社会变迁
New technology is a major source of social change. (Social change refers to any significant alteration over time in behaviour patterns and cultural values and norms.) Since modernization entails the social transformation from agrarian societies to industrial ones, it is important to look at the technological viewpoint; however, new technologies do not change societies by itself. Rather, it is the "response" to technology that causes change. Frequently, technology is recognized but not put to use for a very long time such as the ability to extract metal from rock Although that initially went unused, it later had profound implications for the developmental course of societies. Technology makes it possible for a more innovative society and broad social change. That dramatic change through the centuries that has evolved socially, industrially, and economically, can be summed up by the term modernization. Cell phones, for example, have changed the lives of millions throughout the world. That is especially true in Africa and other parts of the Middle East, where there is a low-cost communication infrastructure. With cell phone technology, widely dispersed populations are connected, which facilitates business-to-business communication and provides internet access to remoter areas, with a consequential rise in literacy.
