History of Communication

Starting from the beginning of time, cavemen communicated from noises and gestures communicated with other groups through smoke signals, the language is almost unfathomable mystery which gives rise to several theories believe that some words derive sounds of nature, or expressions of feeling like crying or joy.

The first people of the need to communicate the nature began to paint on the walls of caves and so marked the property of each tribe. As the years passed it was increasing the information and the need to pass it so we started writing "pictograph" which were symbols representing objects, each over the years began to use elements "ideographic" where the symbol is not represents only an object but also an idea and attributes associated with it. Since the drawings had meaning but not a serious phonetic signs representing specific sounds were produced.

Egyptian hieroglyphs went from "pictograms and ideograms" and developed some signs for consonants but never managed to create an alphabet. The Cyrillic alphabet is an adaptation of the Greek and Latin developed in Western countries with the domination of the Romans, with the progress of civilization and written languages ​​began distance communication by land and sea helping trade between nations and empires as writing material the Egyptians invented papyrus made ​​from the bark of the plant, while the rest of the world parchment made ​​from the skin of beef was used. Towards in 152 a.n.e Chinese paper was invented. This was a great success in Europe that caused a great demand for books. Johann Gutenberg invented the printing press that comprehensive study disproportionately. In the seventeenth century, there was what might be called in the future in the newspaper then corantos were initially contained commercial content that would progress to be news that would inform the people.

The printing techniques and applications developed by the increasingly rapid printing linotype arguably the most prominent machine. Throughout history it has always tried to develop media faster as pigeons away but the most notable would be the Persian relay system copied by the Romans.

The electromechanical telegraph morse let fly text quickly through cables also developed a code of stripes and dots that extend to everyone but you could only send messages letter by letter so they sought a way to send voice messages was achieved in 1876 with gramophone later to get on the phone.

Marconi radio with the first electric achievement send message without a physical medium as opposed to the phone or gramophone, so I patented the first radio station in 1906, in 1925 and worked six hundred radio stations worldwide.

Regarding the image with the greatest advance was kinetoscope which led to the first motion picture, then the union would sound visual images and audio. The transmission system remote motion picture begins with television, this is thanks to satellites quickly spread around the world. The greatest advance in communications - data-communication has occurred in the field of computer technology that allowed remote data transmission and communication across continents immediately with just one phone line .
