computer network administration utility used to test the reachability of a host
via Wikipedia infobox
Ping is a network management software utility used to test the reachability of a host on an Internet Protocol (IP) network. It is available in a wide range of operating systems.
Ping measures the round-trip time for messages sent from the originating host to a destination computer that are echoed back to the source. The name comes from active sonar terminology that sends a pulse of sound and listens for the echo to detect objects under water.
