Brief high-pitched sounds or signals; in computing, network packets sent to test connectivity between devices.
Onomatopoeia imitating a short, sharp sound. Computing usage emerged from sonar terminology where 'ping' described the sound pulse used for detection, adapted for network diagnostics in the 1980s.
The computer 'ping' command was named after submarine sonar pings because both send out a signal and wait for a response to measure distance or connectivity. This naval metaphor perfectly captured the essence of network communication testing.
