In multiplayer online video games, MMOS, MMORPGS, MMOFPS and FPS Ping is often conflated with latency. High latency can cause lag. One may "lag out" due to unacceptably high ping. It poses a detriment to others' gameplay. Similarly, client software will often mandate disconnection if the ping is too high. A high ping is not the result of lag; rather, a high ping causes lag. It may also make servers crash because of the stability. In some games, users with a high ping unintentionally gain an unfair advantage, as in some implementations of the Quake III Arena network protocol and game engine. In these games, the player aided by the higher ping skips around, almost looking like they are teleporting, making it hard to judge where the character is exactly, and thus more elusive to target. For this reason, many servers automatically remove players with higher than average ping - with thresholds as low as 130 milliseconds. Some factors that might affect ping include: network protocol engineering, Internet connection speed, the quality of a user's Internet service provider and the configuration of firewalls. Ping is also affected by geographical location. For instance, if someone is in India, playing on a server located in the United States, the distance between the two is hardware in between the two computers is often more significant. For instance, wireless network interface cards must modulate digital signals into radio signals, which is often more costly than the time it takes an electrical signal to traverse a typical span of cable. The lower the ping the better.
