Technology is the making, usage, and knowledge of tools, machines, techniques, crafts, systems or methods of organization in order to solve a problem or perform a specific function. It can also refer to the collection of such tools, machinery, and procedures. The word technology term can either be applied generally or to specific areas: examples include construction technology, medical technology, and information technology.

Technology can be most broadly defined as the entities, both material and immaterial, created by the application of mental and physical effort in order to achieve some value. In this usage, technology refers to tools and machines that may accelerator. Tools and machines need not be material; virtual technology, such as computer software and business methods, fall under this definition of technology

Technology is often a consequence of science and engineeringo 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 machinesdered technologists; the three fields are often considered as one for the purposes of research and reference
