Li - Fi Technology



Here is a masterpiece. You might have heard about the term Wi fi and its usage. But have you heard about Li-fi.?? Here is a small intro to that technology.




Li-Fi :


·       Li Fi is nothing but the Light fidelity communication systems.

·       It is the fastest and cheapest wireless communication systems and is the optical version of the Wifi.

·       The term was first used by Harald Haas in TED Global talk.
 
·       The technology works by adapting LEDs to send digital information, invisible to the naked eye.


·       A light sensor on a device picks up the digital information sent by the LED, which enables it to be processed by a computer.


·       It is similar to the Wifi except that it uses Light waves instead of Radio waves.


·       Wifi is great for general wireless coverage while Lifi is ideal for high density coverage in a confined region.


·       It is believed that the technology can yield a speed more than 10 Gbps, allowing a HD film to be downloaded within 30 seconds.


·       Its disadvantage is that the light waves cannot penetrate walls.

·       In 2012, this technology was demonstrated and it was detectable upto a distance of 10 meter.

·       Every light source in homes and offices could potentially be a “Li-Fi” within 20 years. 

 
·       When this technology becomes feasible like the Wifi, then our life will be awesome on earth.    



"This is the technology that could start to touch every aspect of human life within a decade”

Facebook - An addiction...!!


I don’t need to tell anyone about how to use facebook or what is facebook. I know, you are well aware the term and its usage. But here are just the unheard facts of facebook. Have a look at it.




  • Facebook is the world's largest social network, with more than 900 million users.

  • It was founded by Mark Zuckerberg along with his fellows Harvard university students Eduardo Saverin, Andrew McCollum, Dustin Moskovitz, Chris Hughes in Feb, 2004.

  • The site was first limited only to the Harvard university students. As it was a huge success, the site was expanded to the nearby colleges and then gradually to various other colleges and eventually to anyone aged 13 and over.

  • Facebook now allows any users who are above 13 years to be a registered user.

  • According to a May 2011 Consumer reports survey, there are 7.5 million children under 13 with accounts and 5 million under 10, violating the site's terms of service.


  • It is a multilingual networking site with more than 70 languages.

  • The Facebook font is a custom font created  by a font designer named Joe Kral, the closest font is probably Klavika Bold which is a commercial font.

  • The font used in the body text of the Facebook is Lucida Sans and Lucida Grande.

  • A January 2009 complete.com ranked Facebook as the most used social networking service.


  • It is evident that even children are addicted to Fb now.

  • The name stems from the colloquial name of the book given to the students at the start of the academic year in some universities in US to help students to get to know of each other.


  • The Predecessor to Fb was FACEMASH. It was a comparing site, asking users to select the picture which is hotter between the two branded as “HOT OR NOT”.


  • Facebook has met with controversies also . It has been blocked intermittently in several countries including the People's Republic of China, Iran, Uzbekistan, Pakistan and Bangladesh on different bases.
