ping (n.)

1835, imitative of the sound of a bullet whistling through the air or striking something sharply. Meaning "short, high-pitched electronic pulse" is attested from 1943. As a verb from 1855; in computer sense is from at least 1981, based on earlier use of the word in reference to a submarine sonar pulse, in which it might combine the sound-word and ping-pong (which also is based on sound). Related: Pinged; pinging.
