Today’s digital world is all about Big Data. The cumulative figure of data is so large that trying to prove its enormity numerically would perhaps turn futile because people would find it difficult to comprehend the numbers. Instead, naming it, Big Data could make it easier to get some idea about its size. However, for those who would still be interested in numbers, it is worthwhile mentioning that according to IBM estimates every day we generate data amounting to 2.5 quintillion bytes, which is equivalent to 1018 bytes. The most exciting aspect of the enormous data is that 90% of what is on the internet today belongs to the last two years. This gives enough hints about the stupendous rate of data growth and its future.
