Telegraphy.

Electricity completely changed communications. Once it was discovered that electric current flows along a wire, it seemed possible that it could be used for messages. As long as two places were connected by a wire electric impulses could be sent along it. It meant that people were able to send messages a long way at great speed. The new way of communication had a lot of advantages and by the end of the 19^th century cables were laid all over the world.

Samuel Morse, one of the most famous people in communications, invented a special code, which we call now "the Morse code". He thought of using short and long electric impulses. Combining different sets of impulses he made a code for the whole alphabet, and the numbers from 0 to 9. This code, was the easiest and the fastest to transmit.

Later on the necessity aroused to increase the speed of sending messages. People decided to use the fact that current could flow one way round the circuit or the other. A new system called double current working" was worked out According to this system a dash and a dot are impulses of the same length but of different directions.

Then a machine was invented to send typewriter messages over a telegraph circuit. Such machines are called teleprinters or teletypes and use International 5-unit code instead of the Morse code. Each letter or figure is made up of five impulses of electric current, either positive or negative, all letters being the same length in time. A teleprinter has a keyboard and every- time one of the keys on the keyboard is pressed it sends the five impulses that make one letter or figure.

As most modern systems use alternating current, one line can be used to send many messages at the same time. It is possible if each message is sent out at a different frequency. This allows high-speed telegraph communication as well as transmission of written messages.
