What is meant by ping command?What it does?

[Bryce W]

The Ping command is a network diagnostic tool. It can determine if a computer/network device is working and the speed it took for the signal to get there.

For example, if you were trying to connect to a website but it appeared to be not working. You could ping the websites server to see if the server is online. If it doesn't respond to ping its quite possible that the server is down.
If it does respond to ping it'll show you how long it took for your signal to get to the server and back. This is a good way to check to see if your internet connection is slow.

Here I did the ping command to the Technibble server. Since I got a reply it means that the Technibble server is running fine. The part that says "time=229ms" tells me how long it took for the signal to get back to me. 229ms for my connection to go from Australia to America is OK, but not great.
