Internet is managing to reach every part of the globe in some manner, including countries with restrictive governmental regimes, like North Korea. As the number of internet users increase, so too do the numbers associated with their traffic.
Cisco estimates this, and the figures they have produced are quite astonishing to look at. By 2015, they expect that global internet traffic will reach the zettabyte threshold annually. What is a zettabyte? 966 exabytes. What is an exabyte? About 1,000,000 terabytes.
