Ping
Ping is a command you can use to check whether your PC can recognize other
computers on your network and the Internet. A ping command will send a message to
the computer you specify. If the computer receives the message, it sends messages

trying to communicate.
On Windows-based computers, you can execute a ping command from the Start
menu. Click the
Start
button, and then click

text box, type a
statement such as the following:

If the target computer receives the message, a
Command Prompt
window is
displayed:
If the target computer cannot be located, you will receive the message
