There's another "K" (capitalized) -- other than kelvins -- that
has come up over the past few decades, and that is the use of the
term K for the binary magnitude 0100 0000 0000 -- that is to say,
400 hexadecimal, or 1,024 decimal -- APPROXIMATELY, but not
exactly, 1,000. This term is used to describe anything based on
the binary system in computer-related (and perhaps other)
disciplines.
So, for example, a memory space (addressed and thus measured using
the binary system) might be denoted as "256 KB". While one might
think of this space offhandedly as being 256 thousand bytes, it is
in reality 256 x 1,024 = 262,144 bytes. On the other hand, a
communications speed of 840 kbps is not binary-based, and
therefore means literally 840,000 bits per second.
