    • Latency from a general point of view is a time delay between the cause and the effect of some physical change in the system being observed, but, known within gaming circles as “lag", latency is a time interval between the input to a stimulation and the visual or auditory response, often occurring because of network delay in online games. [1]

      Latency is physically a consequence of the limited velocity which any physical interaction can propagate. The magnitude of this velocity is always less than or equal to the speed of light. Therefore, every physical system with any physical separation (distance) between cause and effect will experience some sort of latency, regardless of the nature of stimulation that it has been exposed to.

      The precise definition of latency depends on the system being observed or the nature of the simulation. In communications, the lower limit of latency is determined by the medium being used to transfer information. In reliable two-way communication systems, latency limits the maximum rate that information can be transmitted, as there is often a limit on the amount of information that is "in-flight" at any one moment. In the field of human–machine interaction, perceptible latency has a strong effect on user satisfaction and usability.
