What is the Difference between Ping and latency?

As a metric of network performance, Ping, also known as Network Latency, is a measurement of the time that it take for a small message (or a "Ping") to be sent from your computer to another computer on the internet, then returned back to you. Ping is typically measured in milliseconds. Low numeric results or a "Low Ping" is desirable for good network performance over a "High Ping".

Ping is also the name of of command-line command that can be typed to initiate a "ping" and measure the time that it takes for the message be returned to your computer.
