What is Li-Fi Technology ?

 Li-Fi full name is Light-Fidelity. 

This technology was first discovered by Professor Harald Haas. In 2011, he first published the Li-Fi in front of the people. And he showed how you can communicate with the help of lights. Anyway then he continued to do more detailed research on this technology and he tested this technology about 6 months ago. And test results showed that  Li-Fi was faster than Wi-Fi



In fact, this technology is VLC or Visible Light Communication works on ideas. Now what is this VLC, see if you give constant input power to an LED bulb, you will also see its output constant. If you change some of the input power, you will also see a change in the output. The faster you change the input, the faster you see the output change. And with this idea you can create a kind of communication system.

You still do not fully understand the matter? Well let me give you more examples. Think of the TV remote this time. In fact, there is an infrared bulb in front of the TV remote. And when you press a certain button of the remote, the light of the specified position on the bulb goes into the water. This time the sensor on your TV realizes that attitude and completes its work. Suppose the remote bulb beeps twice to change the TV channel, then the bulb will beep twice when you press the remote to change the channel. And the sensors on the TV will pick it up, your TV already has a program that needs to change the channel after receiving a beep twice. Come on, this time it's as clear as water. 

The main aims of Li-Fi technology is a lot like this. But like a TV remote, Li-Fi has many bulbs, not just one, so you can exchange data much faster and many users can use it at the same time. In fact, VLC is the common medium for managing this technology. But this technology is able to give you something more. It will not happen that you will move away from the light of the LED bulb and your internet will be turned off. 

This technology will automatically connect to you whenever you move from one bulb source to another. The common bulbs we use in the office or home can only be replaced by LED bulbs and a type of driver can be used to use this technology.


With the light coming from the roof of the house, you can also use the internet, but also much faster.

What should the processor look at?

Clock speed means how fast your computer can work. That's what this signal means. The speed of the processor is known through this clock speed, how fast the calculation can be done. 2. Number of Cores: The more cores the processor has, the faster the processor can work. If I give an example to explain the matter, I hope you can understand it very easily. Suppose if a person had many hands, then he could do many things at the same time. That is, if we go to the market and buy a smartphone, then we will see what the configurations of the phone are. If we look closely at the configuration of the smartphone, we will see that Dual Core Processor, Quad Core Processor, Octa core processor, Hexa core processor, Deca core processor.
