Li-Fi technology is a ground-breaking light-based communication technology, which makes use of light waves instead of radio technology to deliver data.

Technology:-

* Li-fi uses Visible Light Spectrum for data transmission.

* Wi-Fi uses the traditional RF spectrum.

Bandwidth:-

* RF spectrum is overcrowded, with Wi-Fi, Bluetooth, Cellular data etc. all sharing the same band.

Visible Light Spectrum is 10,000 times the Rf spectrum. Thus a lot of free band space for new technologies

WHAT IS XAMARIN?

Xamarin is a development platform that allows us to code native, cross-platform iOS, Android, and Windows Phone apps in C#.

XAMARIN NOW FREE IN VISUAL STUDIO

 Xamarin’s cross-platform tools available in Visual Studio, from Community up through Enterprise at no additional cost, to get started with Xamarin on Visual Studio 2015 or Visual Studio 2013, download the Xamarin installer for Windows. If you are installing Visual Studio 2015 for the first time, downloading Visual Studio 2015 Update 2 will also include Xamarin tools. Similarly, Visual Studio “15” Preview installer will automatically install Xamarin Tools.

Here is a little list of things that, in my experience, contribute to make Objective-C a powerful and fun programming language.

Classes are objects

Each class is an instance of a meta-class automatically created and managed by the run-time. We can define class methods, pass classes as arguments, put them in collections and so on. To create an object, we just send a message to the class we want to instantiate. No need to reinvent a "factory" system. No need for a specific constructor mechanism at the language level. This helps keeping the language simple and powerful.

And, by the way, meta-classes are objects too!

The next step after planning is execution. Before starting on this phase, most of the Mobile App Development companies are faced with having to answer this question more than once – Do I build a Hybrid Mobile App or Native Mobile App?

Native applications

Native applications are downloaded through application stores (App Store, Google Play or its affiliates, Windows phone store etc.) and installed in the smartphone software. An essential difference is that native applications are developed solely for a certain platform (for example, iOS, Android or Windows Phone) and require from a mobile software developer particular skills and abilities to work in a certain environment (xCode for iPhone, eclipse for Android). In addition, only “native” programming languages can be applied for creating such applications. The process is, of course, more labour-consuming.

                  Smartphones and tablets are the inseparable part of our everyday life, therefore, different companies are involved in mobile application development. However that kind of activity needs to be clearly defined in mobile application development check list to achieve the main goal – development of a popular application. So what questions should be answered? See the full IOS and Android application development check list.

Web hosting is a service that allows organizations and individuals to post a website or web page on to the Internet. A web host, or web hosting service provider, is a business that provides the technologies and services needed for the website or webpage to be viewed in the Internet. Websites are hosted, or stored, on special computers called servers.
