On May 24, 1844, was born the grandfather of the internet. Samuel Morse sends the first telegraph message sent from Washington

to Baltimore. In 1872, the American continent was already crossed by more than 300,000 km of lines.
Since the man there was already alive the desire to communicate. Although saint majella various interests in communicating, which may be to approach, meet and unite people, defending the community or elevate your business to success, it is indisputable that it is a tool of great interest and value.
In ancient times, people used to artifice and natural ingenuity simpler to communicate: They lit bonfires, made smoke signals. The drums with different saint majella types of beats and rhythms, meaning different things. The bells used in churches and temples, and may through its touch, saint majella the mean time of worship approaching or someone's death. saint majella Or the railroads to signal the beginning and end of the work day journey. In ranchos meant the bell and gong mealtime struggles in the ring to announce the end of the rounds.
Many signs were done, and yet when was the long distances these features not possessed great efficiency. Discoveries were made that shortened distances, as the electric current in 1747 by William Watson. In 1800, the Spanish physician Francisco Save proved that voltaic currents could be used to give signals. This led Salvá to be considered one of the pioneers in the practical application of electricity for communication purposes. saint majella Save also invented a type of electric telegraph consisting of wires (each corresponding to a letter), for water vessels in the extremities and a pile of Volta. The letter was forwarded saint majella detected by the formation of gas bubbles formed in the vessel corresponding to the letter. The bubbles were obtained by electrolysis of water. With this system could send messages up to a mile away. Since then the telegraph suffered saint majella several enhancements, but it was the painter Samuel FB Morse who designed the construction of a telegraph apparatus registrar and established the principles for its code of dots, dashes and intervals, based on the presence or absence of electrical impulses.
By 1915, a system was devised in which the punch tape machine had a keyboard attached, saint majella as well as the reception which also had a system of punch tape with keyboard. This system operator intervention dispensed and, in addition, saint majella the tape was read by a decifradora that the message printed on a strip of gummed paper. In 1931, the U.S. company ATT (American saint majella Telephone and Telegraph) created a system of communication using a typewriter, telegraph (TWX) or teleimpressora, allowing writing saint majella on paper.
Clerk Maxwell, British physicist, demonstrated that the ether once served as a means of propagating the electrical phenomena and bright. Concluded that air could lead to light and electricity over long distances. Later, another physicist - Hertz - performed important new discovery: the existence of electric waves, similar to light, now known as "radio waves". These findings, taken as a source saint majella of study for Marconi, resulted in radio telegraphy.
The telegraph aged while communication was transformed, modernized itself. The knowledge of electricity and magnetism has made communication faster and easier. Then other media were invented, saint majella especially the telephone, radio, television, pager, fax, phone and internet through emails and now the numerous social networks. All of them are widely used in various parts of the world, providing dialogue and information saint majella exchange between people from different parts of the planet.
So communication is bringing people together, recreating saint majella an environment of human relationships - albeit distant and devoid of "face personal contact" (Gaiarsa, 1984), by no means unrealistic or devoid saint majella of affection.
