Definitions of 'bit'
The New Hacker's Dictionary
1. bit [from the mainstream meaning and “Binary digIT”]
1. [techspeak] The unit of information; the amount of information
obtained from knowing the answer to a yes-or-no question for which the two
outcomes are equally probable.
2. [techspeak] A computational quantity that can take on one of two
values, such as true and false or 0 and 1.
3. A mental flag: a reminder that something should be done
eventually. “I have a bit set for you.” (I haven't seen you
for a while, and I'm supposed to tell or ask you something.)
4. More generally, a (possibly incorrect) mental state of belief.
“I have a bit set that says that you were the last guy to hack on
EMACS.” (Meaning “I think you were the last guy to hack on
EMACS, and what I am about to say is predicated on this, so please stop me
if this isn't true.”) “I just need one bit from you” is
a polite way of indicating that you intend only a short interruption for a
question that can presumably be answered yes or no.
A bit is said to be set if its
value is true or 1, and reset or
clear if its value is false or 0.
One speaks of setting and clearing bits. To toggle
or invert a bit is to change it,
either from 0 to 1 or from 1 to 0. See also flag,
trit, mode bit.
The term bit first appeared in
print in the computer-science sense in a 1948 paper by information theorist
Claude Shannon, and was there credited to the early computerscientist John
Tukey (who also seems to have coined the termsoftware). Tukey records that bit evolved over a lunchtable as a handier
alternative to bigit or binit, at a conference in the winter of
1943-44.
