Ping is a Terminal command that tests your connection to a host machine. Ping reports back the distance between your computer and a destination host in millisecond response times. When you use the Mac or Linux Terminal to ping a host computer, it will repeat the ping process for a long time. This is to help you find a consistent ping response time by allowing you to average out all of the results. You can stop a ping command using a keyboard combination.
Open "Terminal" on your Mac or Unix system.
