Hi, everyone, welcome back to this lecture and this lecture, we are going to learn about Wi-Fi.
So before getting started into spectacles, I would like you to tell you that the upcoming two or three
videos is going to be very important for the deep understanding of the Wi-Fi and its security mechanism.
So this video will take you through the beginning of Wi-Fi, how wireless interfaces works, how Wi-Fi
is different and better from Bluetooth, and you will be learning very similarity between all of these
devices.
So I would like you to tell you that it is very important because the build of use of a strong foundation
in wireless networking razu capabilities and will be helpful in your life, especially for security
related carrier.
So now let's start and see what is Wi-Fi and how does it work?
OK.
So Viva is the name of proper wireless networking technology that uses radio waves to propagate, to
air for providing high speed Internet and network connections, reducing users of wires effectively.
Then what is the need of Wi-Fi?
It is very important to understand the world has always been moving towards the better.
And according to the statistics, it is clear that in the next five years a large population will be
using violence devices for the purpose, like storing data is streaming music, accessing high speed
Internet and many more things.
So wireless technology not only serves the element used to manufacture the fires, but also provides
very much less the installation cost of the devices.
Since there is no wire for them, we can see predebate installation, but just some information to be
registered, which is perhaps a matter of the few minutes.
So as we see today, wireless devices have become an essential part of our life.
So over time it is going to expand to as much people as it can.
Has more wireless devices, more the vulnerabilities and more the need to Wi-Fi security experts will
be there.
That is why it is very important to understand how Wi-Fi works, what is the need of Wi-Fi?
And later on, we are going to see some security mechanism that Wi-Fi uses.
