Technology is a term, which refers whatever can be said at any particular historical period, concerning the state of the art in the whole general field of practical know-how and tool use. It therefore includes all that can be said about arts, crafts, professions, applied sciences, and skills. By extension it can also refer to any systems or methods of organization which enable such technologies, any field of study which concerns them, or any products which result. The etymology of the word technology still reflects the modern meaning, coming from the Greek technología — téchnē, an 'art', 'skill' or 'craft' and -logía, the study of something, or the branch of knowledge of a discipline. The term can either be applied generally or to specific areas: examples include "Bio-technology", "medical technology", or "state-of-the-art technology", now it is also in "educational technology".
