[Techtalk] kb KB kB Kb etc!

Hi,

I'm trying to get the definitive answer to the question of life, the
universe and everything. 

Failing that, can someone help me associate these letters with their
corresponding unit of measurement.

I know that the units byte and bit are shortened to the letter "b", one
using a capital "B", the other using a lower case "b". But which one is
which?

I know that "K" and "k" refer to the SI prefix "kilo", one letter defining
kilo as being 1000, the other defining kilo as 1024. Which one is which??

Thanks!!!
