Another interesting topic which I had to go and google to understand a bit more of .( and justify why I am still on a 32bit machine)
From WIKI we went from 4 bits(1970) to 32 bits (1985) and 64 bits (1993) - ( mainstream availability)
So in around 20 years we went from-
4 bits = 16 (integers)
8 bits = 256
16 bits = 65,536
32 bits = 4,294,967,295 ( no idea how it ends in 5 - i'm only pasting from wikipedia)
64 bits = 18 446 744 073 709 551 616
Its now 20 years on and where are the 128 bit machines? (There are currently no mainstream general-purpose processors built to operate on 128-bit integers- again from wikipedia)
128 bits = RBN (really big number xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx etc)
So , even though 32 bit is adequate for most of us , the fact that 64 bits is going to be around for a long time (possibly forever) is justification for its uptake - me thinks.
Thanks Jim for getting my brain cell moving and now I have some understanding.
