This article is about the use and knowledge of techniques and processes for producing goods and services
("science of craft", from Greek τέχνη, techne, "art, skill, cunning of hand"; and -λογία, -logia) is the collection of techniques, skills, methods and processes used in the production of goods or services or in the accomplishment of objectives, such as scientific investigation. Technology can be the knowledge
of techniques, processes, etc. or it can be embedded in machines,
computers, devices and factories, which can be operated by individuals
without detailed knowledge of the workings of such things.
The human species' use of technology began with the conversion of natural resources into simple tools. The prehistoric discovery of how to control fire and the later Neolithic Revolution increased the available sources of food and the invention of the wheel helped humans to travel in and control their environment. Developments in historic times, including the printing press, the telephone, and the Internet, have lessened physical barriers to communication and allowed humans to interact freely on a global scale. The steady progress of military technology has brought weapons of ever-increasing destructive power, from clubs to nuclear weapons.
Technology has many effects. It has helped develop more advanced economies (including today's global economy) and has allowed the rise of a leisure class. Many technological processes produce unwanted by-products, known as pollution, and deplete natural resources, to the detriment of Earth's environment. Various implementations of technology influence the values of a society and new technology often raises new ethical questions. Examples include the rise of the notion of efficiency in terms of human productivity, a term originally applied only to machines, and the challenge of traditional norms.
Philosophical debates have arisen over the use of technology, with disagreements over whether technology improves the human condition or worsens it. Neo-Luddism, anarcho-primitivism,
and similar reactionary movements criticise the pervasiveness of
technology in the modern world, opining that it harms the environment
and alienates people; proponents of ideologies such as transhumanism and techno-progressivism view continued technological progress as beneficial to society and the human condition
Technology is the collection of tools, including machinery, modifications, arrangements and procedures used by humans
History
The history of technology is the history of the invention of tools and techniques and is similar to other sides of the history of humanity. Technology can refer to methods ranging from as simple as language and stone tools to the complex genetic engineering and information technology that has emerged since the 1980s.
New knowledge has enabled people to create new things, and conversely, many scientific endeavors are made possible by technologies which assist humans in travelling to places they could not previously reach, and by scientific instruments by which we study nature in more detail than our natural senses allow.
Since much of technology is applied science, technical history is connected to the history of science. Since technology uses resources, technical history is tightly connected to economic history. From those resources, technology produces other resources, including technological artifacts used in everyday life.
Technological change affects, and is affected by, a society's cultural traditions. It is a force for economic growth and a means to develop and project economic, political and military power.

Science, engineering and technology
The distinction between science, engineering and technology is not always clear. Science is the reasoned investigation or study of natural phenomena, aimed at discovering enduring principles among elements of the phenomenal world by employing formal techniques such as the scientific method. Technologies are not usually exclusively products of science, because they have to satisfy requirements such as utility, usability and safety.
Engineering is the goal-oriented
process of designing and making tools and systems to exploit natural
phenomena for practical human means, often (but not always) using
results and techniques from science. The development of technology may
draw upon many fields of knowledge, including scientific, engineering, mathematical, linguistic, and historical knowledge, to achieve some practical result
Technology is often a consequence of science and engineering — although
technology as a human activity precedes the two fields. For example,
science might study the flow of electrons in electrical conductors,
by using already-existing tools and knowledge. This new-found knowledge
may then be used by engineers to create new tools and machines, such as
semiconductors, computers,
and other forms of advanced technology. In this sense, scientists and
engineers may both be considered technologists; the three fields are
often considered as one for the purposes of research and reference
The exact relations between science and technology in particular have
been debated by scientists, historians, and policymakers in the late
20th century, in part because the debate can inform the funding of basic
and applied science. In the immediate wake of World War II,
for example, in the United States it was widely considered that
technology was simply "applied science" and that to fund basic science
was to reap technological results in due time. An articulation of this
philosophy could be found explicitly in Vannevar Bush's treatise on postwar science policy, Science—The Endless Frontier:
"New products, new industries, and more jobs require continuous
additions to knowledge of the laws of nature ... This essential new
knowledge can be obtained only through basic scientific research." In
the late-1960s, however, this view came under direct attack, leading
towards initiatives to fund science for specific tasks (initiatives
resisted by the scientific community). The issue remains
contentious—though most analysts resist the model that technology simply
is a result of scientific research
