Electromechanical Age (1840-1940)

This era starts when man discovers a way in which the information can be converted to electrical impulses and how to control and use the electricity.

     The first electronic calculating device was the Colossus machine  used by the british and and germans.

       Then we have the beginnings of telecommunications like:

Alessandro Volta invented the voltaic pile, the first source of stores electricity in the 8th century.

The telegraph made by Samuel F. J. Morse in 1832.

The radiotelegraph created by Marchese Guglielmo Marconi

The telephone and radio, on 1876 the first successful bi-directional transmission of clear speech took place.

And finally between the years of 1939-1944 the United States financed the first "complete turing" computer called Mark 1.
