Beginning of Modern Telecommunication- Morse Code

We believe that the history of telecommunication began with the use of smoke signals. It is natural to assume it this way. It wasn’t until the early of the 1830s that electrical systems emerged. By then mankind was aware of the power in atoms and its electrons. This flow of electrons was termed Electricity. Soon …
