In the Electromechanical age developed the Telephone and the Radio eTc... this age consist of different inventors and when thier invent it.That until now they are still inventing some devices that can help us into our modern technology.♣♠

THE TELEGRAPH

I learned that Samuel F.J. Morse concieve of his version of an ELECTROMANETIC TELEGRAPH in 1832 and constructed an experiment version 1815. He did not construc a truly practical system until 1844,when he built UNE from baltimore to washington.
