Слайд 2

WRITING Since time immemorial mankind has sought ways to transfer information. Primitive people used scrap materials: somehow constituted branch signals are passed through the smoke of bonfires and more. But a breakthrough in human development was possible only with the advent of letters about 4 thousand years BC

TYPOGRAPHY How typography meet urgent human needs, showed the very first years after the invention of Gutenberg in the mid XV century. The appearance of books contributed easier information transfer. This sparked the green light to the Renaissance.

TELEGRAPH Until the mid-XIX century events and developments in other countries, people learned late for weeks and sometimes for months. The only way to transfer information over long distances was shipping mail. Meanwhile, the need for rapid communication increase. Therefore, the invention of the telegraph was the best discovery of the day. In 1832, during his trip to America created a model Morse telegraph and Morse famous.

PHONE At the end of XIX century, mankind has continued to seek new ways of rapprochement. It should been more perfect than a telegraph, a tool that would be accessible to all.

PC The emergence of computer summed up all the semantic inventions last century. He became the primary means of processing and storing information with possible transfer to any distance. But the main thing - it is extremely computer expanded our capacity for creativity.
