00:00:00,240 --> 00:00:06,620
Hi, everyone, welcome back to this lecture and this lecture, we are going to learn about Wi-Fi.

2
00:00:07,170 --> 00:00:12,660
So before getting started into spectacles, I would like you to tell you that the upcoming two or three

3
00:00:12,660 --> 00:00:19,310
videos is going to be very important for the deep understanding of the Wi-Fi and its security mechanism.

4
00:00:20,040 --> 00:00:25,590
So this video will take you through the beginning of Wi-Fi, how wireless interfaces works, how Wi-Fi

5
00:00:25,590 --> 00:00:32,190
is different and better from Bluetooth, and you will be learning very similarity between all of these

6
00:00:32,190 --> 00:00:32,900
devices.

7
00:00:33,540 --> 00:00:40,920
So I would like you to tell you that it is very important because the build of use of a strong foundation

8
00:00:40,920 --> 00:00:48,120
in wireless networking razu capabilities and will be helpful in your life, especially for security

9
00:00:48,120 --> 00:00:48,900
related carrier.

10
00:00:49,410 --> 00:00:53,280
So now let's start and see what is Wi-Fi and how does it work?

11
00:00:53,500 --> 00:00:53,840
OK.

12
00:00:56,160 --> 00:01:03,570
So Viva is the name of proper wireless networking technology that uses radio waves to propagate, to

13
00:01:03,600 --> 00:01:11,320
air for providing high speed Internet and network connections, reducing users of wires effectively.

14
00:01:11,940 --> 00:01:13,740
Then what is the need of Wi-Fi?

15
00:01:13,830 --> 00:01:19,300
It is very important to understand the world has always been moving towards the better.

16
00:01:19,530 --> 00:01:26,100
And according to the statistics, it is clear that in the next five years a large population will be

17
00:01:26,100 --> 00:01:33,060
using violence devices for the purpose, like storing data is streaming music, accessing high speed

18
00:01:33,060 --> 00:01:34,820
Internet and many more things.

19
00:01:35,730 --> 00:01:43,050
So wireless technology not only serves the element used to manufacture the fires, but also provides

20
00:01:43,650 --> 00:01:46,950
very much less the installation cost of the devices.

21
00:01:47,670 --> 00:01:55,260
Since there is no wire for them, we can see predebate installation, but just some information to be

22
00:01:55,260 --> 00:01:58,820
registered, which is perhaps a matter of the few minutes.

23
00:01:59,430 --> 00:02:06,220
So as we see today, wireless devices have become an essential part of our life.

24
00:02:06,780 --> 00:02:11,760
So over time it is going to expand to as much people as it can.

25
00:02:12,640 --> 00:02:19,090
Has more wireless devices, more the vulnerabilities and more the need to Wi-Fi security experts will

26
00:02:19,090 --> 00:02:19,510
be there.

27
00:02:19,900 --> 00:02:25,410
That is why it is very important to understand how Wi-Fi works, what is the need of Wi-Fi?

28
00:02:25,750 --> 00:02:30,730
And later on, we are going to see some security mechanism that Wi-Fi uses.
