Telegraphs

The Telegraph was a way to communicate to people from a long distance without the use of Pigeon Post. Before the making of the Telegraph civilizations like the Greek and Chinese used signals using smoke or beats from a drum.

The disadvantage of this was that the weather would affect the effectiveness that these signals would work including the Semaphore. The Semaphore held a series of hilltop stations, on these stations movable hands would be situated to make signals like letters or/and numbers. The stations would also have a pair of telescopes so that they would be able to see the signals being made from other telegraphs.

And because these signals visuality were weakened by weather others methods were created so that effective long distance communication could be produced. In the 19th century electricity was introduced and many inventions had been made using this new resource, one of these inventions were the Electronic Telegraph.

The research done by Sir William Cooke, Sir Charles Wheatstone, Samuel Morse, Leonard Gale and Alfred Gale had been used to create the electronic Telegraph. Sir William Cooke and Charles Winstone created a telegraph system which used five magnetic needles which would point to panels of letters or numbers, this used an electrical current. This telegraph system was later used for railroad systems in Britain.

Samuel Morse although had created another telegraph system using a single circuit telegraph which would function when the operator key would be pressed. When the key was pressed it would send an electrical signal to a receiver. To use this telegraph all it needed was a key, a battery, wire and a line of poles between stations for the wire and receiver.

This was later called Morse Code this was named after Samuel Morse. Letters and numbers were sent using codes like dots and dashes. The codes were marked by marks on a piece of paper which would be translated into english by the telegraph operator. But when time passed the operators were able to hear the code and translate the code by hearing the clicking of the telegraph and thus a receiver was made for the telegraph which created noises which made listening to the code easier.
