To reach this purpose, the various English and Persian literatures have been investigated to complete the findings as well as statistics of databases such as UNESCO and International Telecommunication Union (ITU). The results show that the information infrastructures in developed countries are more advanced than the other places of the world such third world countries; in addition, the first group countries (developed countries) have a considerable distance with the second group countries (third world countries) in terms of the internet clienteles, accessibility, bandwidth and speed, penetration rate, usability cost, and dissemination. Political, social, economical, and cultural different factors have played an important role in developing and disseminating these infrastructures but the economical factors (and expensive costs of modern information technologies) are the most important factor among the other factors. Although there is a significant distance between developed and developing countries, but in recent years developing countries have increasingly progressed in developing and disseminating of information infrastructures.
