Diagnose connectivity issues with the Linux ping command

Networked computers are so common these days that most of us take it for granted that a computer on one side of a room can contact one on the other side of the room, much less the other side of the world. When it works as designed, networking is what makes the Internet, the cloud, file shares, media streaming, remote administration, printing, and much more possible.
