High ping and low ping are commonly used terms in online gaming, where high ping refers to a ping that causes a severe amount of lag; while any level of ping may cause lag, severe lag is usually caused by a ping of over 100 ms.[1] This usage is a gaming cultural colloquialism and is not commonly found or used in professional computer networking circles. In games where timing is key, such as first-person shooter and real-time strategy games, a low ping is always desirable, as a low ping means smoother gameplay by allowing faster updates of game data between the players' clients and game server.
