Billions and Billions

Right now in my pocket is a common eight-gigabyte flash drive.  Nothing special, but handy to transfer files between computers.  I think I got it on sale for about $15.

But a gigabyte is one billion bytes.  Each byte is eight bits and each bit is stored by two transistors, so, in my pocket, are 128 billion transistors!   If each were a grain of sand, Jersey shore size, a quick calculation shows that would be over 16 cubic yards filling  three dump trucks.

Even Carl Sagan would be impressed.

P.S.  Where giga- was once only imaginable, then possible, and finally common. we now have tera- (0ne thousand giga-) becoming common.  On the horizon that you may hear of someday, if only in a crossword puzzle, are peta- (one thousand tera-), exa- (one thousand peta-), zetta- (one thousand exa-) and yotta- (one thousand zetta-).

My reasons for writing this blog are spelled out in the posting of 10/1/2012, Montaigne's Essays. They are probably not what you think.
