Looking into Topic 2, the global nervous system basically illustrates the history of telecommunications and those individuals responsible for its outbreak. With time, we notice how the instruments used for distant communication are usually differed and improvised to welcome more electrical and electronic methods of signalling.
During prehistoric stages, early communication was shown by smoke signals, sounds of drums and later using the pigeon post. Next in 1838, the first electrical telegraph was invented by a Samuel Morse. His contributions in developing a telegraph to overcome distance in communication was made possible with his idea of Morse Code. The use of telegraph those days was supposedly the fastest way of communicating though it mostly took them days before the messages reaches the recipients. And sometime later, the idea of developing a new communicator continued. Telegraph was then substituted with telephones which made communication much more simpler as messages could be retrieved immediately. This also provided the shift in jobs as more girls were required to be telephone operators apart from the messenger boys during the telegraphic days.
Nevertheless, the use of telegraph pursued on and on. In 1894, Guglielmo Marconi had managed to build a wireless telegraphy system which created electromagnetic waves and formed radio transmissions. Even after that, the search for improved communication devices were still extended. The arrival of television- pictures in motion, satellite, computers and the Internet had remarkably changed our lives until today.
