c.1225, "failure, failure to act," from O.Fr. defaute, from M.L. defalta "a deficiency or failure," from L. dis- "away" + fallere "to be wanting." The financial sense is first recorded 1858; the computing sense is from 1966.
How I see it, all the word 'default' means is the state an object is in if you don't mess with it. e.g. the default position of a football is on the centre of the playing field, until one of the players kicks it. They didn't need computer science for that.
