Samsung Announced '5G' Wireless Technology

Samsung launch 5G wireless communication: 
Samsung developed a new 5G wireless standard, it is the world's first adaptive array transceiver technology. This technology operates on millimeter wave for cellular communication. The Samsung's new adaptive array transceiver technology is a very successful project. This 5G mobile communication technology is more better than the next generation of existing 4G LTE Long Term Evaluation network technology. 5G is many times faster than running 4G networks.  As it has very high speed by which you can run internet web page in a minute and download whole film in a few minutes, it means whole new businesses can thrive and the old one will be expire or will be out of date.  5G provide 3 D movies service in mobile, 3D games and so many things.

How does it work? 
According to research it has been proved that high- frequency wave band is not suitable for mobile communication network.  In order to transver data over a long distance. It transmit data in millimeter-wave band at 28GHz frequency and at high speed up to 1.056Gbps to a distance cover which is approximately upto 2 kilometers. It uses 64 antennas.

As we know the current running 4G network works on 800MHz frequencies and also cover 2 kilometer distance but speed is lower than the upcoming 5G upcoming network technology

5G Prediction: 
New wireless standard is approximately 8 to 9 years away from today 2013. i.e 5G anticipated after 2020. We need to focus on new infrastructure of mobile technologies that could be a challenge for the advance companies. 5G is very outstanding technology will be launched soon, EU has invested more than 5 million euro in the research laboratory for 5G technology.

Microsoft eyes full control of Nook

NOOK is a digital reader. It was  published in New York City on Oct 20, 2009. In Washington, Shares of Barnes Noble surged on Thursday that Microsoft was offering a one billion dollar bid for a bookseller's Nook Media digital assets.

BN shares jumped from 26.9% to $22.55 in electronic market trades. Approximately 10 million Nook tablets as well as Nook reader have been sold. Approximately 7 million subscribers buy-e-books.

In holiday quarter revenue dropped up to 26 percent that is why just for that week the company reduced the price of its best tablet up to 35 percent off on the special promotion of Mother's Day. Barnes and Noble trying to make devices which are in competition against devices introduced by Apple, Google and other high famous name brand companies.

The stock of devices is heavily shorted. As seller borrow stocks and sell them. Due to short interest rate is high the price rate of the device will fall down? As we see the report of IDC market share data for all tablets, it is seen that Barnes and Noble has less than 2 percent in all over the market of the world.

As Stifel analyst David Schick said in a research note;

"We must be careful here because are lacking, but with devices phasing out, we see sale of the digital assets as an effective sale of the entire Nook business, unless co-owner or leasing of digital content is arranged."

Facebook Phone is Available at 99 cents Only

The news came in the social media site that HTC First best phone has been renamed as Facebook Phone. The original price of this phone is $99.99 but it is now being sold at the throw away price of 99 cent only with a two year contract with AT&T.

Although  Facebook had  launched the great feature to install Facebook Home in your Android phone,  so why  they  want to sell HTC First with this great features at this price  because Facebook wants  that the people can easily  access social media site like Facebook.

The First HTC comes with Facebook Home Software, which anyone can freely download and share it with other phones. After launching this Facebook updated its messenger software which has included multitasking features like Chat Heads. Facebook home screen allows another user to tap into their messages and friends updates and to start commenting. If you want to send alert message to your friends, so you can use Chat Heads service which has bubble headed icons in your Facebook Home Screen.

Here I want to be clear that for the research of atleast a half million people Android Smartphone and Windows Phone user told that they can easily downloaded Facebook Home Apps in their own phones, there is no needed to purchase HTC First phone for Social smartphone start screen.

Promotional pricing is common in the mobile industry. HTC doesn't comment on sales outside of our official financial announcement. A company spokesperson was quoted as saying by AllThingsD.

Root of Quadratic Formula using Function

It is very simple program to learn how to make function with parameters and call in the main body. In the previous  lesson we learn Algorithm of quadratic equation program in a simple way. But in this program we will learn quadratic equation program with the help of function. We use one function in it and this function contains three Parameters (a, b, c) in the class body. Then in the function we use bilton function in it (System.Math.Sqrt).

Now see in the Main body we take three value one by one through variable of a, b and c. Then function with the help of class first we write class name then place dot (.) then call function name. In this program function contains three parameters as we told in upper paragraph so you again write here only variable like a, b and c then display the value. If you have any problem or query then you will ask me in the below comment box.

Question: Write a program which takes two variables a, b and constant c as input from the user to calculate roots using quadratic formula. It must include two functions to return the calculated roots. 

Source Code:

class program1

        {

            public static double quardequation(double a, double b, double c)

            {

                double re = -b + System.Math.Sqrt(b * b) - (4 * a * c) / (2 * a);

                return re;

            }

        }

            static void Main(string[] args)

            {

                double re;

                double a, b, c;

                Console.WriteLine("Enter the Value a ");

                a= double.Parse(Console.ReadLine());

                Console.WriteLine("Enter the Value b");

                b=double.Parse(Console.ReadLine());

                Console.WriteLine("Enter the Value c");

                c=double.Parse(Console.ReadLine());

                re = program1.quardequation(a, b, c);

                Console.WriteLine("The Value of Quardric Equation is " + re);

        }

    }

}

Output:
