4G Technology

Fourth Generation (4G) mobiles4G also called as Fourth-Generation Communications System, is a term used to describe the next step in wireless communications.

 A 4G system can provide a comprehensive IP solution where voice, data and streamed multimedia can be provided to users on an "Anytime, Anywhere" basis.


The data transfer rates are also much higher than previous generations.


The main objectives of 4G are:


1)4G will be a fully IP-based integrated system.


2)This will be capable of providing 100 Mbit/s and 1 Gbit/s speeds both indoors and outdoors.


3)It can provide premium quality and high security.


4)4G offer all types of services at an affordable cost.


4G is developed to provide high quality of service (QoS) and rate requirements set by forthcoming applications such as wireless broadband access, Multimedia Messaging, Video Chat, Mobile TV, High definition TV content, DVB, minimal service like voice and data, and other streaming services.


4G technology allow high-quality smooth video transmission. It will enable fast downloading of full-length songs or music pieces in real time.


The business and popularity of 4Gmobiles is predicted to be very vast. On an average, by 2009, this 4Gmobile market will be over $400B and it will dominate the wireless communications, and its converged system will replace most conventional wireless infrastructure.


Data Rates For 4G:


The downloading speed for mobile Internet connections is from 9.6 kbit/s for 2G cellular at present. However, in actual use the data rates are usually slower, especially in crowded areas, or when there is congestion in network.

4G mobile data transmission rates are planned to be up to 20 megabits per second which means that it will be about 10-20 times faster than standard ASDL services.


In terms of connection seeds, 4G will be about 200 times faster than present 2G mobile data rates, and about 10 times faster than 3G broadband mobile. 3G data rates are currently 2Mbit/sec, which is very fast compared to 2G's 9.6Kbit/sec.

Forget Windows: Midori is coming

WINDOWS is a name that has ruled the whole computer world since its first launch in November 1985. Since then it is like a trademark of Microsoft Corporation.

With many advanced versions of Windows available today such as Windows XP, Windows Vista, it is the most used operating system in the world.


Yes, MICROSOFT is working on a new generation of operating systems called Cloud-Based Operating System and rumors are there that MIDORI will be their first such operating system, which will replace Windows fully from computer map.

WHAT'S THE DIFFERENCE

MIDORI is an offshoot of Microsoft Research's Singularity operating system.

 In this the tools and libraries are completely managed code.

MIDORI is designed to run directly on native hardware (x86, x64 and ARM), will be hosted on the Windows Hyper-V hypervisor, or even be hosted by a Windows process.

MIDORI can be also seen as MICROSOFT'S answer those competitors who are applying "Virtualization" as a mean to solving issues within contemporary computing.

The main idea behind MIDORI is to develop a lightweight portable OS which can be mated easily to lots of various applications.

IMPORTANCE OF MIDORI

For knowing the importance of MIDORI you have to think about, how an operating system is loaded on a computer.

Actually operating system is loaded onto a hard disk physically located on that machine. In this way, the operating system is tied very tightly to that hardware.

As Windows is dependent on hardware, it might face opposition from contemporary ways of working because people are extremely mobile in using different devices in order get diverse information.

Due to this trend installing different applications on a single computer may led to different compatibility issues whenever the machine require updating.

The new operating system will solve these problems by the concept of Virtualizing.

This will solve problems such as widespread security vulnerabilities, unexpected interactions among different applications, failures caused by errant extensions, plug-ins, and drivers and many more.

Can U debug?? just (C) try this...

1.What is the output?

enum colors {BLACK,BLUE,GREEN};
main(){
  printf("%d..%d..%d",BLACK,BLUE,GREEN);
  return(1);}
         
A.. 0..1..2                                                                                                                           

 B. 1..2...3

C. Will not compile

2. Predict the output

#define int char
main(){
            int i=65;
            printf("sizeof(i)=%d",sizeof(i));}

A. sizeof(i)=1

B. sizeof(i)=65

C sizeof(i)=2

3. Judge the output

#define square(x) x*x
main(){
int i;
i = 64/square(4);
printf("%d",i);}

A..4                B.64      
 C.Compilation error

4. Does the following program generate error?

 #include<stdio.h>
#define a 10
main(){
#define a 50
printf("%d",a);}
A. Yes               B. No
           

5.What is the output

#define f(g,g2) g##g2
main(){
          int var12=100;
          printf("%d",f(var,12));
}

A. Compilation error                                                                                                                   B.100                                                                                                                                                    C.12

A new way of Politics - Like MUDHALVAN Film

A journlist and popular television anchor A William Rabi Bernard is the AIADMK candidate for the July 22 byelections to fill up the lone vacant Rajya Sabha seat from Tamil Nadu.

LOK-PAL

The word Lokpal has been derived from the Sanskrit words "loka" (people) and "pala" (protector/caretaker). So the word Lokpal means 'protector of people'. The concept of Lokpal has been drawn up to root out corruption at all levels in the prevailing Indian polity.

After 42 years, the Jan Lokpal Bill is still pending in India. The first Lokpal Bill was introduced by Shanti Bhushan and passed in the 4th Lok Sabha in 1969 but could not get through in the Rajya Sabha, subsequently, Lokpal bills were introduced in 1971, 1977, 1985, 1989, 1996, 1998, 2001, 2005 and in 2008, yet they were never passed and it is pending.

The Lokpal Bill provides for filing complaints of corruption against the prime minister, other ministers, and MPs with the ombudsman.However, while it was pending in the Rajya Sabha, the Lok Sabha was dissolved so the bill was not passed at that time. The bill was revived in 1971, 1977, 1985, 1989, 1996, 1998, 2001, 2005 too.
