The word technology comes from two Greek words, transliterated techne and logos. Techne means art, skill, craft, or the way, manner, or means by which a thing is gained. Logos means word, the utterance by which inward thought is expressed, a saying, or an expression. So, literally, technology means words or discourse about the way things are gained.
Lately, technology has come to mean something different. In one respect, the term has come to mean something narrower -- the above definition would admit art or politics as means of gain, yet though those activities are permeated by technology now, most of us would not consider them to be examples or subsets of technology. In another respect, this definition is too narrow, for when most of us speak of technology today, we mean more than just discourse about means of gain.
The term technology refers to purposefully applying Scientific knowledge for practical uses.
Mostly it refers to a collection of techniques or processes applied in  production of goods and also in the achievement of objectives, such as scientific discoveries or inventions.
