NetPinger Pro (NPP) uses the Ping command to test the response from three public servers managed by Google, Level 3, and OpenDNS. (See "What is Ping?" Below for explanation.) Each server responds to intervals you can set - usually five seconds. By default, NPP uses the so-called Blocking call to allow the server to respond.
Ping is a command available for all types of computers that tests whether another computer on the web will respond to your request. This is called the sound of underwater sonar systems - they send a "ping" sound that bounces off the target and listening to that echo - they find their purpose. Internet "ping" works in a similar way. Define your goal, an Internet server, and listen to it.
