Knowledge of methods of achieving goals A steam turbine with the case opened. Such turbines produce the majority of the electrical energy used today. Electrical energy usage and living standards are highly associated. Electrification is thought to be the most essential engineering accomplishment of the 20th century.  Technology (" science of craft", from Greek, techne, "art, ability, cunning of hand"; and -,) is the amount of strategies, abilities, approaches, and processes utilized in the production of products or services or in the achievement of goals, such as clinical examination.
Systems (e. g. machines) using technology by taking an input, changing it according to the system's use, and then producing an result are described as innovation systems or technological systems. The simplest form of technology is the development and use of standard tools. The ancient discovery of how to control fire and the later Neolithic Revolution increased the available sources of food, and the innovation of the wheel assisted humans to travel in and control their environment.
Innovation has many effects. It has actually assisted establish more innovative economies (consisting of today's worldwide economy) and has actually enabled the rise of a leisure class. Many technological procedures produce unwanted by-products referred to as pollution and diminish natural deposits to the hinderance of Earth's environment. Developments have actually always affected the worths of a society and raised brand-new questions in the ethics of innovation.
Philosophical debates have actually occurred over using technology, with disagreements over whether innovation improves the human condition or aggravates it. Neo-Luddism, anarcho-primitivism, and comparable reactionary movements slam the pervasiveness of innovation, arguing that it harms the environment and alienates people; advocates of ideologies such as transhumanism and techno-progressivism view continued technological development as advantageous to society and the human condition.
Prior to the 20th century, the term was unusual in English, and it was used either to refer to the description or study of the beneficial arts or to allude to technical education, as in the Massachusetts Institute of Innovation (chartered in 1861). The term "technology" increased to prominence in the 20th century in connection with the Second Industrial Revolution.
