What is technology?




• Technology is the use of scientific knowledge for practical purposes or
applications, whether in industry or in our everyday lives.

• So, basically, whenever we use our scientific knowledge to achieve
some specific purpose, we're using technology.



• Well, there is slightly more to it than that.



• Technology usually involves a specific piece of equipment, but
that equipment can be incredibly simple or dazzlingly complex.
• It can be anything from the discovery of the wheel, all the way up

to computers and MP4 players.
