What is pinging?

Thank you Alice for that def

For those of us still living in the 20th century however you might also def "web page," "web crawling," "bot," "crawl," and "index"

The definition offered by the OP, in his or her somewhat pointless post, is one, somewhat secondary, meaning for the word "pinging". What most IT specialists understand by the word is using a computer network administration utility (called Ping) to test the reachability of a host on an Internet Protocol (IP) network and to measure the round-trip time for messages sent from the originating host to a destination computer. The name comes from active sonar terminology which sends a pulse of sound and listens for the echo to detect objects underwater.
