Global Net System

Global Net System
A global network is any communication network which spans the entire Earth. The term, as used in this article refers in a more restricted way to bidirectional communication networks, and to technology-based networks. Early networks such as international mail and unidirectional communication networks, such as radio and television, are described elsewhere.
The first global network was established using electrical telegraphy and global span was achieved in 1899. The telephony network was the second to achieve global status, in the 1950s. More recently, interconnected IP networks (principally the Internet, with estimated 2.5 billion users worldwide in 2014 ^[1]), and the GSM mobile communication network (with over 6 billion worldwide users in 2014) form the largest global networks of all.
Setting up global networks requires immensely costly and lengthy efforts lasting for decades. Elaborate interconnections, switching and routing devices, laying out physical carriers of information, such as land and submarine cables and earth stations must be set in operation. In addition, international communication protocols, legislation and agreements are involved.
Global networks might also refer to networks of individuals (such as scientists), communities (such as cities) and organizations (such as civil organizations) worldwide which, for instance, might have formed for the management, mitigation and resolval of global issues. he Canadian sociologist Marshall McLuhan was the first to forecast the huge impact of the matrix of global networks upon society, coining the term global village. His work, however, related to radio and television networks, which are broadcast (unidirectional) networks, thus predating the much larger impact of the internet.^[2]
Global networks have revolutionized human communication several times. The first to do so was the electrical telegraph. Its impact was so large that it has been dubbed the Victorian Internet. It was expanded many times in its coverage with the advent of radiotelegraphy, and with text messaging using telex machines.
The Internet and mobile communication networks have made possible entirely new forms of social interaction, activities and organizing, thanks to its basic features such as widespread usability and access, and instant communication from any connected point to another. Thus, its social impact has been, and still is, enormous. Finally, the impact on governance have been significant facilitating the emergence of 'transnational policy networks'
