Yottabyte

I was surfing the internet the other day... actually, I was looking for the meaning of the number in like the third column of the ls -al command to list the files of a directory and their sizes, creation dates, etc. I was curious whether it was bytes, bits, or what.. Excuse me, I digress.

I stumbled across a cool web page that states that a yottabyte is everything there is to know. I thought it was neat, and then I wanted to show Nathan. When I couldn't find it easily, that's when I knew it had to go on the blog.

The site didn't seem very fancy (meaning it might die before blogspot does), so I have reproduced the page below. Here's the link to the original page: http://www.uplink.freeuk.com/data.html
