What Is a Computer Ping Test ?

***  A ping test determines whether your computer can communicate with another computer over the network. Then, if network communication is established, ping tests also determine the connection latency (technical term for delay) between the two computers.

*** Ping test works by sending ICMP  "echo request" packets to the target host and listening for  replies. Ping measures the round-trip time and records any packet loss, and show when finished a statistical summary of the echo response packets received, the minimum, mean, max and in some versions the standard deviation of the round trip time.

***  You can use a ping test to troubleshoot connectivity problems with your home network. Ping tests are also commonly used to measure the delay ("lag") with online gaming services or other Internet servers.
