In computing, "latency" describes some type of delay. It typically refers to delays in transmitting or processing data, which can be caused by a wide variety of reasons. Network latency is what causes interruptions in online games.
Ping refers to the network latency between a player's client and the game server. Ping is an average time in milliseconds (there are 1000 milliseconds in a second) it takes for data to travel from a player’s device and the game server. The lower a player’s ping is, the lower the latency is and the less lag the player will experience. High ping can cause 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. In games where timing is key, such as first-person shooters 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' device and game server.
To put it in layman’s terms: Imagine you have a high ping, and you are thrown a ball to catch. Because of the high ping, it takes half a second after your brain tells your hands to move for them to react. Since you are not reacting in real time catching the ball is very difficult. That is what it is like to play a multiplayer game with high ping.
There are several factors that can impact your latency starting within your home.  It is recommended that you always use an Ethernet cable to connect your computer to your router.  Another factor impacting your latency is your physical distance to the game server.  The closer you are to the game server the lower your latency will be.
Elite Gamer is designed to help reduce your latency, reduce disconnections, and reduce lag spikes by finding an efficient path to your game server across the internet and improve performance in multiplayer games.
