What is ping?
Ping is important for testing how long it takes data to travel from your computer, go across the various Internet connections and nodes, reach the computer on the other side, and get back to you. This data is then calculated to determine how fast the connection is to the other computer and how quickly a particular data transfer can be completed.
The ping rate, which is also known as latency, is a number that corresponds to delay time on the Internet measured in milliseconds (30ms, for example). The higher the number, the more data transfer delays you might experience, and sense, while you’re online. If you play online games, especially first-person shooting or driving games, then you want the latency to be less than 30ms. For the rest of us, anything under 100ms would be good enough.
