Technology
1. Technology is the usage and knowledge of tools, techniques, and crafts, or is systems or methods of organization, or is a material product of these things. The word technology comes from the Greek technología meaning craft and the study of something, or the branch of knowledge of a discipline. The term can either be applied generally or to specific areas. 
2. Technologies significantly affect human as well as other animal species ability to control and adapt to their natural environments. The human species use of technology began with the conversion of natural resources into simple tools. The prehistorical discovery of the ability to control fire increased the available sources of food and the invention of the wheel helped humans in travelling in and controlling their environment. 3. Recent technological developments, 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. However, not all technology has been used for peaceful purposes; the development of weapons of ever-increasing destructive power has progressed throughout history, from clubs to nuclear weapons.
