In today’s world where the internet has become the basic need of human beings, I do not neglect reading newspapers daily. Being a hindustantimes newspaper regular reader I get really good and technological news around the globe. I am reader of hindustantimes’s next edition, which basically targets the students audience. I am not the student but, I love to be updated with such a great edition of newspaper here in India (New Delhi). Today I am copying the news which forced me to share with my all readers. It is about the top 5 world’s fastest supercomputers. Here is the list:
