If you have looked at the Viewer Statistics (Ctrl-Shift-1), you have likely looked at PING. The term comes from the use of echo location in submarines and other marine uses. The active echo locators make a distinctive PING sound as the send a sound wave out. Electronics hear the echos coming back and create picture for human use.

When testing network connections we use a ping. It is actually a command to send a network data packet to a remote location and request a packet be sent back. The travel time tells us how well the connection is working.
What most people likely don’t think about is whether the Viewer’s PING is the same as the PING our operating system generates. For your information it isn’t.
