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." 2. bit (2) computerese word, 1948 abbreviation (coined by J.W.
