As our world gets more and more complex, we tend to transfer that to the virtual world of ones and zeros. As we clear up more space in the real world, the complexity of the things we virtualize becomes ever greater in size. A great example of this are all the photos that millions of us take each and every day of our lives. With the digital camera comes an ever growing number of photos being uploaded, and for each day that goes by, the resolution of those photos becomes ever greater. So as you canimagine, the storage space needed to fill up everything that we create each day is skyrocketing to levels where we are soon going to be talking about terabytes, zettabytes and even exabytes.
