Speaking of large numbers - really large numbers

We just got used to gigabyte (billion) when along comes terabyte (trillion) and now petabyte (quadrillion). Some names of large numbers, such as million, billion, and trillion, have real referents in human experience, and are encountered in many contexts. At times, the names of large numbers have been forced into common usage as a result of excessive inflation. The highest numerical value banknote ever printed was a note for 1 sextillion pengÅ‘ printed in Hungary in 1946. In 2009, Zimbabwe printed a 100 trillion  Zimbabwean dollar note, which at the time of printing was only worth about 30 US dollars.
