| bit (bĭt) Pronunciation Key
The smallest unit of computer memory. A bit holds one of two possible values, either of the binary digits 0 or 1. The term comes from the phrase binary digit. See Note at byte. |
bit 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
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."
bit
In addition to the idiom beginning with bit, also see a bit; champ at the bit; do one's bit; every bit; not a bit; quite a bit; take the bit in one's mouth; two bits.
