PING

Ping is a Unix utility that sends ICMP ECHO to the server ( destination machine ) from the client ( originating machine ). It takes its name from a submarine sonar search – you send a short sound burst and listen for an echo – a ping – coming back. There is a myth that Ping is actually an acronym for the words ‘Packet INternet Groper’, but there is no proven evidence to support the statement.
