There is no doubt we all heard about gigabyte, terabyte or even exabyte, but to be honest, I never heard of the term zettabyte before. Zettabyte is actually equal as 1 trillion gigabytes. That really sounds absurd and crazy when you grasp it in your mind. Increased transfer of data and telecommunication are facing bright future. It is estimated that by the end of this year traffic on the Internet will surpass over 1 zettabyte.
