D.1.1 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 sends a message to the computer you specify. If the computer receives the

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