What's ping
Ping is a computer network administration software utility used to test the reachability of a host on an Internet Protocol (IP) network and to measure the round-trip time(RTT) for messages sent from the originating host to a destination computer and back. Ping is usually used to detect the actual internet speed and quality.
Sample ping test
The following is the output of running ping under Linux for sending five probes to the target host www.yahoo.com
$ ping -c 5 www.yahoo.com PING www.yahoo.com (116.214.12.74) 56(84) bytes of data. 64 bytes from 116.214.12.74: icmp_req=1 ttl=47 time=22.8 ms 64 bytes from 116.214.12.74: icmp_req=2 ttl=47 time=22.3 ms 64 bytes from 116.214.12.74: icmp_req=3 ttl=47 time=22.8 ms 64 bytes from 116.214.12.74: icmp_req=4 ttl=47 time=22.2 ms 64 bytes from 116.214.12.74: icmp_req=5 ttl=47 time=22.2 ms --- www.yahoo.com ping statistics --- 5 packets transmitted, 5 received, 0% packet loss, time 4005ms rtt min/avg/max/mdev = 22.228/22.503/22.853/0.316 ms
The utility summarizes its results after completing the ping probes. The shortest round trip time(RTT) was 22.228 ms, the average was 22.503 ms, and the maximum value was 22.853 ms. The measurement had a standard deviation of 0.316 ms.
