Knowledge of ways of accomplishing goals A steam turbine with the case opened. Such turbines produce the majority of the electrical energy used today. Electrical power intake and living requirements are highly associated. Electrification is believed to be the most crucial engineering achievement of the 20th century.  Technology (" science of craft", from Greek, techne, "art, ability, shrewd of hand"; and -,) is the amount of methods, abilities, techniques, and processes used in the production of products or services or in the achievement of goals, such as clinical investigation.
Systems (e. g. devices) using technology by taking an input, altering it according to the system's use, and after that producing an outcome are described as innovation systems or technological systems. The most basic type of technology is the advancement and use of basic tools. The prehistoric discovery of how to manage fire and the later Neolithic Transformation increased the readily available sources of food, and the innovation of the wheel assisted human beings to travel in and manage their environment.
Technology has lots of results. It has actually assisted establish more sophisticated economies (including today's international economy) and has enabled the increase of a leisure class. Numerous technological processes produce undesirable by-products known as pollution and deplete natural resources to the hinderance of Earth's environment. Innovations have actually constantly influenced the worths of a society and raised new questions in the principles of technology.
Philosophical disputes have actually occurred over using technology, with disputes over whether innovation enhances the human condition or worsens it. Neo-Luddism, anarcho-primitivism, and comparable reactionary motions slam the pervasiveness of innovation, arguing that it hurts the environment and alienates people; advocates of ideologies such as transhumanism and techno-progressivism view continued technological progress as beneficial to society and the human condition.
Before the 20th century, the term was unusual in English, and it was utilized either to describe the description or research study of the useful arts or to point to technical education, as in the Massachusetts Institute of Innovation (chartered in 1861). The term "innovation" increased to prominence in the 20th century in connection with the 2nd Industrial Revolution.
