Ping is a computer network utility used to test network connections. It measure the round-trip time for messages sent from the host to a destination computer. It measure the reaction time of your connection, or how fast you get a response after you’ve sent out a request.
A good ping means a more responsive connection, especially in applications where timing is very important. Ping is measured in milliseconds (ms). Ping operates by sending Internet Control Message Protocol (ICMP) echo request packets to the target host and waiting for an ICMP response.
In the process it measures the time from transmission to reception and records any packet loss, too. The results of the test are printed in the form of a statistical summary of the response packets received, including the minimum, maximum, and the mean round-trip times, and sometimes the standard deviation of the mean. Ping test, on that way, determines whether your computer can communicate with another computer over the network. If network communication is established, ping tests determine the connection latency between the two computers. Ping are used to test troubleshoot connectivity problems with your home network.
The results of a ping test vary depending on the quality of the Internet/network connection. A good broadband Internet connection (wired or wireless) typically results in ping test latency of less than 100 ms, often less than 30 ms.
