Hexidecimal

[bruce plecan]

Is there something like hexidecimal for dummies?, or is this simple,
a computer has 16 fingers instead of 10. Does 8 (fingers) make a hand 
(for the computer) full, that would be the same as saying the 5 of human
hands.  So 8 ozs of gold in hexidecimal weight the same as 5 oz of gold
in our "normal" system.
  Just want to make sure I got it right, before it goes into the 
archives.
  Again Thanks  Bruce   nacelp at bright.net
