To test whether your computer has connectivity to the network, you can use the ping command followed by a known IP address or domain name. For example, you can type ping 8.8.8.8 (which is a Google DNS server) or ping www.google.com in the command prompt. This command sends packets to the specified address and displays the response time, indicating whether the network connection is functioning properly. If you receive replies, your computer is connected to the network; if not, there may be connectivity issues.

You should see response times.The etymology is from ping-pong. You send a ping from one computer to another, it sends a pong back.

Redo remains enabled until the undo history is empty, or another command besides undo is selected, at which point the repeat command should be enabled again.
