ABSTRACT
The word technology comes from the Greek τεχνoλoγία(technología), from τέχνη(téchne), meaning ‘art, skill, craft’, and - λoγία(-logía), meaning ‘study of’. As a discipline it is an applied science concerned with the knowledge and skill needed to invent and develop tools, machines and techniques in order to solve practical problems. ‘Technologies’ refers to the tools themselves that enable human beings to shape and change the physical world. Seen in this way, it is possible to think of the alphabet, paper, the ballpoint pen, the printing press, computers and the internet as technologies that have changed the way we are able to communicate.
