Ping (networking utility) ||This article needs additional
citations for verification. (December 2011)| Ping is a computer
network administration utility used to test the reachability of
a host on an Internet Protocol (IP) network and to measure the
round-trip time for messages sent from the originating host to a
destination computer. The name comes from active sonar
terminology which sends a pulse of sound and listens for the
echo to detect objects underwater. Ping operates by sending
Internet Control Message Protocol (ICMP) echo request packets to
the target host and waiting for an ICMP response. In the process
it measures the time from transmission to reception (round-trip
time) and records any packet loss. The results of the test are
printed in the form of a statistical summary of the response
packets received, including the minimum, maximum, and the mean
round-trip times, and sometimes the standard deviation of the
mean. Ping does not evaluate or compute the time to establish
the connection; it only gives
