More learning

I'm back at uni note taking. Today it was physics and computing. I came across a new word - PETABYTE. Investigating this further via Google I learn that a petabyte is 1 000 000 000 000 000 bytes which apparently collates to one quadrillion (short scale) bytes or 1 billiard (long scale) bytes. What is more, petabytes aren't the largest units, there are a great many more. A whole new vocabulary of mind boggling dimensions.

Enough to drive me to need some rather strong coffee in order to try and get a handle on some of this.
