Introducing Ping
Ping is a useful diagnostic tool that lets you quickly check if a specific computer or host is connected to the network, and is active. It sends Internet Control Message Protocol (ICMP) echo request packets to network hosts. Ping displays the response in graphical form.
You can ping more than one host but only one at a time. Each host you ping appears in the display area. In addition, you can configure Ping to initialize automatically on startup.
