nano /nan'oh/ n. cmu: from `nanosecond' a brief period of time. "be
   with you in a nano" means you really will be free shortly, i.e., implies
   what mainstream people mean by "in a jiffy" whereas the hackish use of
   `jiffy' is quite different -- see jiffy.

nano- pref. si: the next quantifier below micro-; meaning  10^-9
   smaller than micro-, and used in the same rather loose and connotative
   way. thus, one has nanotechnology coined by hacker k. eric drexler
   by analogy with `microtechnology'; and a few machine architectures have
   a `nanocode' level below `microcode'. tom duff at bell labs has also
   pointed out that "pi seconds is a nanocentury". see also
   quantifiers, pico-, nanoacre, nanobot, nanocomputer,
   nanofortnight.
