Technology

Technology is the study and knowledge of the practical applications of scientific discoveries; e.g. for the production of goods and services that improve the human condition and environment. The processes by which human beings fashion tools and machines to increase their control and understanding of the material environment. Technology is closely related to science and engineering. It includes the development of new materials, machinery, and processes that improve production and solve technical problems. Agriculture, Engineering, Radio, Space, Television, Transport

The use of tools, machines, materials, techniques, and sources of power to make work easier and more productive. Industrial technology began 200 years ago with the introduction of power-driven machines, the growth of factories, and the mass production of goods.

Whereas science is concerned with understanding how and why things happen, technology deals with making things happen; it can be subdivided into many specializations, such as medical, military, and nuclear. Technology has helped people to gain control over nature, and so build a civilized world. Undesirable side-effects include increased pollution and loss of jobs as a result of automation.

Agriculture Agriculture is the science and practice of cultivating of land, producing crops, and raising animals. It also refers to many associated processes or enterprises, such as food processing.
