The telegraph is a device for communicating over a distance. It uses electricity to send coded messages through wires. In the middle of the 1800s the telegraph was the fastest way to communicate over long distances.
An American artist and inventor named Samuel F.B. Morse created Morse Code in the 1830s. Before his invention, an important message could take weeks to reach its destination.
Morse Code and the telegraph allowed people to receive information sent from far away in just minutes. Newspapers, railroads, and businesses used the code and the telegraph to send news quickly from one city to another.
Morse Code uses dots, dashes, and spaces to represent letters, punctuation, and numbers. The symbols are arranged to spell out a message. A telegraph converts the symbols into electrical signals and sends them across a wire to their destination. The signals are then converted back into the message by the telegraph that receives them.
