Ping is a basic Internet program that lets you verify that a particular IP address exists and can accept requests. The verb ping means the act of using the ping utility or command. Ping is used diagnostically to ensure that a host computer you are trying to reach is actually operating. Ping can also be used with a host that is operating to see how long it takes to get a response back.
Ping operates by sending a packet to a designated address and waiting for a response.
The computer acronym was contrived to match the submariners' term for the sound of a returned sonar pulse. This is done before sending e-mail in order to confirm that all of the addresses are reachable. Bringing you the best technology specific search engines.
