Ever heard of Petabyte? Or, for that matter, Exabyte? If you haven’t, then you are going to hear a lot about them in the future. And, that’s not all. Very soon, a new word, Zettabyte, is going to make it into our glossary. Now don’t scratch your heads. We will explain. These are all terminologies pertaining to online data transfer. They are used to describe disk space, or data storage space, and system memory.
A Petabyte is a unit of information equal to one quadrillion bytes, or 1024 terabytes and an Exabyte equals one quintillion bytes. A Zettabyte is roughly 1000 Exabytes!
Staggering figures, aren’t they?
You know, 2 Petabytes would store the entire contents of all US academic libraries!!
And, it has been said that 5 Exabytes would be equal to all of the words ever spoken by mankind. There is nothing to compare a Zettabyte to, but to say that it would take a whole lot of ones and zeroes to fill it up!
You get the gist, don’t you? Now, the use of these words has come up due to the ever increasing global net traffic. The next few years are likely to witness a staggering increase, of video traffic, exponentially, such that a humongous amount of disk space will be needed to accommodate the files.
It would be hard to explain a phenomenon of such huge magnitude through words and figures. For that purpose, we have for you an infographic (posted below) created by folks at Cisco on their blog. Check it out and see if you can comprehend the future of storage space.
