What is Ping?

Ping calculates the round-trip time of the data packet's route from it's source to the destination and back,and determines whether any packets were lost during the trip.Lower ping is better one. Because if you have any high,your internet speed will be reduced.Then you can't play any online game.You can check your game server ping using http://www.whoisxy.com/ping.aspx

ping is a computer network tool used to test whether a particular host is reachable across an IP network. Ping works by sending ICMP “echo request” packets ("Ping?") to the target host and listening for ICMP “echo response” replies (sometimes dubbed "Pong!" as an analog from the Ping Pong table tennis sport.) Using interval timing and response rate, ping estimates the round-trip time (generally in milliseconds although the unit is often omitted) and packet loss (if any) rate between hosts.
