 Also, some twitch games can be designed such that only events that don't impact the outcome of the game introduce lag, allowing for fast local response most of the time.The ping utility which determines the network latency (and therefore the risk and magnitude of lag) originates from submarine navigation in which a high amplitude audible pulse (a ping) is generated, and the detected reflection helps determine the distance and location of an enemy sub or obstruction.Ping time is the network latency between a player's client and the game server as measured with the ping utility or equivalent.
