community, work team) linked by networks. In the contemporary process of individualisation, the basic unit of the network society has become the individual who is linked by networks. This is caused by simultaneous scale extension (nationalisation and internationalisation) and scale reduction (smaller living and working environments) Other kinds of communities arise. Daily living and working environments are getting smaller and more heterogenous, while the range of the division of labour, interpersonal communications and mass media extends. So, the scale of the network society is both extended and reduced as compared to the mass society. The scope of the network society is both global and local, sometimes indicated as “glocal”. The organization of its components (individuals, groups, organizations) is no longer tied to particular times and places. Aided by information and communication technology, these coordinates of existence can be transcended to create virtual times and places and to simultaneously act, perceive and think in global and local terms. A network can be defined as a collection of links between elements of a unit. The elements are called nodes, units are often called systems. The smallest number of elements is three and the smallest number of links is two. A single link of two elements is called relationship. Networks are mode of organization of complex systems in nature and society. They are relatively complicated ways of organizing matter and living systems. The characteristic of units and elements, among them human individuals, and the way they are made up, are not the focus of attention. So, networks occur both in complicated matter and in living systems at all levels. Networks are selective according to their specific programs, because they can simultaneously communicate and incommunicate, the network society diffuses in the entire world, but does not include all people. In fact, in this early 21st century, it excludes most of humankind, although all of humankind is affected by its logic and by the power relationships that interact in the global networks of social organization. Networks are not new. What is new is the microelectronics-based, networking technologies that provide new capabilities to an old form of social organization: networks. Networks throughout history had a major problem vis-a-vis other forms of social organization. Thus, in the historical record, networks were the domains of the private life. Digital networking technologies enable networks to overcome their historical limits. They can, at the same time, be flexible and adaptive
