There is so much data being produced and stored at such a rate that eventually we may run out of words to describe it. From mega to giga to tera to peta, the prefixes we use to describe piles of bytes are starting to run out. Gigabyte was an enormous amount of space to have on your computer, and terabytes were strictly for scientists and companies like IBM. A terabyte (or several) is now standard for personal use, and petabytes are what we talk about when we have to make a point about how much data is stored by Facebook and Google. And soon those terms won't seem so big, either, as we move on to exabytes. The problem is that after exabytes, we have zettabytes, and then yottabytes, and then — nothing. It is truly mind-boggling.
