ping - Computer Definition
- A utility used to test a path from one host computer to another across an IP-based network in what is essentially a command to echo the packet from the remote host back to the originating host. Ping is an application of the Internet Control Message Protocol (ICMP). Ping was invented by Mike Muuss of the Army Research Laboratory in 1983 to diagnose an IP network problem. Muuss had done a considerable amount of work in college on sonar and radar modeling and was inspired by the principle of echo location. He named the utility after the sound that sonar makes when a signal returns.A lot of people think that ping is an acronym for Packet INternet Groper. According to Muuss, "packet internet groper" is a backronym reverse-engineered by Dr. David L. Mills. Note: Mills warns people that the clock on his wall runs backwards. I guess that explains it. See also acronym, backronym, host, ICMP, IP, radar, sonar, and utility.
- Slang for bouncing something off someone, i.e., asking someone a question, as in "Hold on just a minute while I ping Margaret and see if she'd like to join us."

(3) (Ping) A music-centric social networking feature added to iTunes for both desktop computer and iDevice users. It enables users to follow artists, establish a friends network to share music interests, view album charts and locate concerts. See iTunes.
(4) (Packet INternet Groper) An Internet utility used to determine whether a particular IP address is reachable online by sending out a packet and waiting for a response. Ping is used to test and debug a network as well as see if a user or server is online. Are You There? "Can you ping the server?" means typing ping xx.xx.xx.xx at the command line. The xx's are the four numbers in the dotted decimal IP address used to identify IP clients and servers. If the request times out, the address cannot be reached. A ping utility also typically supports DNS name resolution, and the domain name may be used. For example, ping www.computerlanguage.com would yield the same results as typing in the correct numeric address. See IP address, ICMP and DNS.
