Time For Gbps Faster Communication - LiFi

Time For Gbps Faster Communication - LiFi

  • Li-Fi is a label for wireless-communication systems using light as a carrier instead of traditional radio frequencies, as in Wi-Fi.
  • Guys time to adopt a new technology and transfer your data at GB per second and leaving the speed of Kbps & Mbps transfers of data.




  •  Li-Fi should not be confused with the more general term Visible Light Communications (VLC), which is the use of the visible light portion of the electromagnetic spectrum to transmit information. The term Li-Fi was coined by Professor Harald Haas from the University of Edinburgh in the UK and pureVLC™’s CSO, and refers to a type of VLC technology that delivers a networked, mobile, high-speed communication solution in a similar manner as Wi-Fi. Therefore, the fundamental pre-requisite for Li-Fi is a bi-directional link over the same medium. The term was first used in this context by Harald Haas in his 2011 TED Global talk on visible light communication.




  •  In October 2011, a number of companies and industry groups formed the Li-Fi Consortium, to promote high-speed optical wireless systems and to overcome the limited amount of radio-based wireless spectrum available by exploiting a completely different part of the electromagnetic spectrum. The consortium believes it is possible to achieve more than 10 Gbit/s, theoretically allowing a high-definition film to be downloaded in 30 seconds. In fact, Dr Gordon Povey provides a top level overview of VLC development until the end of 2011.


  •  A number of companies offer uni-directional VLC products, however, the only known bi-directional system on offer is by pureVLC™. PureVLC™ is an original equipment manufacturer (OEM) firm set up to commercialize Li-Fi, by bring out Li-Fi products for integration with existing LED-lighting systems.
  •  Li-Fi is a new paradigm for optical wireless technology to provide unprecedented connectivity within a localized data-centric environment. The increasing demand for higher bandwidths, faster and more secure data transmission as well as environmental and undoubtedly human friendly technology heralds the start of a major shift in wireless technology, a shift from RF to optical technologies.

Android - History Of A Versatile Platform (Updated AUG-2020)

Image
 Introduction - ANDROID - Android Means A Robot With A Human Appearance. Google's Android division certainly has a sense of humor as it named all their version codenames after desserts (just as Intel name all its CPUs after rivers). To celebrate new version release of Android, a giant mock-up of the dessert that matches the codename is usually delivered to the Google Campus and put on display.  Version 1.0 : No Codename Version 1.1 : No Codename Version 1.5 : Cupcake   Version 1.6 : Donut Version 2.0-2.1 : Eclair Version 2.2-2.2.3 : Froyo Version 2.3-2.3.7 : Gingerbread Version 3.0-3.2.6 : Honeycomb Version 4.0-4.0.4 : Ice Cream Sandwich Version 4.1-4.3.1 : Jelly Bean Version 4.4-4.4.4 : Kitkat Version 5.0-5.1.1 : Lollipop Version 6.0-6.0.1 : Marshmallow Version 7.0, 7.1.0-7.12 : Nougat Version 8.0 & 8.1 : Oreo Version 9.0 : Pie Version 10 : Android 10 / Android Q

History From "OS X" To "iOS7" - Apple Inc.

Introduction - Apple marketing literature simply stated that their iPhone runs a version of "OS X". When introduced, it was named iPhone OS . It was renamed iOS on June 7, 2010, as iPhone was no longer the only device to run iOS. Apple licensed the "iOS" trademark from Cisco. Apple Inc. provides updates to the iOS operating system for the iPhone, iPad, and iPod Touch through iTunes, and since iOS 5.0, also through over-the-air software updates. iPhone OS 1.x First iteration of Apple's touch-centric mobile operating system. No official name given on its initial release; Apple marketing literature simply stating the iPhone runs a version of Apple's desktop operating system, OS X. On March 6, 2008, with the release of the iPhone software development kit (iPhone SDK), Apple named it iPhone OS . iPhone OS 2.x 2.0, the second major release of the iOS, became available with the release of the iPhone 3G. Devices running 1.x are upgradable to
