According to wikipedia
Technology is the usage and knowledge of tools, techniques, and crafts, or is systems or methods of organization, or is a material product (such as clothing) of these things. The word technology comes from the Greek technología (??????????) — téchn? (?????), ‘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 “construction technology”, “medical technology”, or “state-of-the-art technology”.
