03:20,080 --> 00:03:24,450
as businesses, Gompers regions that will basically that.

42
00:03:24,460 --> 00:03:26,590
Are you saying when we have a network?

43
00:03:27,900 --> 00:03:29,430
That you a kill.

44
00:03:30,180 --> 00:03:39,330
We have a network that we connect with each other with a cable, and that cable is RJ 45 or RJ 11,

45
00:03:39,780 --> 00:03:41,940
or it can be that.

46
00:03:42,690 --> 00:03:44,680
I don't know any cable.

47
00:03:46,000 --> 00:03:47,440
And what is why?

48
00:03:47,950 --> 00:03:50,860
What is what it is a wide area network.

49
00:03:53,180 --> 00:04:03,230
Wide area network here, we can use it, Rogers, when we see there's Rogers between two two lines and

50
00:04:03,500 --> 00:04:07,190
two local area networks, we use that draw outdoors.

51
00:04:07,190 --> 00:04:11,030
That means you are connected, different, different.

52
00:04:12,080 --> 00:04:16,340
They can be the same, the same network, but they are in different location.

53
00:04:17,120 --> 00:04:21,560
That means you are going to use a wireless connection.

54
00:04:24,400 --> 00:04:30,310
I'm sorry there is a mistake here, one wireless area network, not wide area network.

55
00:04:31,150 --> 00:04:32,680
I'm going to correct this.

56
00:04:34,510 --> 00:04:35,860
Wireless.

57
00:04:44,360 --> 00:04:44,790
Worms.

58
00:04:45,390 --> 00:04:47,790
Area Network.

59
00:04:54,770 --> 00:05:04,890
We should remember here we have a wider area and it's not wide, and it's it means we're a company or

60
00:05:04,900 --> 00:05:05,180
organs.

61
00:05:05,210 --> 00:05:11,460
That organization has location separated by a large geographical distance.

62
00:05:11,480 --> 00:05:18,260
As I explained before, it may be necessary to use telecommunications services or telecommunications

63
00:05:18,260 --> 00:05:26,060
service providers, you know, for telecommunication to interconnect a local area network in different

64
00:05:26,060 --> 00:05:26,560
locations.

65
00:05:26,570 --> 00:05:34,280
That means are going to use a a provider, a telecommunications service provider to give us a private

66
00:05:34,700 --> 00:05:41,870
wireless IP address or a wireless network so we can communicate with each other in a secure way.

67
00:05:42,810 --> 00:05:50,270
We are going to what we are doing this while we are doing all of this, the complications just.

68
00:05:51,710 --> 00:05:56,780
For a secure communication or for a secure transfer.

69
00:05:58,380 --> 00:06:01,170
And now we are going to see you next.
