bit
     
         (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".
     
        See also {flag}, {trit}, {mode bit}, {byte}, {word}.
