00:00:02,120 --> 00:00:02,840
Hello again.

2
00:00:04,110 --> 00:00:11,880
Well, as we knew, the difference between local area network and wireless area network and are going

3
00:00:11,880 --> 00:00:15,840
to address them as LAN or Wan lent when.

4
00:00:18,150 --> 00:00:25,280
And now we are going to see the hard work composed of a network, what is what, what can we touch the

5
00:00:25,470 --> 00:00:26,810
stuff that we can touch?

6
00:00:27,240 --> 00:00:32,220
Now we have and devices and also hosts what are our hosts?

7
00:00:32,670 --> 00:00:39,300
They are a form of interface between the human network and the underlying communication network is through

8
00:00:39,300 --> 00:00:40,610
a computer network printer.

9
00:00:40,770 --> 00:00:45,240
Epiphone and Surveyor surveys a surveillance camera.

10
00:00:45,600 --> 00:00:54,550
By the way, my small little, not me, my end of the year project when I was in school, it was about

11
00:00:54,630 --> 00:00:58,680
the device before it was both connected to.

12
00:00:59,660 --> 00:01:01,460
Two different machines.

13
00:01:02,750 --> 00:01:06,620
One used Linux and the other is Windows seven.

14
00:01:06,800 --> 00:01:07,520
Back in the day.

15
00:01:09,410 --> 00:01:20,150
And I had to install the secured network and also a VIP thorn in the Linux was going to be the the main,

16
00:01:20,150 --> 00:01:25,790
uh, the main person to go all the client, which was the windows.

17
00:01:26,000 --> 00:01:32,630
And you can you can see I have the detailed information about how to make a VIP phone between Linux

18
00:01:32,630 --> 00:01:37,330
and and a Windows in my neck that date.

19
00:01:37,520 --> 00:01:44,360
I'm going to put it on description and now we have the intermediate devices.

20
00:01:46,170 --> 00:01:53,670
What are the intermediate devices such as hops, switches, wireless access points, wireless routers,

21
00:01:53,670 --> 00:01:55,380
browsers, firewalls?

22
00:01:56,370 --> 00:01:58,740
These are the devices.

23
00:01:59,900 --> 00:02:00,800
That conduct.

24
00:02:02,220 --> 00:02:03,540
The network with each other.

25
00:02:04,620 --> 00:02:12,810
That connect the main thing to the user and the main thing or the mean machine is basically the server,

26
00:02:13,470 --> 00:02:23,430
so very is is everything and you, the user, is the whether it is the client or the, I don't know,

27
00:02:23,430 --> 00:02:31,350
the agent, the person with the computer and between the server and the computer we call them, we call

28
00:02:31,470 --> 00:02:38,100
all the things that in between the intermediate intermediate devices.

29
00:02:39,930 --> 00:02:45,540
And then we have the network supports it as the metal wires, optical fibers, wireless transmissions,

30
00:02:46,650 --> 00:02:51,590
the distance over which media can probably properly carry the signal.

31
00:02:51,610 --> 00:02:55,770
The hero are going to use a protocol, which is which is called the.

32
00:02:57,530 --> 00:03:04,080
You are going to use a protocol which is called a.

33
00:03:07,510 --> 00:03:09,280
Eli, are big.

34
00:03:09,970 --> 00:03:10,690
And here.

35
00:03:12,580 --> 00:03:22,390
The amount of data transmissions are going to use a protocol that is called the Oh, let's b is I'm

36
00:03:22,420 --> 00:03:23,260
giving you this.

37
00:03:24,530 --> 00:03:34,100
Do stuff so you can know about because it is in the invented and advanced part of learning, networking

38
00:03:34,140 --> 00:03:34,970
and physical package.

39
00:03:35,030 --> 00:03:36,220
Is it because it is?

40
00:03:36,230 --> 00:03:42,690
It is something very little to your own such and such such stuff because of the media installation.

41
00:03:42,710 --> 00:03:44,600
Yes, we are going to always be here.

42
00:03:47,200 --> 00:03:52,220
I know you are going to learn divisive symbols and network supports.

43
00:03:52,240 --> 00:03:56,740
Basically, the we have them here, we have them here.

44
00:03:57,890 --> 00:04:01,460
And each I mean, the voice.

45
00:04:02,060 --> 00:04:09,560
And when you click on, I come in, give us the multiple the voices in the same.

46
00:04:10,790 --> 00:04:12,200
Type of device.

47
00:04:14,560 --> 00:04:20,350
I'm going to give you an example, such as you have the rotors, a rotor overalls.

48
00:04:20,790 --> 00:04:24,300
We are going to use very, very much in our cars.

49
00:04:24,300 --> 00:04:25,700
We have this simple Wrangler.

50
00:04:27,540 --> 00:04:29,310
I'm so sorry about this.

51
00:04:31,460 --> 00:04:35,930
And then we are going to use the wireless router.

52
00:04:37,790 --> 00:04:39,920
And we are going to use the.

53
00:04:43,150 --> 00:04:45,430
Basically, this this is everything.

54
00:04:45,530 --> 00:04:47,850
I'll go into the water and the water shelter.

55
00:04:48,520 --> 00:04:49,260
I am going.

56
00:04:49,270 --> 00:04:52,210
I am going to put the project where the ground terminal.

57
00:04:54,110 --> 00:04:57,530
Maybe in the end, because it is very high experience level.

58
00:04:58,550 --> 00:05:01,550
And we are going to see the other side of it.

59
00:05:02,090 --> 00:05:05,210
We have heard the hubbub this is we're having to switch.

60
00:05:05,360 --> 00:05:06,940
This is the icon of the switch.

61
00:05:07,680 --> 00:05:15,340
We've talked before then we have here at the hub, this stupid device, as we we mentioned before,

62
00:05:15,340 --> 00:05:18,500
we call it stupid or less work than we have here.

63
00:05:18,520 --> 00:05:24,530
The server IP phone, the firewall, the laptop, the computer basics.

64
00:05:24,830 --> 00:05:27,950
You have the access point, the wireless access point.

65
00:05:28,310 --> 00:05:30,530
We we have the wireless router.

66
00:05:32,000 --> 00:05:37,490
The wireless router is very interesting to learn about in Cisco Pocket router that it experienced.

67
00:05:37,700 --> 00:05:37,940
If.

68
00:05:39,410 --> 00:05:45,290
Then we have that wireless connection.

69
00:05:45,290 --> 00:05:52,070
This this is the thinking of the wireless connection between two networks and this is the the the local

70
00:05:52,220 --> 00:05:57,650
connection or the local area network connection and Cisco Bucket.

71
00:05:58,100 --> 00:06:02,240
Here we have the wireless connection.

72
00:06:04,440 --> 00:06:10,290
The difference between these two, this is for a one wireless area network, and this is going to it

73
00:06:10,290 --> 00:06:17,970
can be outside a one area network because we're going to have cases when we have network and just one

74
00:06:17,970 --> 00:06:24,570
computer with a with a with Iran, and we called it a we were not going to with anything.

75
00:06:24,570 --> 00:06:29,790
It's going to be just a computer that is, it's going to be a client by by the internet or something.

76
00:06:29,790 --> 00:06:33,480
We use this type of of connection so we can.

77
00:06:35,950 --> 00:06:38,290
We can mention it's in our pocket raised.

78
00:06:40,100 --> 00:06:44,390
Here we are going to see the Composantes, the software composantes.

79
00:06:46,090 --> 00:06:53,140
And the layered model already talked about, and there are the protocols and they are the layers.

80
00:06:54,940 --> 00:06:59,650
So what we are going to see next is the message, I'm sorry.

81
00:07:00,250 --> 00:07:04,870
Here we have the network addressing, as I told you, the thing that we call the message and we called

82
00:07:04,870 --> 00:07:07,870
specifically in networking and elections.

83
00:07:09,100 --> 00:07:16,330
Here we have it, here we have the physics part, the physical part and then the datalink, then the

84
00:07:16,330 --> 00:07:21,550
network, then the transport, then the top players, the other three layers that we talked about.

85
00:07:21,940 --> 00:07:31,390
And in every and in every part, you are going to have between eight or 16 zeros and ones and every

86
00:07:31,900 --> 00:07:36,920
eight and 16 zeros and the ones means iMessage, and we are going to see that later.
