Motivation for proposed prefixes for binary multiples
In the past, computer professionals noticed that 1024 or 2^10 (binary) was very nearly equal to 1000 or 10^3 (decimal) and started using the prefix "kilo" to mean 1024. That worked well enough for a decade or two because everybody who talked KB knew that the term implied 1024 bytes. However, almost overnight a much more numerous "everybody" bought computers, and the trade computer professionals needed to talk to physicists and engineers and even to ordinary people, most of whom know that a kilometer is 1000 meters and a kilogram is 1000 grams.
