In computer networking, ping is a specific method for sending messages from one computer to another as part of troubleshooting Internet Protocol (IP) network connections. A ping test determines whether your client (computer, phone or similar device) can communicate with another device across a network. In cases where network communication is successfully established, ping tests also can determine the connection latency (a technical term for connection delay) between the two devices.
``Ping'' is one of the most useful network debugging tools available. It takes its name from a submarine sonar search - you send a short sound burst and listen for an echo - a ping - coming back. In an IP network, `ping' sends a short data burst - a single packet - and listens for a single packet in reply. Since this tests the most basic function of an IP network (delivery of single packet), it's easy to see how you can learn a lot from some `pings'.
