a technical term
ping checks reachability
and provides results
Funny how technical words make it into day-to-day language:
"Can you ping Fred, and see if he is on for lunch tomorrow?"
ping is a computer network administration software utility used to test the reachability of a host on an Internet Protocol (IP) network. It 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, although it is sometimes interpreted as a backronym to packet Internet groper.
Sample ping test
The following is the output of running ping on Linux for sending five probes to the target host www.example.com:
$ ping -c 5 www.example.com PING www.example.com (188.8.131.52): 56 data bytes 64 bytes from 184.108.40.206: icmp_seq=0 ttl=56 time=11.632 ms 64 bytes from 220.127.116.11: icmp_seq=1 ttl=56 time=11.726 ms 64 bytes from 18.104.22.168: icmp_seq=2 ttl=56 time=10.683 ms 64 bytes from 22.214.171.124: icmp_seq=3 ttl=56 time=9.674 ms 64 bytes from 126.96.36.199: icmp_seq=4 ttl=56 time=11.127 ms --- www.example.com ping statistics --- 5 packets transmitted, 5 packets received, 0.0% packet loss round-trip min/avg/max/stddev = 9.674/10.968/11.726/0.748 ms
