It is difficult to define what exactly is the technology. In principle the term literally refers to the study of the technique, that is, to all the theoretical or practical knowledge involving the scientific disciplines. According to this definition, something is to be a technology as such, you must have a use in a particular field. At the time that no longer used, it would be technology. Like that is pretty hard to categorize, we tend to talk about obsolete technologies or obsolete. No need to go to the time of the invention of fire to see technologies that have been replaced by others: that to our grandparents it was technology for our generation can be an anachronism without practical use. There is another concept used today such as new technologies, involving various fields of recent creation as computer science, telecommunications. Anyway in modern ...view middle of the document...
In the life of modern society, technology is indispensable. In fact, most of the scientific efforts are focused on the creation of new technologies that meet the needs of society and will raise the level of well-being. That on paper, because not always the technology is used for the intended purpose and is designed to improve human life (there are important exceptions, such as military technology), but always a technology meets a need. Without technology is not precise, and therefore, it will be not used.
Linked to the great needs of humanity, always have appeared important technologies. The need for human communication emerged the telephone, television, radio, internet.With health needs, advances in surgery, general medicine, clinical analysis emerged. With the economic needs have emerged new industrial technologies, technologies of extraction processes. And could continue indefinitely, because there is no field in which technology is not present: in the economic, industrial, social, political, scientific, legislative, educational etc. as it allows an improvement of the end result or a simplification of the intermediate processes. Very associated with this is the concept of BAT (Best Avaliable Technology). This term is based on many of the modern concepts of ecology and sustainability, through the continuous improvement of the technologies used in the industry to avoid contamination.
The previous term has changed in recent years the old concept of technology as a incrementadora for the final performance. Before new techniques directly sought the greatest benefit possible, above all to be developed in 99% of cases and for companies seeking economic performance. The big problems after the industrial revolution, including not only the social but the environmental, are a clear example of wrong of such an approach. Today intends not only to increase production, but that new technologies take care of other aspects, such as the social, the welfare of the workers or the environmental benefit.
