Ping

Ping
1. Ping is a widely available network utility for performing a simple network connectivity test between the current network location and a remote one. It works by generating an ICMP echo-request packet, and then listening for the reply from the remote end. A ping test is used to establish that communications can be successfully established between two computers on a TCP/IP network.

Ping was originally named after the "ping" from sonar. The idea was later introduced that it stood for "Packet INternet Groper".

2. Some network games display a "ping count", "ping value", "ping" or "pinging" value. This is an indication of how long it takes to send a packet of information to a remote computer and get a reply. The values are typically in milliseconds. For game play generally the lower the ping count the better.
