Now we have all heard the term jiffy
used in everyday speech, and I
am sure most of you are familiar with
Jiffy Pop popcorn, but what exactly is
a jiffy?
A jiffy is the amount of time it takes light
to travel one centimeter, please forgive the
metric reference. A jiffy is not a metric unit
really.
A jiffy is also the time between alternating
current power cycles, generally 1/50 or 1/60 of a second.
On i386 architecture running the Linux 2.6 kernel, a jiffy
is four milliseconds.
