The Telegraph is a outdated communication system that allowed people to transmit electronic signals over wires to get out a message.
The telegraph sovled the problem of communication among long distances. which means you don't have to just send a letter or go directly up to that person to get the message.
The telegraph made life better back then because it was a new and efficient way on getting news and messages out. The telegraph improves life today because of the other inventions that it influenced such as the telephone.
The telegraph was not a simple design and at first the telegraph could only send a message 12 miles that was the problem that arose back then.
