Science and Technology may sound similar in various aspect and they are often interchanged, but if observed carefully then both have a large difference.
We could differentiate them easily by their definition. Science is a systematic knowledge base, where the steps in procedure involved could reliably predict the type of outcome. Science is mainly used by the domain of science like chemistry, physics, biology and psychology, whereas Technology is somewhat more of practical use or applied science.
Here Tools and knowledge are used together for the study of a particular scientific field. For example, in science can teach you about the electric field, electricity working process but with Technology and knowledge about it, you can develop a motor, which is simply based on the Science rules and can give you a practical desired output. Overall we can say that Science is all about theories and Technology is all about the practical use of it in daily life.
It has been said that science is for the pursuit of knowledge and Technology is to create system according to the people’s need. Science consists of controlled experiments, analysis, generalizations, creation, logical skills, inventions and theories, whereas technology consists of skills like designing, construction, quality checking, problem-solving and testing purpose.
Another main difference is that Science is always useful but Technology can be both useful and harmful. For example, Science gives you theory about the Atom Bomb, which is useful to know that such logic also exists but Technology gives you the practical invention of it and thus it becomes a deadly weapon for humanity.
Science is used to make a prediction in every field whereas Technology mainly focuses on making life easier for the human being. Technology mainly focus to create products, which are implementing some scientific principle, like smart-phones, Telecommunications, calculator, etc.
