Application of scientific knowledge A steam turbine with the case opened. Such turbines produce most of the electrical energy used today. Electricity usage and living requirements are extremely associated. Electrification is thought to be the most crucial engineering achievement of the 20th century.  Technology (" science of craft", from Greek, techne, "art, ability, cunning of hand"; and -,) is the sum of techniques, abilities, approaches, and processes used in the production of products or services or in the accomplishment of goals, such as clinical examination.
Systems (e. g. devices) using technology by taking an input, changing it according to the system's usage, and after that producing an outcome are referred to as technology systems or technological systems. The easiest type of innovation is the advancement and usage of standard tools. The ancient discovery of how to manage fire and the later Neolithic Revolution increased the available sources of food, and the development of the wheel helped humans to travel in and control their environment.
Innovation has many impacts. It has actually helped establish advanced economies (including today's international economy) and has permitted the increase of a leisure class. Numerous technological processes produce undesirable spin-offs referred to as pollution and deplete natural resources to the detriment of Earth's environment. Developments have always affected the values of a society and raised brand-new concerns in the ethics of technology.
Philosophical debates have actually emerged over using technology, with arguments over whether innovation enhances the human condition or aggravates it. Neo-Luddism, anarcho-primitivism, and similar reactionary movements criticize the pervasiveness of technology, arguing that it harms the environment and pushes away individuals; advocates of ideologies such as transhumanism and techno-progressivism view continued technological development as useful to society and the human condition.
Before the 20th century, the term was uncommon in English, and it was utilized either to describe the description or study of the beneficial arts or to mention technical education, as in the Massachusetts Institute of Innovation (chartered in 1861). The term "technology" rose to prominence in the 20th century in connection with the 2nd Industrial Transformation.
