[citation needed] The lower one's ping is, the lower the latency is and the less lag the player will experience. 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 indicated by a ping of over 100 ms.

Latency in optical fiber is largely a function of the speed of light. This would equate to a latency of 3.33 μs for every kilometer of path length. The index of refraction of most fiber optic cables is about 1.5, meaning that light travels about 1.5 times as fast in a vacuum as it does in the cable.
Input lag or input latency is the amount of time that passes between sending an electrical signal and the occurrence of a corresponding action.. In video games the term is often used to describe any latency between input and the game engine, monitor, or any other part of the signal chain reacting to that input, though all contributions of input lag are cumulative.
The domain speedtest.net has been used to host a speed test since 2000, and was acquired by Ookla in 2006. [12] As of 2011, Ookla claimed 80% market share and was one of the top 1000 most popular websites. At the time, Ookla derived its revenue primarily from fees paid by companies to license custom speed test and proprietary testing software.

This lag time has been measured as high as 68 ms, [1] or the equivalent of 3-4 frames on a 60 Hz display. Display lag is not to be confused with pixel response time, which is the amount of time it takes for a pixel to change from one brightness value to another. Currently the majority of manufacturers quote the pixel response time, but neglect ...

For example, the original tracker ball mouse used a metal bearing pressed against two rollers to track movement. [2] Much research and technology has gone into what type of tracker provides the most accurate depiction of the user's movement. With the advent of the World Wide Web, mouse tracking was expanded to include click data. Researchers ...
