Word Origin & History

computer
1640s, "one who calculates," from compute. Meaning "calculating machine" (of any type) is from 1897; in modern use, "programmable digital electronic computer" (1945; theoretical from 1937, as Turing machine). ENIAC (1946) usually is considered
the first. Computer literacy is recorded from 1970; an attempt to establish computerate (adj., on model of literate) in this sense in the early 1980s didn't catch on. Computerese "the jargon of programmers" is from 1960, as are computerize and computerization.
