We live in a world that is mechanized and high on technology, we keep telling each other. But we scarcely bother about getting to the bottom of the concept of technology and defining it. That is something we left behind us way back in school. So now, it’s not a bad idea getting to the very definition of technology, and understanding it in terms of things familiar to us.
