Ping

Ping is a computer network tool used to test whether a particular host is reachable across an IP network. Ping works by sending ICMP echo request packets ('Ping?') to the target host and listening for ICMP echo response replies (sometimes dubbed 'Pong!' as an analog from the Ping Pong table tennis sport.) Using interval timing and response rate, ping estimates the round-trip time (generally in milliseconds although the unit is often omitted) and packet loss (if any) rate between hosts

The amount of time it takes for data to travel from your computer to the server AND back. This is usually measured in milliseconds.

Abbreviation for packet Internet groper. In TCP/IP, a protocol function that tests the ability of a computer to communicate with a remote computer by sending a query and receiving a confirmation response.
