Basically it's a measurement of connection speed, and it influences lag quite a lot.
You can test the latency of your internet connection by using Speedtest.net, the most popular online speed test. (Fun fact: Speedtest was even featured in one of the Iron Man films.) Anything below a ping of 20ms is considered to be great, while anything over 150ms could result in noticeable lag.f you have a ping of 98ms (milliseconds) that's the time it has taken for your computer to respond to a request by another computer.
