LiFi Technology

 What is LiFi? LiFi, also known as "Light Fidelity" is a wireless optical networking technology, which uses light emitting diodes (LEDs) to transmit data. In 2011, professor Harald Haas made a LiFi demonstration at the TED (Technology, Entertainment, Design) Global Talk on Visible Light Communication (VLC).VLC involves light as medium to deliver high-speed communication in a manner similar to Wi-Fi and agrees with the IEEE standard IEEE 802.15.7. The IEEE 802.15.7 is a high-speed, bidirectional and completely organized wireless communication technology-based standard similar to Wi-Fi's IEEE 802.11. How does LiFi work? LiFi is a high speed, bidirectional, and completely organized wireless communication of data using light. LiFi comprises of several lightbulbs that structure a wireless organization. At the point when an electrical current is applied to a LED light bulb a stream of light (photons) is emitted from the bulb. LED bulbs are semiconductor gadgets, and that means

METAVERSE - THE FUTURE WORLD

What is Metaverse?

Metaverse is a wide term. It generally refers to shared virtual world environments which people can access via the internet.

The term can allude to advanced spaces which are made more exact by the utilization of virtual reality (VR) or increased reality (AR).

Some people also use the word metaverse to describe gaming universes, in which users have a person that can stroll around and cooperate with other players.

There is likewise a particular kind of metaverse which utilizes blockchain innovation. In these, clients can purchase virtual land and other computerized resources utilizing cryptocurrencies.

Many science fiction books and films are set in fully-fledged metaverses - elective computerized universes which are indistinguishable from the genuine actual world. Be that as it may, this is as yet the stuff of fiction. As of now, most virtual spaces look more like the inside of a computer game than reality.


How does the metaverse work?

In 2016, Facebook launched its first Oculus VR headset called Oculus Rift, and then Oculus Quest in 2019. Following Meta's announcement, the VP of VR/AR and incoming Meta CTO, Andrew Bosworth, declared that the Oculus brand name will be retiring for the more bound together Meta. While the headsets will remain, Facebook has effectively introduced some more VR normal other options, similar to a couple of smart glasses made in collaboration with Ray-Ban.
With respect to the metaverse itself, Zuckerberg's vision builds upon features that Facebook as of late delivered. Over the late spring, Facebook dispatched the Horizon Workrooms app—a computer generated experience remote work app for anyone with Quest 2 headsets to hold virtual meetings with their coworkers as avatars.

That is only a hint of something larger. "Horizon" is an entire social platform for the metaverse. Which began with Workrooms will soon also include Horizon Home, where users can construct their aforementioned custom home spaces, as well invite other friends over to their space as avatars. Future projects include Horizon Universes, which permits users to construct spaces past work and home. This virtual world would also expand to include things like gaming and training. Also to come? Another cutting edge VR headset called Project Cambria, which will permit avatars to keep in touch and mimic facial expressions.


How can creators use the metaverse?

The metaverse brings an entirely new definition to the concept of "creator." The present moment, being a computerized content creator means sharing visual and sound substance for users to burn-through, and making cash by partnering with brands. In the metaverse, notwithstanding, computerized creation could mean making advanced items—like clothing for symbols—to sell on what's to come "Horizon Marketplace." For instance, creators could make virtual art that users buy to display in their homes or receive monetary tips from users who simply want to view and appreciate the art.

Why is it taking off?

Fans of the metaverse consider it to be the following stage in the improvement of the web. 

At the moment, people interact with each other online by going to websites like web-based media platforms or utilizing informing applications. The possibility of the metaverse is that it will create new online spaces in which people's interactions can be more multi-dimensional, where clients can submerge themselves in computerized content rather than essentially seeing it.

Why is Zuckerberg so focused on the metaverse?

Facebook, which wouldn't remark for this story, has lost ground among more youthful clients to YouTube, TikTok and Snapchat. While Instagram stays famous with youngsters, Facebook's unique application isn't. Expanded consideration around hostile to believe issues implies Facebook probably can't buy any new contenders. Assuming it needs an application to win back youngsters, it should fabricate it itself, and Zuckerberg appears to feel a VR-focused metaverse will do this. ("We're retooling our group to make youthful grown-ups our north star," he said on last week's Money Road telephone call.) Additionally, discussing the metaverse gives an ideal interruption from an informant embarrassment burning-through a significant part of the media consideration around Facebook.
