Word Origin & History

bit

related O.E. words bite "act of biting," and bita "piece bitten off," are probably the source of the modern words meaning "boring-piece of a drill" (1590s), "mouthpiece of a horse's bridle" (mid-14c.), and "a piece bitten off, morsel" (c.1000). All from P.Gmc. *biton (cf. O.S. biti, O.N. bit, O.Fris.

bite, M.Du. bete, O.H.G. bizzo, Ger. Bissen "bit, morsel"), from PIE base *bheid- "to split" (see fissure). Meaning "small piece, fragment" is from c.1600. Theatrical bit part is from 1926. Money sense in two bits, six bits, etc. is originally from Southern U.S. and West Indies, in ref. to silver wedges cut or stamped from Sp. dollars (later Mexican reals); transferred to "eighth of a dollar."

bit

computerese word, 1948 abbreviation (coined by J.W. Tukey) of binary digit, probably chosen for its identity with bit (1).

bite

having the patient bite a bullet during an operation to divert attention from pain and reduce screaming. To bite (one's) tongue "refrain from speaking" is 1590s. To bite the dust "die" is 1750. To bite off more than one can chew (c.1880) is U.S. slang, from plug tobacco.

Computing Dictionary

bit definition

unit
(b) binary digit.
The unit of information; the amount of information obtained by asking a yes-or-no question; a computational quantity that can take on one of two values, such as false and true or 0 and 1; the smallest unit of storage - sufficient to hold one bit.
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.
The term "bit" first appeared in print in the computer-science sense in 1949, and seems to have been coined by the eminent statistician, John Tukey. Tukey records that it evolved over a lunch table as a handier alternative to "bigit" or "binit".

Bit definition

the curb put into the mouths of horses to restrain them. The Hebrew word (metheg) so rendered in Ps. 32:9 is elsewhere translated "bridle" (2 Kings 19:28; Prov. 26:3; Isa. 37:29). Bits were generally made of bronze or iron, but sometimes also of gold or silver. In James 3:3 the Authorized Version translates the Greek word by "bits," but the Revised Version by "bridles."
