There is a new breakthrough and we can now expect our internet getting 100 times faster. Scientists at University of Sydney have taken four gruesome years to develop it but now, due to a small scratch on a piece of glass they say our internet is going to be faster than current Telstra networks.

The scratch means we will have almost an instantaneous access to the Internet which will be error-free anywhere in the world. 

"This is a critical building block and a fundamental advance on what is already out there. We are talking about networks that are potentially up to 100 times faster without costing the consumer any more," says Federation Fellow Professor Ben Eggleton, Director of CUDOS, based within the School of Physics at the University of Sydney.

Eggleton, whose team beat their deadline by a year, says that up until now information has been moving at a slow rate but optical fibres have a huge capacity to deliver more. "The scratched glass we've developed is actually a Photonic Integrated Circuit," he says.

"This circuit uses the 'scratch' as a guide or a switching path for information - kind of like when trains are switched from one track to another - except this switch takes only one picosecond to change tracks. This means that in one second the switch is turning on and off about one million million times. We are talking about photonic technology that has terabit per second capacity."

This initial demonstration proves it is possible to achieve speeds 60 times faster than current Australian Networks. With further development, the process is likely to produce even faster results.

"Currently we use electronics for our switching and that has been OK but as we move toward a more tech-savvy future there is a demand for instant web gratification. Photonic technology delivers what's needed and, more importantly, what's wanted."

hi all these are some questions.......... i will be answering them in the next thread.... till then allow your brain to work....

Q1 int checkzero(int a[], int n)

{

int i;

for(i=0;i<n;i++)

{

    if(a[i]==0)

    {

        return(TRUE);

     }

    }     

   return(FALSE); 

}

Now it checks for every element in array a and does n comparisons to find presence of a zero element

no solve this by doing only one comparison.

 Q2 int func(int n)

    {

        if(n<=1)

         {

              return(1);

         }

         else

          return(n*func(n-2));

}

}

what will be the output of x=func(11);

 

Q3 how to check whether a no. is a power of 2? write a c code?

 

Q4 write a c function to generate the nearest integer value 

int nearestint(float f) 

Keywords: interview, interview question, power of 2

hi all i am writing this post based on my personal experience.

I appeared for the tcs placement examination around a month ago. The written exam was held on computer.

 I flipped through the questions in each section, clicking the next button and reached the end completing all the questions. As i was about to press the submit button there was some virus problem in my system and hence i was not able to press the finish button. I reported the matter to the tcs personnel, who very confidently said " arey its not a problem your paper is evaluated question by question, so even if you dont press the finish button your score is calculated"..... I was pretty amused upon listening this reply, as all my computer logic failed to explain this reasoning given by him. Anyhow it was my first placement so i couldn't revolt. But before leaving the hall i made sure that i reported this matter to all the tcs officials present there.

After about an hour the name of shortlisted candidates for the interview were announced. Every other classmate of mine made it to the second stage except ME, which made me very sure about the fact that my computer logic hasn't faultered. I went with the placement coordinators of my college to the tcs people, and requested them to let me appear for the exam again (as its computer based so the question paper was randomly generated). 

After some degree of persuation they agreed. I cleared the written as well as both the interview rounds and now am placed in TCS.

So guys if such a problem happens with you give the tcs people this reference and let them check this post if they dont beleive.

Written exam was aptitude+english based.

These are the few question which i remember:

In the technical interview they first asked me my areas of interest, which inculed PHP,C++,data structures and operating system

First question asked was the insertion sorting problem and its advantage (always remember to say that insertion sort takes O(n) time to sort a list that is already sorted)

Then they asked about virtual memory and paging.

Then they asked me to brief them about my websites. 

Next question was  trick, they asked me the difference between "internet" and "Internet"

i told them that you mean to say a small 'i' internet and a capital 'I' internet they said yes.

so i told them the usual difference that one is our web and other is Internetwork, so one guy was constantly smiling and said tell me a bigger difference, tell me a major difference. i said thats all. So the person said one is an internet with capital'I' and other is a small one.

i replied yes sir thats what i told you initially. Anyways it was a very light interview with a lot of knowledge sharing .

The next was the HR interview. they asked me few questions about how to be a good communicator, how to handle your team members and few other general questions. 

That was my experience of tcs (will be sharing other company's experiences shortly). 

Thank you
