Technology is defined as the practical application of science to commerce or industry. It is the technical means people use to improve their surroundings. It is also a knowledge of using tools and machines to do tasks efficiently. We use technology to control the world in which we live. Technology is people using knowledge, tools, and systems to make their lives easier and better.
People use technology to improve their ability to do work. Through technology, people communicate better. The huge number of technological innovations in telecommunications exemplifies this. Every month there will be a new handphone out in the market. The Internet is also getting more sophisticated, which allows one person to communicate to another person at the other end of the world. Technology allows people to make more and better products. It is through biotechnology that we get better and more insect-resistant food. Our buildings are better through the use of technology.
Often the terms, technology and science, are confused. Technology is said to be "applied science". This is not true. Science deals with the natural world. Technology is the study of the natural laws that govern the universe.
Science tells us that objects will fall to the earth (law of gravity). Science tells us that steel exposed to oxygen will rust (chemistry). Science tells us that cross-pollinating plants will produce predictable results (biology). On the other hand, technology deals with the human-made world. It is the study of ways people develop and use technical means - tools and machines. It tells us how to control the natural and human-made world.
This is not to say science and technology are unrelated. Science deals with "understanding" while technology deals with "doing". Science helps us know how to do something efficiently.
Technology is rapidly changing our world. It is bringing us services beyond our grandparents' wildest dreams. It seems that with each year the pace of change quickens. Each new process or invention makes still other advances possible. For example, the advancement of the movie industry (from silent movies to talking movies) allows for computer technology to be incorporated into movie-making.
