Ping is a basic Internet program that allows a user to verify
that a particular IP address exists
and can accept requests.
Ping is used diagnostically to ensure
that a host computer the user is trying to reach
is actually operating. Ping works by sending an Internet Control Message
Protocol (ICMP) Echo Request to a specified interface on the network and
waiting for a reply. Ping can be used for troubleshooting to test connectivity
and determine response time.
As a verb, ping means "to get the
attention of" or "to check for the presence of" another party
online. The computer acronym (for Packet Internet or Inter-Network Groper) was
contrived to match the submariners' term for the sound of a returned sonar
pulse.
