We live in the society exquisitely reliable on science and technology, where hardly anyone knows about "science and technology". The society today is mostly dependent on or prefers the internet for most of the works, may it be sending the birthday wishes, morning messages, invitations, important work files and many more. Nearly, everything is being done on the internet. Wi-Fi or mobile data consumption has increased a lot in recent years for the various works.

What is Wi-Fi? Wi-Fi is a technology for wireless local area network with devices based on the IEEE 802.11 standards. It uses the radio waves which can prove harmful to us in some cases. Even it posses high speed and secure connection as compared to mobile data, it cannot be trusted anymore because of its inability to stop the hackers from hacking the passwords and desecrate it.




To overcome this defect, Li-Fi technology was introduced. Li-Fi is a technology for wireless communication between devices using LIGHT to transmit data. It was first introduced by Harald Haas at 2011 TED Global talk in Edinburgh.

Li-Fi is a visible light communications system that is capable of transmitting data at high speeds over the visible light spectrum, ultraviolet and infrared radiation.
Like you connect the electronics device to the Wi-Fi modem, the device will itself connect itself to the internet when the wavelength of the receiver device match the transmitter device.


Just imagine a person standing under a light source, doing some work and experiencing great internet speed. Therefore elucidating the impression that workload can be handled with more efficiency. The files can be downloaded and uploaded within the fraction of seconds. Most of the effects and drawbacks of Wi-Fi can be resolved by the Li-Fi and the secure connection can be maintained. The ill effects of radio waves can be minimized.


One of my friends made a project on Li-Fi and successfully sent some random data. He even made some advancements so as to make it more secure thereby making a strong connection before the electronic device and having the safer surfing. The technology was a new exposure to us from the knowledge point of view and gave us ideas to create further advancement in accessing the secure internet and creating something that can prove a milestone for mankind. Every once in a while, a new technology, an old problem, and a big idea turn into an innovation.

Li-Fi requires three basic hardware devices to function. These include:
(i) an LED lighting system(Smart lighting system)
(ii) a router (which will be installed along with the lighting system)
(iii) a receiver equipped with decoder (in order to decrypt the light signal) which would be connected to the devices in the coming years.

The difference between Wi-Fi and Li-Fi is as mentioned:

Wi-Fi will be replaced later by Li-Fi just because the only constant in the technology industry is change and the change that is economical, efficient and profitable will sustain for the longest time.

Li-Fi has not been introduced in India because of its cost and maintaining it to keep in working condition. Once the cost becomes effective, becomes relevant enough to use easily and proves great surfing speed, people will fall for it just like they did for Reliance Jio.
Edward Teller once said" The science of today is the technology of tomorrow", but lesser is known that technology of today is the history of tomorrow.

19. Impact of COVID-19 on Technology and Cyber Security.

The world is experiencing the economic breakdown and is trying to cope up with basic amenities required for the people to survive. The COVID-19 has even challenged the economy and is affecting all the sectors. Lockdown has proved to be a solution to stop the virus transmission but is affecting the industry. But what are its impacts on technology?  The effects of COVID-19 are having a significant impact on the technology sector, affecting raw materials supply, disrupting the electronics value chain, and causing an inflationary risk on products. More positively, the disruption has caused an acceleration of remote working, and a rapid focus on evaluating and de-risking the end-to-end value chain. In addition, potential carbon emission reductions could result in renewed focus on sustainability practices. This article considers the shifting landscape across a number of areas. The main impact will be on the cybersecurity and even on supply chain. As due to this pandemic s...

8- Invisible Technology

Have you ever seen any videos on YouTube or any other source that have shown a newly under construction technology regarding use of motion sensor to replace the weighted product into the negligible one and to make the working easier without even carrying it around with us? Read down for the same. A touchscreen is an input and output device normally layered on the top of an electronic visual display of an information processing system. A user can give input or control the information processing system through simple or multi-touch gestures by touching the screen with a special stylus or one or more fingers. The motion sensor accepts the input from the motions or the movements done by the user and performs the tasks assigned to it. The smart phones today use the touchscreen and performs various tasks. Have you ever seen the battery performance on the smart phones? It will surely show you that display consumes more energy. Brightness do affects the battery life but not as the excess u...

15- 3D printer

We are all familiar with the 2D printer i.e the black and white or colour printer. The photocopy of any document is printed with the printer as per the input image that was given to it. The later world expected the things to be experienced in the actual dimensional view and this led to the invention of the 3D printer. Now, what actually is a 3D printer? Making the desired objects of any dimensions as per the actual image that was given to the input is called as the 3D printer. The image sends the information like the height, width, depth, etc to the printer through the sensors or even manual inputs can be given. The obtained information is then processed, brought together to make a digital image and hence, the printing starts. The material used here varies as per the requirements. Some materials such as liquid molecules or powder grains being fused together and the desired shape are given. The printed objects are then made to cool and acquire the firm shape. The resulting object ...
